Dear All, Historically, experiments in quantum entanglement have been performed in the optical band and near IR/UV, unless you cool to cryogenic temperatures (milliKelvin), so the thermally generated photons don't swamp the entangled photon pairs.
However, receiver concepts exploiting radio astronomy receivers and digital correlators may be exploited to conduct entanglement experiments in the microwave or millimetre wave band at ambient temperature. The system concepts are discussed at: https://doi.org/10.1016/j.jmmm.2020.166435 This may enable a new outlet for radio astronomy receiver technology. Happy to exchange ideas on the subject. many thanks, Neil https://www.mmw-sensors.org<https://www.mmw-sensors.org/> "Before acting on this email or opening any attachments you should read the Manchester Metropolitan University email disclaimer available on its website http://www.mmu.ac.uk/emaildisclaimer " -- You received this message because you are subscribed to the Google Groups "casper@lists.berkeley.edu" group.
