Experimental demonstration of quantum leader election in linear optics
Yuta Okubo, Xiang-Bin Wang, Yun-Kun Jiang +2
Linear optics is a promising candidate to enable the construction of quantum computers. A number of quantum protocols gates based on linear optics have been demonstrated. However,…
Security analysis of decoy state quantum key distribution incorporating finite statistics
Jun Hasegawa, Masahito Hayashi, Tohya Hiroshima +1
Decoy state method quantum key distribution (QKD) is one of the promising practical solutions to BB84 QKD with coherent light pulses. In the real world, however, statistical fluctu…
Experimental Decoy State Quantum Key Distribution with Unconditional Security Incorporating Finite Statistics
Jun Hasegawa, Masahito Hayashi, Tohya Hiroshima +2
We propose the improved decoy state quantum key distribution incorporating finite statistics due to the finite code length and report on its demonstration. In our experiment, four…
Influence of pure-dephasing by phonons on exciton-photon interfaces: Quantum microscopic theory
Kunihiro Kojima, Akihisa Tomita
We have developed a full quantum microscopic theory to analyze the time evolution of transversal and longitudinal components of an exciton-single photon system coupled to bulk acou…
Quantum non-demolition measurement of photon-arrival using an atom-cavity system
Kunihiro Kojima, Akihisa Tomita
A simple and efficient quantum non-demolition measurement (QND) scheme is proposed in which the arrival of a signal photon is detected without affecting the qubit state. The propos…
