Detecting photons with Rydberg atoms
Unlike all other quantum technology platforms, photonics encodes quantum information without noise at room temperature, without the need for high vacuum, pumping / cooling, or magnetic / electrical shielding. Frustratingly, these advantages must be sacrificed when high-efficiency photon counting is required, as >95% photo-detection efficiency is only available via superconducting photo-detector...
متن کاملDetecting Coherent Phonon Wave Effects in Superlattices Using Time - Domain
Superlattices (SLs), structures consisting of periodic layers of thin films of several angstroms to tens of nanometers thick, have unique electrical and thermal properties that make them well suited for applications in optoelectronics and as fundamental learning tools in the realm of thermoelectrics. One unique characteristic of SLs is their low thermal conductivity compared to a bulk material ...
متن کاملPhonon-assisted decoherence in the production of polarization-entangled photons in a single semiconductor quantum dot.
We theoretically investigate the production of polarization-entangled photons through the biexciton cascade decay in a single semiconductor quantum dot. In the intermediate state the entanglement is encoded in the polarizations of the first emitted photon and the exciton, where the exciton state can be effectively "measured" by the solid-state environment through the formation of a lattice dist...
متن کاملSearch for photons with
A search for ultra-high energy photons with energies above 1 EeV is performed using nine years of data collected by the Pierre Auger Observatory in hybrid operation mode. An unprecedented separation power between photon and hadron primaries is achieved by combining measurements of the longitudinal air-shower development with the particle content at ground measured by the fluorescence and surfac...
متن کاملBosonSampling with Lost Photons
BosonSampling is an intermediate model of quantum computation where linear-optical networks are used to solve sampling problems expected to be hard for classical computers. Since these devices are not expected to be universal for quantum computation, it remains an open question of whether any error-correction techniques can be applied to them, and thus it is important to investigate how robust ...
