Quantum stochastic resonance in a single-photon emitter

H. Mannel, J. Zöllner, E. Kleinherbers +8

Stochastic resonance is a phenomenon in which fluctuations enhance an otherwise weak signal. It has been found in many different systems in paleoclimatology, biology, medicine, and…

MoSi Superconducting Nanowire Single-Photon Detectors on GaAs for On-Chip Integration

M. Erbe, R. Berrazouane, S. Geyer +8

We report on MoSi-based superconducting nanowire single-photon detectors on a gallium arsenide substrate. MoSi deposited on a passivated GaAs surface has the same critical temperat…

Electrical resistance associated with the scattering of optically oriented electrons in n-GaAs

M. D. Ragoza, N. V. Kozyrev, S. V. Nekrasov +5

In a bulk GaAs crystal, an unusual magnetoresistance effect, which takes place when a spin-polarized current flows through the sample, was detected. Under conditions of optical pum…

Making Every Photon Count: A Quantum Polyspectra Approach to the Dynamics of Blinking Quantum Emitters at Low Photon Rates Without Binning

M. Sifft, A. Kurzmann, J. Kerski +6

The blinking statistics of quantum emitters and their corresponding Markov models play an important role in high resolution microscopy of biological samples as well as in nano-opto…

Extending the time of coherent optical response in ensemble of singly-charged InGaAs quantum dots

A. N. Kosarev, A. V. Trifonov, I. A. Yugova +10

The ability to extend the time scale of the coherent optical response from large ensembles of quantum emitters is highly appealing for applications in quantum information devices.…
