Quantum information can be negative
Michal Horodecki, Jonathan Oppenheim, Andreas Winter
Given an unknown quantum state distributed over two systems, we determine how much quantum communication is needed to transfer the full state to one system. This communication meas…
The Universal Composable Security of Quantum Key Distribution
M. Ben-Or, Michal Horodecki, D. W. Leung +2
The existing unconditional security definitions of quantum key distribution (QKD) do not apply to joint attacks over QKD and the subsequent use of the resulting key. In this paper,…
Not So SuperDense Coding - Deterministic Dense Coding with Partially Entangled States
Shay Mozes, Benni Reznik, Jonathan Oppenheim
The utilization of a -level partially entangled state, shared by two parties wishing to communicate classical information without errors over a noiseless quantum channel, is dis…
Compressing compound states
Michal Horodecki, Pawel Horodecki, Jonathan Oppenheim
Quantum compression can be thought of not only as compression of a signal, but also as a form of cooling. In this view, one is interested not in the signal, but in obtaining purity…
Minimum Inaccuracy for Traversal-Time
J. Oppenheim, B. Reznik, W. G. Unruh
Using various model clocks it has been shown that the time-of-arrival cannot be measured more accurately than 1/E where E is the kinetic energy of a free particle. However, this re…
