Experimental demonstration of a Grover-Michelson interferometer

Christopher R. Schwarze, David S. Simon, Anthony D. Manni +2

We present a low-resource and robust optical implementation of the four-dimensional Grover coin, a four-port linear-optical scatterer that augments the low dimensionality of a regu…

Single-photon description of the lossless optical Y coupler

Christopher R. Schwarze, Anthony D. Manni, David S. Simon +1

Using symmetry considerations, we derive a unitary scattering matrix for a three-port optical Y-coupler or Y-branch. The result is shown to be unique up to external phase shifts. U…

Exceptional points in SSH-like models with hopping amplitude gradient

David S. Simon, Christopher R. Schwarze, Abdoulaye Ndao +1

The Su-Schrieffer-Heeger (SSH) system is a popular model for exploring topological insulators and topological phases in one dimension. Recent interest in exceptional points has led…

Finite-element assembly approach of optical quantum walk networks

Christopher R. Schwarze, David S. Simon, Anthony D. Manni +2

We present a finite-element approach for computing the aggregate scattering matrix of a network of linear coherent scatterers. These might be optical scatterers or more general sca…

Tunable linear-optical phase amplification

Christopher R. Schwarze, David S. Simon, Abdoulaye Ndao +1

We combine lossless, phase-only transformations with fully-transmitting linear-optical scatterers to define the principle of linear-optical phase amplification. This enables a phys…
