Spatial entanglement in optical parametric oscillators with photonic crystals
entanglement optical parametric oscillators photonic crystals
2010/11/8
The effects of an intracavity photonic crystal in a multimode optical parametric oscillator are studied, with a special focus on quantum fluctuations. The capability to either stimulate or inhibit the...
Deterministic polarization-entanglement purification using spatial entanglement
Deterministic polarization-entanglement purification spatial entanglement
2010/11/8
We present an efficient entanglement purification protocol with hyperentanglement in which additional spatial entanglement is utilized to purify the two-particle polarization-entangled state. The bit-...
Dynamical enhancement of spatial entanglement in massive particles
Dynamical enhancement spatial entanglement massive particles
2010/10/20
We discuss dynamical enhancement of entanglement in a driven Bose-Hubbard model and find
an enhancement of two orders of magnitude which is robust against fluctuations in experimental
parameters.
Spatial entanglement using quantum walk on many body system
Spatial entanglement quantum body system
2010/4/7
Evolution of many particles on a one dimensional lattice subjected to quantum walk can cause spatial entanglement in the lattice position which can be exploited for quantum information/communication p...
