Deterministic Secure Direct Communication Using Mixed State
نویسنده
چکیده
We show an improved ping − pong protocol which is based on the protocol showed by Kim Bostrom and Timo Felbinger [Phys. Rev. Lett. 89, 187902 (2002)]. We show that our protocol is asymptotically secure key distribution and quasisecure direct communication using a mixed state. This protocol can be carried out with great efficiency and speed with today’s technology, e.g. single photon source and linear optical elements technology.

A novel secure communication protocol
Quantum key distribution (QKD) is a protocol which is provably secure. Eve cannot gain any information from the qubits transmitted from Alice to Bob without disturbing their state. First , the no-cloning theorem forbids Eve to perfectly clone Alice’s qubit. Second, in any attempt to distinguish between two non-orthogonal quantum states, information gain is only possible at the expense of introd...
متن کاملDeterministic secure communication protocol
Quantum key distribution (QKD) is a protocol which is provably secure, by which private key bit can be created between two parties over a public channel. The key bits can then be used to implement a classical private key cryptosystem, to enable the parties to communicate securely. The basic idea behind QKD is that Eve cannot gain any information from the qubits transmitted from Alice to Bob wit...

Quantum key distribution (QKD) is a protocol which is provably secure, by which private bit can be created between two parties over a public channel. Based on the postulate of quantum measurement [1] and no-cloning theorem [2], different QKD protocol are presented [3]. However, these type of cryptographic schemes are usually nondeterministic. A Beige et al. have presented a quantum communicatio...
متن کاملSecure Bidirectional Quantum Communication Protocol without Quantum Channel
In this letter we propose a theoretical deterministic secure direct bidirectional quantum communication protocol by using swapping quantum entanglement and local unitary operations, in which the quantum channel for photon transmission can be discarded, hence any attack with or without eavesdropping or even the destructive attack without scruple is impossible. Much attention [1-6] has been focus...

We present a deterministic secure direct communication scheme via entanglement swapping, where a set of ordered maximally entangled three-particle states (GHZ states), initially shared by three spatially separated parties, Alice, Bob and Charlie, functions as a quantum information channel. After ensuring the safety of the quantum channel, Alice and Bob apply a series local operations on their r...
