Logarithmic Subdiffusion from a Damped Bath Model
Thomas Guff, Andrea Rocco
A damped oscillator heat bath model is a modification of the standard heat bath model, wherein each bath oscillator itself has a Markovian coupling to its own heat bath [1]. We mod…
Emergence of Opposing Arrows of Time in Open Quantum Systems
Thomas Guff, Chintalpati Umashankar Shastry, Andrea Rocco
Deriving an arrow of time from time-reversal symmetric microscopic dynamics is a fundamental open problem in many areas of physics, ranging from cosmology, to particle physics, to…
Optimal Fidelity Witnesses for Gravitational Entanglement
Thomas Guff, Nicolas Boulle, Igor Pikovski
Optomechanical systems open new possibilities in fundamental research at the interface between quantum information and gravity. Recently, an ambitious experimental proposal was sug…
Limits on inference of gravitational entanglement
Yue Ma, Thomas Guff, Gavin Morley +2
Combining gravity with quantum mechanics remains one of the biggest challenges of physics. In the past years, experiments with opto-mechanical systems have been proposed that may g…
Quantum State Discrimination as Bayesian Experimental Design
Thomas Guff, Yuval R. Sanders, Nathan A. McMahon +1
We show that quantum state discrimination sits neatly in the framework of Bayesian experimental design. In this setting, the two main branches of quantum state discrimination (mini…
A Resource Theory of Quantum Measurements
Thomas Guff, Nathan A. McMahon, Yuval R. Sanders +1
Resource theories are broad frameworks that capture how useful objects are in performing specific tasks. In this paper we devise a formal resource theory quantum measurements, focu…
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…
Post-Newtonian gravitational effects in quantum interferometry
Aharon Brodutch, Alexei Gilchrist, Thomas Guff +2
We investigate general properties of optical interferometry in stationary spacetimes and apply the obtained results focusing on quantum-optical experiments in near-Earth environmen…
