Directionally-unbiased Linear Multiports: Quantum Interference and Registration of Multi-Dimensional Rotation
David S. Simon, Christopher R. Schwarze, Alexander V. Sergienko · Quantum 2.0 Conference and Exhibition · 2024
We describe a quantum walk in which photons remain clustered together as they walk along a chain. This effect can be used to construct higher-dimensional quantum Sagnac interferometers that measure rotaƟons about three axes simultaneously.
