Identical Quantum Particles as Potential Parts

Philip Goyal·Mar 25, 2026

The mathematical rules used to handle systems of identical quantum particles bring into question whether the elementary constituents of matter, such as electrons, have the fundamental characteristics of persistence and reidentifiability that are usua...

Precision bounds for frequency estimation under collective dephasing and open-loop control

Francisco Riberi, Gerardo Paz-Silva, Lorenza Viola·Mar 25, 2026

Dephasing noise is a ubiquitous source of decoherence in current atomic sensors. We address the problem of entanglement-assisted frequency estimation subject to classical dephasing noise with full spatial correlations (collective) and arbitrary tempo...

Quantum photonic neural networks in time

Ivanna M. Boras Vazquez, Jacob Ewaniuk, Nir Rotenberg·Mar 25, 2026

We introduce the architecture and timing algorithm to realize a time-bin-encoded quantum photonic neural network (QPNN): a reconfigurable nonlinear photonic circuit inspired by the brain and trained to process quantum information. Unlike the typical ...

The quantum harmonic oscillator on a circle -- fragmentation of the algebraic method

Daniel Burgarth, Paolo Facchi·Mar 24, 2026

A quantum particle on a circle in a quadratic potential exhibits a spectrum that is not harmonic, despite having all algebraic properties of the quantum harmonic oscillator. This raises the question where the usual algebraic argument -- implying inte...
