| ==Work==
| | |
| Anton Zeilinger is a pioneer in the field of [[quantum information]] and of the foundations of [[quantum mechanics]]. He realized many important quantum information protocols for the first time, including [[quantum teleportation]] of an independent [[qubit]], entanglement swapping (i.e. the teleportation of an entangled state), hyper-dense coding (which was the first entanglement-based protocol ever realized in experiment), entanglement-based [[quantum cryptography]], one-way [[quantum computation]] and blind [[quantum computation]]. His further contributions to the experimental and conceptual foundations of quantum mechanics include multi-particle [[entanglement]] and matter wave [[interference]] all the way from [[neutrons]] via [[atoms]] to [[macromolecules]] such as [[fullerenes]].

| Most widely known is his first realization of [[quantum teleportation]] of an independent qubit.<ref>D. Bouwmeester, J. W. Pan, K. Mattle, M. Eibl, H. Weinfurter & A.

| ===Entanglement swapping – teleportation of entanglement===
| | |
| Entanglement swapping is the teleportation of an entangled state. After its proposal,<ref>M. Zukowski, A. Zeilinger, M. A. Horne & A.K. Ekert, ''Event-Ready-Detectors Bell Experiment via Entanglement Swapping'', Phys. Rev. Lett. '''71''', 4287-90 (1993). [http://prl.aps.org/abstract/PRL/v71/i26/p4287_1 Abstract].</ref> entanglement swapping has first been realized experimentally by Zeilinger’s group in 1998.<ref>J.-W. Pan, D. Bouwmeester, H. Weinfurter & A. Zeilinger, ''Experimental entanglement swapping: Entangling photons that never interacted'', Phys. Rev. Lett. '''80''' (18), 3891-3894 (1998). [http://prl.aps.org/abstract/PRL/v80/i18/p3891_1 Abstract].</ref> It has recently been applied to carry out a delayed-choice entanglement swapping test.<ref>X.-S. Ma, S.Zotter, J. Kofler, R. Ursin, T. Jennewein, Č. Brukner & A. Zeilinger, ''Experimental delayed-choice entanglement swapping'', Nature Physics '''8''', 479–484 (2012). [http://www.nature.com/nphys/journal/v8/n6/full/nphys2294.html Abstract].</ref> Entanglement swapping is the crucial ingredient for quantum repeaters which are expected to connect future quantum computers.

