The relationship between two flavors of oblivious transfer at the quantum level
Guang-Ping He, Z. D. Wang
Though all-or-nothing oblivious transfer and one-out-of-two oblivious transfer are equivalent in classical cryptography, we here show that due to the nature of quantum cryptography…
Upper bounds of a class of imperfect quantum sealing protocols
Guang-Ping He
The model of the quantum protocols sealing a classical bit is studied. It is shown that there exist upper bounds on its security. For any protocol where the bit can be read correct…
Quantum bit string sealing
Guang-Ping He
Though it was proven that secure quantum sealing of a single classical bit is impossible in principle, here we propose an unconditionally secure quantum sealing protocol which seal…
Exchange Coupling and Decoupling in a Nanocomposite Spin System
Y. Z. Shao, W. R. Zhong, T. Lan +1
We studied the exchange coupling and decoupling occurring in a nanocomposite spin system based on a 3D Heisenberg model by means of Monte Carlo numerical computation simulation. Di…
Bound States and Critical Behavior of the Yukawa Potential
Xiang-Qian Luo, Yong-Yao Li, Helmut Kroger
We investigate the bound states of the Yukawa potential , using different algorithms: solving the Schrödinger equation numerically and our Monte Carlo Hamilton…
