Lukin. 2004. “Capacitive Coupling of Atomic Systems to Mesoscopic Conductors.” Physical Review Letters 92 (6). https://doi.org/10.1103/physrevlett.92.063601.0031-90071079-71141092-0145http://nrs.harvard.edu/urn-3:HUL.InstRepos:41467464We describe a technique that enables a strong, coherent coupling between isolated neutral atoms and mesoscopic conductors. The coupling is achieved by exciting atoms trapped above the surface of a superconducting transmission line into Rydberg states with large electric dipole moments that induce voltage fluctuations in the transmission line. Using a mechanism analogous to cavity quantum electrodynamics, an atomic state can be transferred to a long-lived mode of the fluctuating voltage, atoms separated by millimeters can be entangled, or the quantum state of a solid-state device can be mapped onto atomic or photonic states.en-USJournal Article2019-10-0310.1103/PhysRevLett.92.063601
