Sensing Quantum Vacuum Fluctuations with Non-Gaussian Electronic Noise
arXiv:2404.06594 · doi:10.1103/PhysRevLett.134.166301
Abstract
The statistics of electron transport in a quantum conductor is affected by fluctuations of its voltage bias. Here we show experimentally how a third order correlation in the electromagnetic field arises from the noise of a tunnel junction in the microwave domain being modulated by the vacuum fluctuations generated by a resistor at ultralow temperature. This provides a way to measure the vacuum fluctuations experienced by the junction, not offset by the unavoidable noise added by the detection setup.
