Abstract

Using entangled photons and a low-loss optical delay, we implement a novel quantum cryptography protocol in which every photon contributes to the key, yielding enhanced efficiency, and an advantage for six- versus four-basis state protocols.

Relativistic Quantum Cryptography with Optical Storage

Using a low-loss optical storage loop and polarization entangled photons, we demonstrate a quantum cryptography protocol in which the sifting step is eliminated and every photon may contribute to the final key.

Advanced Quantum Communication Protocols

Paul G. Kwiat

We have realized the first demonstration of "relativistic" quantum cryptography, using both faint laser pulses and entangled photons. By incorporating an optical delay cavity, Bob is able to measure every photon from Alice in the correct basis, leading to enhanced key rates, as well as some security advantages. We have also implemented our proposal for a high-speed quantum random number generator, in which the arrival time of a detected photon is used to generate -8 random bits per photon. Our system produced cryptographically secure bits at over 4 Mbits/s, with a clear path toward even higher rates. In addition, we solved a number of technical problems to produce 99%-fidelity polarization-entangled pairs from a diode-laser pumped source. Extending our previous implementation of remote state preparation, we have incorporated hyperentanglement to successfully remotely prepare entangled states. Finally, we studied the use of hyperentangled photons as a resource for improved quantum dense coding. Although our experimental verification is still in progress, we identified the theoretically optimal configuration, and compared hyperentangled and multi-pair encoding.

Experimental six-state quantum cryptography

Using polarization-entangled photons, we have implemented the “six-state” quantum cryptography protocol, whereby each photon is measured in one of three bases. The resulting eavesdropper-induced error rate, experimentally investigated for several attacks, is enhanced to 33%.

Entangled-photon six-state quantum cryptography

Daphna G. Enzer, Phillip G. Hadley, Richard Hughes +2 more

We have implemented the 'six-state' quantum cryptography protocol using polarization-entangled photon pairs, in which the polarization of each photon of a pair is measured in one of three randomly chosen bases. For a given amount of eavesdropping, this protocol results in a larger error rate than in four- or two-state protocols, but reduces the number of key-producing events. We have experimentally investigated several incoherent eavesdropping strategies, and verified the predicted enhancement in error rate. However, we demonstrate that for low error rates, the efficiency for secret key generation is higher when using the four-state protocol.

What fundamentally new properties are introduced by special relativity to quantum cryptography in open space?

S. N. Molotkov, D. I. Pomozov

A fundamentally new relativistic quantum cryptography protocol has been proposed for key distribution through open space. The protocol guarantees the security of keys at any damping and for a nonstrictly single-photon source of quantum states.
