Operating a contextual Stern-Gerlach apparatus
Th. K. Mavrogordatos
We propose a contextual cavity/circuit QED analogue and extension of the Stern-Gerlach experiment, where the pseudo-spin of a two-state `atomic' transition plays the role of the ``…
Decoherence of Schrödinger cat states in light of wave/particle duality
Th. K. Mavrogordatos
We challenge the standard picture of decohering Schrödinger cat states as an ensemble average obeying a Lindblad master equation, brought about locally from an irreversible intera…
Statistical properties of quantum jumps between macroscopic states of light: reading an operational coherence record
Th. K. Mavrogordatos
We propose an experimental apparatus to reveal the quantum coherence manifested in downward quantum jumps of amplitude bistability. The underlying coherent superposition of macrosc…
Quantum jumps in amplitude bistability: Tracking a coherent and invertible state localization
Th. K. Mavrogordatos
We investigate the nature of quantum jumps occurring between macroscopic metastable states of light in the open driven Jaynes-Cummings model. We find that, in the limit of zero spo…
Wave/particle duality in monitored Jaynes--Cummings resonances
Th. K. Mavrogordatos
We operationally uncover aspects of wave/particle duality for the open driven Jaynes-Cummings (JC) model in its strong-coupling limit. We lay special emphasis on the vacuum Rabi re…
Telling different unravelings apart via nonlinear quantum-trajectory averages
Eloy Piñol, Th. K. Mavrogordatos, Dustin Keys +7
The Gorini-Kossakowski-Sudarshan-Lindblad master equation (ME) governs the density matrix of open quantum systems (OQSs). When an OQS is subjected to weak continuous measurement, i…
