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…
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…
Deviations from Geodesic Evolutions and Energy Waste on the Bloch Sphere
Leonardo Rossetti, Carlo Cafaro, Paul M. Alsing
In optimal quantum-mechanical evolutions, motion can occur along non-predetermined paths of shortest length in an optimal time. Alternatively, optimal evolutions can happen along p…
Frequency auto-homogenization using group-velocity-matched downconversion
Dylan Heberle, Christopher C. Tison, James Schneeloch +4
With the stability of integrated photonics at network nodes and the advantages of photons as flying qubits, photonic quantum information processing (PQIP) makes quantum networks in…
