On the Security of the Ping-Pong Protocol
Kim Bostroem, Timo Felbinger
We briefly review the security of the ping-pong protocol in light of several attack scenarios suggested by various authors since the proposal of the protocol. We refute one recent…
Comment on "Secure direct communication with a quantum one-time pad"
H. Hoffmann, K. Bostroem, T. Felbinger
In the paper [Phys. Rev. A \textbf{69}, 052319 (2004)], a quantum direct communication protocol is proposed which is claimed to be unconditionally secure even for the case of a noi…
Deterministic Secure Direct Communication Using Entanglement
Kim Bostroem, Timo Felbinger
A novel secure communication protocol is presented, based on an entangled pair of qubits and allowing asymptotically secure key distribution and quasi-secure direct communication.…
Secure direct communication using entanglement
Kim Bostroem
A novel communication protocol based on an entangled pair of qubits is presented, allowing secure direct communication from one party to another without the need for a shared secre…
Lossless quantum data compression and variable-length coding
Kim Bostroem, Timo Felbinger
In order to compress quantum messages without loss of information it is necessary to allow the length of the encoded messages to vary. We develop a general framework for variable-l…
Time correlations of a laser-induced Bose-Einstein condensate
T. Felbinger, L. Santos, M. Wilkens +1
We analyze the multi-time correlations of a laser-induced Bose-Einstein condensate. We use quantum stochastic methods to obtain under certain circumstances a Fokker-Planck equation…
