Single-copy entanglement in a gapped quantum spin chain.
The single-copy entanglement of a given many-body quantum system is defined [J. Eisert and M. Cramer, Phys. Rev. A 72, 042112 (2005)10.1103/PhysRevA.72.042112] as the maximal entanglement deterministically distillable from a bipartition of a single specimen of that system. For critical (gapless) spin chains, it was recently shown that this is exactly half the von Neumann entropy [R. Orús, J. I....
متن کاملEntanglement of Pure States for a Single Copy
An optimal local conversion strategy between any two pure states of a bipartite system is presented. It is optimal in that the probability of success is the largest achievable if the parties which share the system, and which can communicate classically, are only allowed to act locally on it. The study of optimal local conversions sheds some light on the entanglement of a single copy of a pure s...
متن کاملMultiple-copy entanglement transformation and entanglement catalysis
We prove that any multiple-copy entanglement transformation fS. Bandyopadhyay, V. Roychowdhury, and U. Sen, Phys. Rev. A 65, 052315 s2002dg can be implemented by a suitable entanglement-assisted local transformation fD. Jonathan and M. B. Plenio, Phys. Rev. Lett. 83, 3566 s1999dg. Furthermore, we show that the combination of multiple-copy entanglement transformation and the entanglement-assiste...
متن کاملAtom-atom entanglement by single-photon detection.
A scheme for entangling distant atoms is realized, as proposed in the seminal paper by [C. Cabrillo et al., Phys. Rev. A 59, 1025 (1999)]. The protocol is based on quantum interference and detection of a single photon scattered from two effectively one meter distant laser cooled and trapped atomic ions. The detection of a single photon heralds entanglement of two internal states of the trapped ...
متن کاملPhoton entanglement detection by a single atom
We use a single trapped 40Ca ion as a resonant, polarizationsensitive absorber to detect and characterize the entanglement of tunable narrowband photon pairs from a spontaneous parametric down-conversion source. Single-photon absorption is marked by a quantum jump in the ion and heralded by coincident detection of the partner photon. For three polarization basis settings of the absorption and d...
