Controlling phonon entanglement and squeezing via one- and two-phonon interference
Controlling phonon entanglement squeezing two-phonon interference
2010/11/19
When ultrafast laser pulse strikes the crystal with a van Hove singularity in the phonon density of states, it creates a pair of anti-correlated in wave vector acoustic phonons. As a result, the atomi...
Entanglement-Enhanced Classical Communication over a Noisy Classical Channel
Entanglement-Enhanced Classical Communication Noisy Classical Channel
2010/11/5
We present and experimentally demonstrate a communication protocol that employs shared entanglement to reduce errors when sending a bit over a particular noisy classical channel. Specifically, it is s...
Efficient entanglement distribution for quantum communication against collective noise
Efficient entanglement distribution quantum communication against collective noise
2010/10/29
We present an efficient faithful entanglement distribution scheme for quantum communication against collective noise. Its setup is composed of polarizing beam splitters, half wave plates, polarization...
