Squeezing the angular momentum of an ensemble of complex multi-level atoms
Daniel Hemmer, Enrique Montano, Ben Q. Baragiola +4
Squeezing of collective atomic spins has been shown to improve the sensitivity of atomic clocks and magnetometers to levels significantly below the standard quantum limit. In most…
Power and Efficiency of a Thermal Engine with a Coherent Bath
Thomas Guff, Shakib Daryanoosh, Ben Q. Baragiola +1
We consider a quantum engine driven by repeated weak interactions with a heat bath of identical three-level atoms. This model was first introduced by Scully et al. [Science, 2003],…
Quantum master equations for entangled qubit environments
Shakib Daryanoosh, Ben Q. Baragiola, Thomas Guff +1
We study the Markovian dynamics of a collection of n quantum systems coupled to an irreversible environmental channel consisting of a stream of n entangled qubits. Within the frame…
Generating nonclassical states of motion using spontaneous emission
Ben Q. Baragiola, Jason Twamley
Nonclassical motional states of matter are of interest both from a fundamental perspective but also for their potential technological applications as resources in various quantum p…
