Photonic qubit encoding interconversion for heterogeneous quantum networking

Vedansh Nehra, Richard J. Birrittella, Christopher C. Tison +10

Quantum information processing, communication, and sensing networks are being developed with various qubit platforms that use different encoding schemes. Connecting quantum network…

Lissajous coherent states via projection

Errico J. Russo, James Schneeloch, Edwin E. Hach +3

We construct stationary coherent states concentrated on Lissajous figures of the isotropic and anisotropic harmonic oscillators, the latter having coprime frequencies, by projectin…

Multiphoton Interference with a symmetric SU(N) beam splitter and the generalization of the extended Hong-Ou-Mandel effect

Paul M. Alsing, Richard J. Birrittella, Peter L. Kaulfuss

We examine multiphoton interference with a symmetric beam splitter , an extension of features of the 50/50 beam splitter extended Hong-Ou-Mandel (eHOM) effect,…

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…

An examination of the extended Hong-Ou-Mandel effect and considerations for experimental detection

Paul M. Alsing, Richard J. Birrittella

In recent works we have explored a multi-photon extension of the celebrated two-photon Hong-Ou-Mandel (HOM) effect in which the quantum amplitudes for a two-photon input to a lossl…

The Hong-Ou-Mandel effect is really odd

Paul M. Alsing, Richard J. Birrittella, Christopher C. Gerry +2

When quantum state amplitudes interfere, surprising non-classical features emerge which emphasis the roles of indistinguishability and discreteness in quantum mechanics. A famous e…
