Quantum control with noisy fields: computational complexity vs. sensitivity to noise
S. Kallush, M. Khasin, R. Kosloff
A closed quantum system is defined as completely controllable if an arbitrary unitary transformation can be executed using the available controls. In practice, control fields are a…
Algorithm for simulation of quantum many-body dynamics using dynamical coarse graining
M. Khasin, R. Kosloff
An algorithm for simulation of quantum many-body dynamics having su(2) spectrum-generating algebra is developed. The algorithm is based on the idea of dynamical coarse-graining. Th…
Efficient simulation of quantum evolution using dynamical coarse-graining
M. Khasin, R. Kosloff
A novel scheme to simulate the evolution of a restricted set of observables of a quantum system is proposed. The set comprises the spectrum-generating algebra of the Hamiltonian. T…
Negativity as a distance from a separable state
M. Khasin, R. Kosloff, D. Steinitz
The computable measure of the mixed-state entanglement, the negativity, is shown to admit a clear geometrical interpretation, when applied to Schmidt-correlated (SC) states: the ne…
The rise and fall of quantum and classical correlations in open-system dynamics
Michael Khasin, Ronnie Kosloff
Interacting quantum systems evolving from an uncorrelated composite initial state generically develop quantum correlations -- entanglement. As a consequence, a local description of…
On the temperature dependence of the interaction-induced entanglement
Michael Khasin, Ronnie Kosloff
Both direct and indirect weak nonresonant interactions are shown to produce entanglement between two initially disentangled systems prepared as a tensor product of thermal states,…
