The Quantum Chernoff Bound
K. M. R. Audenaert, J. Calsamiglia, Ll. Masanes +4
We consider the problem of discriminating two different quantum states in the setting of asymptotically many copies, and determine the optimal strategy that minimizes the total pro…
Creating and probing macroscoping entanglement with light
M. Paternostro, D. Vitali, S. Gigan +4
We describe a scheme showing signatures of macroscopic optomechanical entanglement generated by radiation pressure in a cavity system with a massive movable mirror. The system we c…
N-representability is QMA-complete
Y. -K. Liu, M. Christandl, F. Verstraete
We study the computational complexity of the N-representability problem in quantum chemistry. We show that this problem is QMA-complete, which is the quantum generalization of NP-c…
Optomechanical entanglement between a movable mirror and a cavity field
D. Vitali, S. Gigan, A. Ferreira +6
We show how stationary entanglement between an optical cavity field mode and a macroscopic vibrating mirror can be generated by means of radiation pressure. We also show how the ge…
Properties of nonfreeness: an entropy measure of electron correlation
Alex D. Gottlieb, Norbert J. Mauser
"Nonfreeness" is the (negative of the) difference between the von Neumann entropies of a given many-fermion state and the free state that has the same 1-particle statistics. It als…
Free-Space distribution of entanglement and single photons over 144 km
R. Ursin, F. Tiefenbacher, T. Schmitt-Manderbach +15
Quantum Entanglement is the essence of quantum physics and inspires fundamental questions about the principles of nature. Moreover it is also the basis for emerging technologies of…