| | |
| ===Entanglement beyond two qubits – GHZ-states and their realizations===
| |
| Anton Zeilinger contributed decisively to the opening up of the field of multi-particle entanglement. In 1997, he was the first with Greenberger and Horne to work on entanglement of more than two qubits.<ref>D. M. Greenberger, M. A. Horne, A. Shimony & A. Zeilinger, ''Bell’s Theorem without Inequalities'', American Journal of Physics '''58''', 1131-1143 (1990). This paper has become a citation classic.</ref> The resulting GHZ theorem (see [[Greenberger-Horne-Zeilinger state]]) is fundamental for quantum physics, as it provides the most succinct contradiction between local realism and the predictions of quantum mechanics. Also, GHZ states opened up the field of multi-particle entanglement.
| |
| | |
| Surprisingly, multi-particle entangled states exhibit qualitatively different properties compared to two-particle entanglement. In the 1990s, it became the main goal of Zeilinger’s research to realize such GHZ states in the laboratory, which required the development of many new methods and tools.
| |
| | |
| Finally, in 1999, he succeeded in providing the first experimental evidence of entanglement beyond two particles<ref>D. Bouwmeester, J.-W. Pan, M. Daniell, H. Weinfurter & A. Zeilinger, ''Observation of three-photon Greenberger-Horne-Zeilinger entanglement'', Phys.Rev. Lett. '''82''' (7), 1345-1349 (1999). [http://www.nature.com/nphys/journal/v8/n6/full/nphys2294.html Abstract].</ref> and also the first test of quantum nonlocality for GHZ states.<ref>J.-W. Pan, D. Bouwmeester, M. Daniell, H. Weinfurter & A. Zeilinger, ''Experimental test of quantum nonlocality in three-photon Greenberger-Horne-Zeilinger entanglement'', Nature '''403''', 515-519 (2000). [http://www.nature.com/nature/journal/v403/n6769/abs/403515a0.html Abstract].</ref> He also was the first to realize that there are different classes of higher-dimensional entangled states and proposed W-states. Today, multi-particle states became an essential workhorse in quantum computation and thus, GHZ-states have even become an individual entry in the [[Physics and Astronomy Classification Scheme|PACS code]].
| |
| | |
| ===Quantum communication, quantum cryptography, quantum computation===
| |
| In 1996, Anton Zeilinger with his group realized hyper-dense coding.<ref>K. Mattle, H. Weinfurter, P.G. Kwiat & A. Zeilinger, ''Dense Coding in Experimental Quantum Communication'', Phys. Rev. Lett. '''76''', 4656-59 (1996). [http://prl.aps.org/abstract/PRL/v76/i25/p4656_1 Abstract].</ref> There, one can encode into one qubit more than one classical bit of information. This was the first realization of a quantum information protocol with an entangled state, where one is able to achieve something impossible with classical physics.
| |
| | |
| In 1998 (published in 2000),<ref>T. Jennewein, C. Simon, G. Weihs, H. Weinfurter & A. Zeilinger, ''Quantum Cryptography with Entangled Photons'', Phys. Rev. Lett. '''84''', 4729–4732 (2000). [http://prl.aps.org/abstract/PRL/v84/i20/p4729_1 Abstract]. This paper was featured in several popular science magazines, both online and in print.</ref> his group was the first to implement [[quantum cryptography]] with [[quantum entanglement|entangled photons]]. Zeilinger’s group is now also developing a quantum cryptography prototype in collaboration with industry.
| |
| | |
| He then also applied quantum entanglement to optical [[quantum information|quantum computation]], where in 2005,<ref>P. Walther, K.J. Resch, T. Rudolph, E. Schenck, H. Weinfurter, V. Vedral, M. Aspelmeyer & A. Zeilinger, ''Experimental one-way quantum computing'', Nature '''434''' (7030), 169-176 (2005). [http://www.nature.com/nature/journal/v434/n7030/abs/nature03347.html Abstract].</ref> he performed the first implementation of one-way quantum computation. This is a protocol based on quantum measurement as proposed by Knill, Laflamme and Milburn.<ref>E. Knill, R. Laflamme & G. J. Milburn, ''A scheme for efficient quantum computation with linear optics'', Nature '''409''', 46-52 (2001). [http://www.nature.com/nature/journal/v409/n6816/abs/409046a0.html Abstract].</ref> Most recently, it has been shown<ref>S. Barz, E. Kashefi, A. Broadbent, J. F. Fitzsimons, A. Zeilinger & P. Walther, ''Demonstration of Blind Quantum Computing'', Science '''20''', 303-308 (2012). [http://www.sciencemag.org/content/335/6066/303.abstract Abstract].</ref> that one-way quantum computation can be used to implement blind quantum computing. This solves a problem in [[Cloud computing]], namely that, whatever algorithm a client employs on a quantum server is completely unknown, i.e. blind, to the operator of the server.
| |
| | |
| The experiments of Zeilinger and his group on the distribution of entanglement over large distances began with both free-space and fiber-based quantum communication and teleportation between laboratories located on the different sides of the river [[Danube]]. This was then extended to larger distances across the city of [[Vienna]] and over 144 km between two [[Canary Islands]], resulting in a successful demonstration that [[quantum communication]] with satellites is feasible. His dream is to put sources of entangled light onto a satellite in orbit.<ref name="autogenerated1"/> A first step was achieved during an experiment at the Italian Matera Laser Ranging Observatory.<ref>P. Villoresi, T. Jennewein, F. Tamburini, M. Aspelmeyer, C. Bonato, R. Ursin, C. Pernechele, V. Luceri, G. Bianco, A. Zeilinger & C. Barbieri,[http://arxiv.org/abs/0803.1871v1 ''Experimental verification of the feasibility of a quantum channel between Space and Earth''], New Journal of Physics '''10''', 033038 (2008).</ref>

