Quantum Waveguides Confine Light With Potential And Kinetic Energy.

The scientists at the University of Paderborn have taken another step forward in the field of quantum research: for the first time they have demonstrated a cryogenic circuit (that is, one that operates under extremely cold conditions) that allows Light Quanta – also known as photons – to be controlled [...]

Quantum Waveguides Confine Light With Potential And Kinetic Energy.

A new quantum theoretical framework detailing microwave propagation within superconducting waveguides commonly used in solid-state quantum devices reveals a relationship between mode-specific dispersion, potential energy, and zero-point fluctuations, predicting lower quantum noise in certain transverse magnetic modes potentially advantageous for quantum information routing.
