Quantum Coin Tossing

Won Young Hwang, In Gyu Koh, Yeong Deok Han

We show that a secure quantum protocol for coin tossing exist. The existence of quantum coin tossing support the conjecture of D.Mayers [Phys.Rev.Lett. 78, 3414(1997)] that only as…

The quantum cryptography and the unambiguous measurement of quantum nonorthogonal states

Won Young Hwang, In Gyu Koh, Yeong Deok Han

We discuss the unambiguous measurement of quantum nonorthogonal states in connection with the quantum cryptography. We show that checking a ratio of null one to signal is essential…

Quantum Cryptography without Public Announcement of Bases

Won Young Hwang, In Gyu Koh, Yeong Deok Han

This paper provides a simple variation of the basic ideas of the BB84 quantum cryptographic scheme leading to a method of key expansion. A secure random sequence (the bases sequenc…
