Updating Quantum Cryptography Report ver. 1
Donna Dodson, Mikio Fujiwara, Philippe Grangier +24
Quantum cryptographic technology (QCT) is expected to be a fundamental technology for realizing long-term information security even against as-yet-unknown future technologies. More…
How much security does Y-00 protocol provide us ?
Tsuyoshi Nishioka, Toshio Hasegawa, Hirokazu Ishizuka +2
New quantum cryptography, often called Y-00 protocol, has much higher performance than the conventional quantum cryptographies. It seems that the conventional quantum cryptographic…
Key Disclosing in Multiphotons with Quantum Cloning
Tsuyoshi Nishioka, Toshio Hasegawa, Hirokazu Ishizuka
Multiphoton state in quantum cryptography decreases its security. Key disclosing with universal quantum cloning machine (UQCM) is considered in explicit manner. Although UQCM canno…
`Circular type' quantum key distribution
Tsuyoshi Nishioka, Hirokazu Ishizuka, Toshio Hasegawa
`Circular type' interferometric system for quantum key distribution is proposed. The system has naturally self-alignment and compensation of birefringence and also has enough effic…
