....principles. The proof of the safety of these methods is based on quantum mechanics; it therefore has a more solid theoretical foundation. Because the quantum devices involved are relatively simple, several models based on the transfer of quantum coded information have already been realized (see [2][4] 8] 1.3 Quantum communication The quantum communication model is based on the communication model of Yao which was presented in his paper [17] This model (the classical one) deals with the issue of communication by considering a situation in which two players A; B wish to evaluate a ....

....computation which are derived from communication hold true for quantum models of computation. Another motivation is an interest in communication for itself. As technology gets more and more sophisticated we have to start looking at quantum devices as a means for transferring information (see [2][4] 8] In this thesis a complete and formal definition of the quantum communication model 8 is given. Afterwards we show how to simulate probabilistic protocols by using quantum communication. This includes: ffl Showing how to amplify the probability of success ffl Showing how to simulate a ....

....new prospects to use quantum mechanical phenomena for processing information. The operation of elementary quantum logic gates using ion traps, cavity QED, and NMR technology has been demonstrated. A primitive Quantum Computer(pu [1 4] and secure quantum cryptographic systems have been build [5 7]. Recent theoretical work has shown that a QC has the potential of solving certain computationally hard problems such as factoring integers and searching databases much faster than a conventional computer [8 13] The fact that a QC might be more powerful than an ordinary computer is based on ....

....Even entangled pairs of atoms were created[114] However quantum computation is advantageous only when macroscopically many particles are entangled[118, 6] a task which seems impossible as of now. Promising experimental developments come from the closely related subject of quantum cryptography[50, 34, 46]. Quantum communication was successfully tested[116, 147] Bouwmeester et al. have recently reported on experimental realization of quantum teleportation[43] Suggestions for implementations of quantum computation [63, 74, 104, 142, 85, 117, 37, 145, 117, 160, 163, 182] include quantum dots, ....

....although such a possibility exists in principle, there should be very little concern that the protocol be broken this way in practice. 4.8. 3 Conclusion The reader interested in the practical implementation of the quantum transfer should consult Bennett and Brassard s article on the topic [BB89]. As this thesis is being completed, experiments leading to physical implementation of the transfer are being run by Bennett and Brassard. Their results are extremely promising. At this time, their device can do a quantum transfer over a distance of 30 centimeters with a crossover frequency of ....

....out. Much later, it was in SIGACT News that Wiesner s paper finally appeared [74] in the wake of the first author s early collaboration with Charles H. Bennett [7] It was also in SIGACT News that the original experimental demonstration for quantum key distribution was announced for the first time [6] and that a thorough bibliography was published [19] Finally, it was in SIGACT News that Doug Wiedemann chose to publish his discovery when he reinvented quantum key distribution in 1987, unaware of all previous work but Wiesner s [73, 5] Most of the first decade of the history of quantum ....

....whose work we may have omitted. Note that we do not necessarily agree with the claims in every paper mentioned here: this column should not be construed as a seal of approval 2 Implementation of Quantum Key Distribution When the first quantum cryptographic prototype was reported in SIGACT News [6] in 1989, it was no more than a proof of feasibility with no claim to practicality since it allowed for the perfectly secure transmission of cryptographic material over a distance of 32 centimetres (See also [3] for a more complete coverage. Since then, significantly more sophisticated ....

This work was performed while this author was visiting IBM Research. yy Physics Department, University of California at Los Angeles, Los Angeles, CA 90024, USA. 1 Introduction and History Quantum cryptography has entered the experimental era [5]. The first convincingly successful quantum exchange took place in October 1989. After a short historical review of quantum cryptography, we report on the new apparatus and the latest results obtained with it. Quantum cryptography was born in the late sixties when Stephen Wiesner wrote Conjugate ....
