Deterministic Secure Direct Communication Using Entanglement
Kim Joris Boström,Timo Felbinger +1 more
TL;DR: A novel secure communication protocol is presented, based on an entangled pair of qubits and allowing asymptotically secure key distribution and quasisecure direct communication, which also makes commercial applications conceivable.
Journal ArticleDOI
Comment on 'Secure direct communication with a quantum one-time pad'
TL;DR: In this paper, a quantum direct communication protocol is proposed which is claimed to be unconditionally secure even for the case of a noisy channel, but this is not the case by giving an undetectable attack scheme.
Journal ArticleDOI
On the security of the ping-pong protocol
Kim Joris Boström,Timo Felbinger +1 more
TL;DR: The security of the ping-pong protocol is reviewed in light of several attack scenarios suggested by various authors since the proposal of the protocol, and one recent attack is refuted.
Journal ArticleDOI
Classical information and distillable entanglement
TL;DR: It is established a quantitative connection between the amount of lost classical information about a quantum state and the concomitant loss of entanglement, which can be used to determine the quantum capacity of a quantum channel which randomizes the order of transmitted signals.
Journal ArticleDOI
Lossless quantum data compression and variable-length coding
Kim Bostroem,Timo Felbinger +1 more
TL;DR: A general framework for variable-length quantum messages is developed in close analogy to the classical case and it is shown that it is possible to reduce the number of qbits passing through a quantum channel even below the von Neumann entropy by adding a classical side channel.
