Squeezing Every Drop of Fresh Water from Waste Brine
Squeezing Every Drop Fresh Water Waste Brine

2017/7/21
Engineers at the University of California, Riverside have developed a new way to recover almost 100 percent of the water from highly concentrated salt solutions. The system will alleviate water shorta...

The relationship between orientation-to-alignment conversion (a form of atomic polarization evolution induced by an electric eld) and the phenomenon of spin squeezing is demonstrated. A \stretched" s...
Finite-difference analysis for unsteady squeezing flow of a second grade fluid between circular plates
Non-Newtonian fluids Squeezing flow

2010/9/27
The unsteady two-dimensional flow of non-conducting, incompressible second grade fluid between two circular plates approaching or receding from each other symmetrically is studied. A similarity transf...
Controlling phonon entanglement and squeezing via one- and two-phonon interference
Controlling phonon entanglement squeezing two-phonon interference

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...
Would one rather store squeezing or entanglement in continuous variable quantum memories?

2010/11/5
Given two quantum memories for continuous variables (e.g., the collective pseudo-spin of two atomic ensembles) and the possibility to perform passive optical operations (typically beam-splitters) on t...
Spin Squeezing, Negative Correlations, and Concurrence in the Quantum Kicked Top Model
Spin Squeezing Negative Correlations Concurrence Quantum Kicked Top Model
font style='font-size:12px;'>
2010/10/29
We study spin squeezing, negative correlations, and concurrence in the quantum kicked top model. We prove that the spin squeezing and negative correlations are equivalent for spin systems with only sy...
Teleporting squeezing: Optimization using non-Gaussian resources
Teleporting squeezing non-Gaussian resources
font style='font-size:12px;'>
2010/10/21
We study the continuous-variable quantum teleportation of states, statistical moments of observables, and scale parameters such as squeezing. We investigate the problem both in ideal and imperfect Vai...
