Kinetic-inductance-limited reset time of superconducting nanowire photon counters
read the original abstract
We investigate the recovery of superconducting NbN-nanowire photon counters after detection of an optical pulse at a wavelength of 1550 nm, and present a model that quantitatively accounts for our observations. The reset time is found to be limited by the large kinetic inductance of these nanowires, which forces a tradeoff between counting rate and either detection efficiency or active area. Devices of usable size and high detection efficiency are found to have reset times orders of magnitude longer than their intrinsic photoresponse time.

Entanglement of two optical emitters mediated by a terahertz channel
Steady-state entanglement with concurrence above 0.9 is generated between optical emitters by optically tuning Rabi-split dressed states to couple via a THz channel and collective dissipation.
