Matrix product states and the decay of quantum conditional mutual information
Pavel Svetlichnyy, Shivan Mittal, T. A. B. Kennedy
A uniform matrix product state defined on a tripartite system of spins, denoted by is shown to be an approximate quantum Markov chain when the size of subsystem denoted…
Fast generation of time-stationary spin-1 squeezed states by non-adiabatic control
Lin Xin, M. S. Chapman, T. A. B. Kennedy
A protocol for the creation of time-stationary squeezed states in a spin-1 Bose condensate is proposed. The method consists of a pair of controlled quenches of an external magnetic…
Anisotropies in the linear polarization of vacancy photoluminescence in diamond induced by crystal rotations and strong magnetic fields
D. Braukmann, V. P. Popov, E. R. Glaser +3
We study the linear polarization properties of the photoluminescence of the neutral and negatively charged nitrogen vacancies and neutral vacancies in diamond crystals as function…
Entanglement of neutral-atom chains by spin-exchange Rydberg interaction
Xiao-Feng Shi, F. Bariani, T. A. B. Kennedy
Conditions to achieve an unusually strong Rydberg spin-exchange interaction are investigated and proposed as a means to generate pairwise entanglement and realize a SWAP-like quant…
Dephasing dynamics of Rydberg atom spin waves
F. Bariani, Paul M. Goldbart, T. A. B. Kennedy
A theory of Rydberg atom interactions is used to derive analytical forms for the spin wave pair correlation function in laser-excited cold-atom vapors. This function controls the q…
Retrieval of multiple spin waves from a weakly excited, metastable atomic ensemble
F. Bariani, T. A. B. Kennedy
The emission of light from a multiply excited atomic ensemble is examined and it is shown how symmetric (spin-wave) and non-symmetric states of excitation radiate into spatially se…
