Repeatable classical one-time-pad crypto-system with quantum mechanics
Fu-Guo Deng, Gui Lu Long
Classical one-time-pad key can only be used once. We show in this Letter that with quantum mechanical information media classical one-time-pad key can be repeatedly used. We propos…
Hyper-parallel Toffoli gate on three-photon system with two degrees of freedom assisted by single-sided optical microcavities
Hai-Rui Wei, Fu-Guo Deng, Gui Lu Long
Encoding qubits in multiple degrees of freedom (DOFs) of a quantum system allows less-decoherence quantum information processing with much less quantum resources. We present a comp…
Complete hyperentangled-Bell-state analysis for quantum communication
Yu-Bo Sheng, Fu-Guo Deng, Gui Lu Long
It is impossible to unambiguously distinguish the four Bell states in polarization, resorting to linear optical elements only. Recently, the hyperentangled Bell state, the simultan…
Reusable Vernam Cipher with Quantum Media
Kai Wen, Fu-Guo Deng, Gui Lu Long
A revised version will be uploaded later. In this Letter, it is shown that the one-time-pad key in the Vernam cipher can be repeatedly used with unconditional security using quantu…
Circular quantum secret sharing
Fu-Guo Deng, Hong-Yu Zhou andGui Lu Long
A circular quantum secret sharing protocol is proposed, which is useful and efficient when one of the parties of secret sharing is remote to the others who are in adjacent, especia…
Grover Algorithm with zero theoretical failure rate
G. L. Long
In standard Grover's algorithm for quantum searching, the probability of finding the marked item is not exactly 1. In this Letter we present a modified version of Grover's algorith…
