Photon-recoil and laser-focusing limits to Rydberg gate fidelity

WebIn most situations, photon recoil heating is negligibly small for macroscopic objects, as the recoil energy ℏ2k2=ð2mÞ scales inversely with the object’s mass. Consequently, to observe this weak effect, the system has to be sufficiently well isolated. Specifically, the photon recoil rate has to be larger than the thermal decoherence rate. Webapproaches. It has been established that atom recoil in photon emission is inversely proportional to photon energy. The strongest recoil is characteristic of thermal low … scanning stage technology for exposure tools
