Researchers Abel, Wasek, and Williams developed a continuous-variable quantum computing (CVQC) algorithm to simulate Berry’s phase using photonic quantum computers, demonstrating its viability for studying geometric quantum effects. The team showed CVQC can model charged particles with orbital angular momentum under adiabatically changing magnetic fields, using only passive linear-optical components like beam splitters and phase shifters. Experiments on Quandella’s Ascella platform confirmed Berry’s phase via interferometric measurements, proving the algorithm’s practicality in real-world photonic systems without requiring complex hardware. The study extends beyond adiabatic conditions, generalizing the framework to rapid non-adiabatic evolution while maintaining geometric phase robustness through symmetric error cancellation techniques. By concatenating Aharonov-Anandan cycles with opposing magnetic fields, the researchers engineered circuits where dynamical phases and errors cancel, isolating the geometric phase for enhanced precision.

Quantum Physics arXiv:2511.19598 (quant-ph) [Submitted on 24 Nov 2025] Title:Berry's phase on photonic quantum computers Authors:Steven Abel, Iwo Wasek, Simon Williams View a PDF of the paper titled Berry's phase on photonic quantum computers, by Steven Abel and 1 other authors View PDF HTML (experimental) Abstract:We formulate a continuous-variable quantum computing (CVQC) algorithm to study Berry's phase on photonic quantum computers. We demonstrate that CVQC allows the simulation of charged particles with orbital angular momentum under the influence of an adiabatically changing $\vec{B}$ field. Although formulated entirely in the CVQC setting, our construction uses only passive linear-optical operations (beam splitters and phase shifts), which act identically in single-photon photonic architectures. This enables experimental realisation on the Quandella Ascella platform, where we observe the Berry's phase phenomenon with interferometric measurement. We also generalise the framework to more rapid non-adiabatic evolution. By concatenating Aharonov-Anandan cycles for opposing magnetic fields we demonstrate that one can engineer a circuit in which dynamical phases and leading non-geometric errors cancel by symmetry, leaving the intrinsically robust geometric phase contribution.
