Deterministic linear-optical computing with symmetry-based qubits
David S. Simon, Christopher R. Schwarze, Anthony D. Manni +2
A particular type of linear optical multiport, the Grover four-port, has previously been shown to couple the spatial symmetry of a photon to its direction of travel. It is shown he…
Strain sensitivity enhancement in a Grover-Michelson interferometer
Anthony D. Manni, Christopher R. Schwarze, David S. Simon +2
The Michelson interferometric phase detection resolution can be enhanced by replacing conventional beam splitters with novel directionally unbiased four-port scatterers, such as Gr…
Next-generation interferometry with gauge-invariant linear optical scatterers
Christopher R. Schwarze, Anthony D. Manni, David S. Simon +2
Measurement technology employing optical interference phenomena such as a fringe pattern or frequency shift has been evolving for more than a century. The systems are being designe…
Scalar computational primitives with perturbative phase interferometry
Christopher R. Schwarze, Anthony D. Manni, David S. Simon +1
We describe how weak phase modulations applied to classical coherent light in specially modified linear interferometers can be used to perform primitive computational tasks. Instea…
Grover-Sagnac interferometer
Christopher R. Schwarze, Anthony D. Manni, David S. Simon +2
We demonstrate a nontraditional design of the Sagnac interferometer by replacing the commonly used beam splitter with a linear-optical Grover multiport. This substitution creates a…
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…
