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…