| | |
| ===Further novel entangled states===
| |
| With his group, Anton Zeilinger made many contributions to the realization of novel entangled states. The source for polarization-entangled photon pairs developed with Paul Kwiat when he was a PostDoc in Zeilinger's group<ref>P.G. Kwiat, K. Mattle, H. Weinfurter, A. Zeilinger, A.V. Sergienko & Y.H. Shih, ''New High-Intensity Source of Polarization-Entangled Photon Pairs'', Phys. Rev. Lett. '''75''' (24), 4337-41 (1995). [http://prl.aps.org/abstract/PRL/v75/i24/p4337_1 Abstract].</ref> became a workhorse in many laboratories world-wide. The first demonstration of entanglement of orbital angular momentum of photons <ref>A. Mair, A. Vaziri, G. Weihs & A. Zeilinger, ''Entanglement of the orbital angular momentum states of photons'', Nature '''412''' (6844), 313-316 (2001). [http://www.nature.com/nature/journal/v412/n6844/full/412313a0.html Abstract].</ref> opened up a new burgeoning field of research in many laboratories.
| |
| | |
| ===Macroscopic quantum superposition===
| |
| Zeilinger is also interested to extend quantum mechanics into the macroscopic domain. In the early 1990s, he started experiments in the field of atom optics. He developed a number of ways to coherently manipulate atomic beams, many of which, like the coherent energy shift of an atomic [[Matter wave|De Broglie wave]] upon diffraction at a time-modulated light wave, have become cornerstones of today’s ultracold atom experiments. In 1999, Zeilinger abandoned atom optics for experiments with very complex and massive macro-molecules – [[fullerene]]s. The successful demonstration of quantum interference for these <math>C_{60} </math> and <math>C_{70} </math> molecules<ref>M. Arndt, O. Nairz, J. Voss-Andreae, C. Keller, G. van der Zouw & A. Zeilinger, ''Wave-particle duality of C60 molecules'', Nature '''401''', 680-682 (1999). [http://www.nature.com/nature/journal/v401/n6754/abs/401680a0.html Abstract].

Key results include the most precise quantitative study to date of decoherence by thermal radiation and by atomic collisions and the first quantum interference of complex biological macro-molecules. This work is continued by Markus Arndt.
| |
| | |
| In 2005, Zeilinger with his group again started a new field, the quantum physics of mechanical cantilevers. The group was the first – in the year 2006 along with work from Heidmann in Paris and Kippenberg in Garching – to demonstrate experimentally the self-cooling of a micro-mirror by [[radiation pressure]], that is, without feedback.<ref>S. Gigan, H. R. Böhm, M. Paternostro, F. Blaser, G. Langer, J. B. Hertzberg, K. Schwab, D. Bäuerle, M. Aspelmeyer & A. Zeilinger, ''Self-cooling of a micro-mirror by radiation pressure'', Nature '''444''', 67-70 (2006). [http://www.nature.com/nature/journal/v444/n7115/abs/nature05273.html Abstract]. Selected as “Highlight of the recent literature” by [[Science (journal)|Science]] (January 2007).</ref> That phenomenon can be seen as a consequence of the coupling of a high-entropy mechanical system with a low-entropy radiation field. This work is now continued independently by [[Markus Aspelmeyer]].
| |
| | |
| Most recently, using orbital angular momentum states, he was able to demonstrate entanglement of angular momentum up to 300 ħ.<ref>R. Fickler, R. Lapkiewicz, W. N. Plick, M. Krenn, C. Schäff, S. Ramelow & A. Zeilinger, ''Quantum entanglement of high angular momenta'', Science '''338''', 640-643 (2012). [http://www.sciencemag.org/content/338/6107/640.abstract Abstract]. Selected as one of the top 10 breakthroughs of the year 2012 by [[Institute of Physics|IOP’s]] [[Physics World]]. Also featured in [[Deutsche Physikalische Gesellschaft|DPG’s]] [[Physikalische Blätter|Physik Journal]].</ref>

