A Single Atom in Front of a Mirror is a Universal Reservoir Computer

Peter J. Ehlers, Phi Hung Nguyen, Kanu Sinha +4

Universal approximation in reservoir computing is typically associated with a class of reservoirs. We show that universality can be associated with a single reservoir, considering…

Computational Superiority of Non-Markovian Kerr Feedback in Continuous-Variable Quantum Reservoir Computing

Daniel Soh

A linear optical medium can delay, mix, and superpose light, but never make two pulses multiply: multiplication is nonlinear, and a linear system has no such operation. This roots…

Quantum-Limited Acoustoelectric Amplification in a Piezoelectric-2DEG Heterostructure

Eric Chatterjee, Daniel Soh, Matt Eichenfield

We provide a quantum mechanical description of phonon amplification in a heterostructure consisting of a two-dimensional electron gas (2DEG) stacked on top of a piezoelectric mater…
