Journal ArticleDOI
Quantum Communication Through an Unmodulated Spin Chain
TL;DR: It is found that in a reasonable time, a qubit can be directly transmitted with better than classical fidelity across the full length of chains of up to 80 spins, and the channel allows distillable entanglement to be shared over arbitrary distances.
Journal ArticleDOI
Natural thermal and magnetic entanglement in the 1D Heisenberg model.
TL;DR: It is found that the entanglement in an antiferromagnetic chain can be increased by increasing the temperature or the external field, and increasing the field can also createEntanglement between otherwise disentangled spins.
Journal ArticleDOI
Multiparticle generalization of entanglement swapping
TL;DR: This work describes how this scheme allows to establish multiparticle entanglement between particles belonging to distant users in a communication network through a prior distribution of singlets followed by only local measurements.
Journal ArticleDOI

TL;DR: It is shown that despite the weakness of gravity, the phase evolution induced by the gravitational interaction of two micron size test masses in adjacent matter-wave interferometers can detectably entangle them even when they are placed far apart enough to keep Casimir-Polder forces at bay.
Journal ArticleDOI
Photon-blockade-induced Mott transitions and XY spin models in coupled cavity arrays
TL;DR: In this article, a Mottinsulator phase of atom-photon excitations (polaritons) can arise in an array of individually addressable coupled electromagnetic cavities when each of these cavities is coupled resonantly to a single two-level system (atom, quantum dot, or Cooper pair).
