From Quantum-Mechanical Acceleration Limits to Upper Bounds on Fluctuation Growth of Observables in Unitary Dynamics

Carlo Cafaro, Walid Redjem, Paul M. Alsing +2

Recently, the notion of a quantum acceleration limit has been proposed for any unitary time evolution of quantum systems governed by arbitrary nonstationary Hamiltonians. This limi…

Inertial-to-Rindler Coordinates, with applications to the Twin Paradox, Radar Time and the Unruh Temperature

Paul M. Alsing

In this work we formulate a two-parameter family of transformations in flat Minkowksi spacetime that smoothly interpolates between motion with constant initial/final velocity (iner…

Quantum Optical Inspired Models for Unitary Black Hole Evaporation

Paul M. Alsing

In this work, we describe optically inspired models for unitary black hole (BH) evaporation. The goal of these models are (i) to be operationally simple, (ii) approximately preserv…

Upper Bounds on Fluctuation Growths of Observables in Open Quantum Systems

Newshaw Bahreyni, Paul M. Alsing, Carlo Cafaro +2

The upper bounds for the rate of fluctuation growth of an observable in both open and closed quantum systems have been studied actively recently. In our recent work we showed that…

Telecommunications fiber-optic and free-space quantum local area networks at the Air Force Research Laboratory

Erin Sheridan, Nicholas J. Barton, Richard Birrittella +29

As quantum computing, sensing, timing, and networking technologies mature, quantum network testbeds are being deployed across the United States and around the world. To support the…

Microring resonator-based photonic circuit for faithfully heralding NOON states

Ryan Scott, Peter L. Kaulfuss, A. Matthew Smith +4

We have designed a Micro-Ring Resonator (MRR) based device that allows for the post-selection of high order NOON states via heralding. NOON states higher than cannot be gener…