| | |
| ===Further fundamental tests===
| |
| Zeilinger’s program of fundamental tests of quantum mechanics is aimed at implementing experimental realizations of many non-classical features of quantum physics for individual systems. In 1998,<ref>G. Weihs, T. Jennewein, C. Simon, H. Weinfurter & A. Zeilinger, ''Violation of Bell’s inequality under strict Einstein locality conditions'', Phys. Rev. Lett. '''81''' (23), 5039-5043 (1998). [http://prl.aps.org/abstract/PRL/v81/i23/p5039_1 Abstract]. This paper is a classic. It is cited (among others) in the German Wikipedia article on Bell’s inequality and in several popular science books and science books for University students.</ref> he provided the final test of [[Bell states|Bell’s inequality]] closing the communication loophole by using superfast random number generators. More recently, his group also realized the first Bell inequality experiment implementing the freedom-of-choice condition<ref>T. Scheidl, R. Ursin, J. Kofler, S. Ramelow, X. Ma, T. Herbst, L. Ratschbacher, A. Fedrizzi, N. K. Langford, T. Jennewein & A. Zeilinger, ''Violation of local realism with freedom of choice'', PNAS '''107''' (46), 19709 – 19713 (2010). [http://www.pnas.org/content/early/2010/10/29/1002780107 Abstract]</ref> and, most recently<ref>M. Giustina et al., in press.</ref>], they provided for photons the first realization of a Bell test without the fair sampling assumption. All these experiments are not only of fundamental interest, but also important for quantum cryptography. A finally loophole-free entanglement-based implementation of quantum cryptography is generally considered to be absolutely secure against any eavesdropping.
| |
| | |
| Among the further fundamental tests he performed the most notable one is his test of a large class of nonlocal realistic theories proposed by [[Anthony James Leggett|Leggett]].<ref>A. J. Leggett, ''Nonlocal Hidden-Variable Theories and Quantum Mechanics: An Incompatibility Theorem'', Foundations of Physics '''33''' (10), 1469-1493 (2003)(doi:10.1023/A:1026096313729) [http://link.springer.com/article/10.1023%2FA%3A1026096313729 Abstract].</ref> The group of theories excluded by that experiment can be classified as those which allow reasonable subdivision of ensembles into sub-ensembles. It goes significantly beyond [[Bell's theorem]]. While Bell showed that a theory which is both local and realistic is at variance with quantum mechanics, Leggett considered nonlocal realistic theories where the individual photons are assumed to carry polarization. The resulting [[Leggett inequality]] was shown to be violated in the experiments of the Zeilinger group.<ref>S. Gröblacher, T. Paterek, R. Kaltenbaek, C. Brukner, M. Zukowski, M. Aspelmeyer & A. Zeilinger, ''An experimental test of non-local realism'', Nature '''446''', 871-875 (2007). [http://www.nature.com/nature/journal/v446/n7138/abs/nature05677.html Abstract].</ref>
| |
| | |
| In an analogous way, his group showed that even quantum systems where entanglement is not possible exhibit non-classical features which cannot be explained by underlying non-contextual probability distributions.<ref>R. Lapkiewicz, P. Li, C. Schäff, N. K. Langford, S. Ramelow, M. Wiesniak & A. Zeilinger, ''Experimental non-classicality of an indivisible quantum system'', Nature '''474''', 490–493 (2011).[http://www.nature.com/nature/journal/v474/n7352/full/nature10119.html Abstract]</ref> It is expected that these latter experiments will also open up novel ways for quantum information.

| | |
| ===Neutron interferometry===
| |
| Anton Zeilinger’s earliest work is perhaps his least known. His work on neutron interferometry has provided an important foundation for his later research achievements.
| |
| As a member of the group of his thesis supervisor, [[Helmut Rauch]], at the [[Vienna University of Technology|Technical University of Vienna]], Zeilinger participated in a number of neutron interferometry experiments at the [[Institut Laue–Langevin]] (ILL) in Grenoble. His very first such experiment confirmed a fundamental prediction of quantum mechanics, the sign change of a spinor phase upon rotation. This was followed by the first experimental realization of coherent spin superposition of [[matter waves]]. He continued his work in [[neutron interferometry]] at [[MIT]] with [[Clifford Shull|C.G. Shull]] ([[Nobel Laureate]], focusing specifically on dynamical diffraction effects of [[neutrons]] in perfect crystals which are due to multi-wave coherent superposition. After his return to Europe, he built up an interferometer for very cold neutrons which preceded later similar experiments with atoms. The fundamental experiments there included a most precise test of the linearity of quantum mechanics and a beautiful [[double-slit experiment|double-slit diffraction experiment]] with only one neutron at a time in the apparatus. Actually, in that experiment, while one neutron was registered, the next neutron still resided in its [[Uranium]] nucleus waiting for fission to happen.
| |
| | |
| Then, as a professor at the University of Innsbruck, Zeilinger started experiments on entangled photons, as the low [[phase space]] density of neutrons produced by reactors precluded their use in such experiments.
