A family of exact eigenstates for a single trapped ion interacting with a laser field
H. Moya-Cessa, D. Jonathan, P. L. Knight
We show that, under certain combinations of the parameters governing the interaction of a harmonically trapped ion with a laser beam, it is possible to find one or more exact eigen…

Entanglement induced by a single-mode heat environment
M. S. Kim, J. Lee, D. Ahn +1
A thermal field, which frequently appears in problems of decoherence, provides us with minimal information about the field. We study the interaction of the thermal field and a quan…

Subsystem Purity as an Enforcer of Entanglement
S. Bose, I. Fuentes-Guridi, P. L. Knight +1
We show that entanglement can always arise in the interaction of an arbitrarily large system in any mixed state with a single qubit in a pure state. This small initial purity is en…
