Single Photon Transistor Mediated by Inter-State Rydberg Interaction
Hannes Gorniaczyk, Christoph Tresp, Johannes Schmidt +2
We report on the realization of an all-optical transistor by mapping gate and source photons into strongly interacting Rydberg excitations with different principal quantum numbers…
Sensing electric fields using single diamond spins
Florian Dolde, Helmut Fedder, Marcus W. Doherty +8
The ability to sensitively detect charges under ambient conditions would be a fascinating new tool benefitting a wide range of researchers across disciplines. However, most current…
Purcell-enhanced single-photon emission from nitrogen-vacancy centers coupled to a tunable microcavity
Hanno Kaupp, Thomas Hümmer, Matthias Mader +7
Optical microcavities are a powerful tool to enhance spontaneous emission of individual quantum emitters. However, the broad emission spectra encountered in the solid state at room…
Characterization of Electro-Optical Devices with Low Jitter Single Photon Detectors -- Towards an Optical Sampling Oscilloscope Beyond 100 GHz
Helmut Fedder, Steffen Oesterwind, Markus Wick +10
We showcase an optical random sampling scope that exploits single photon counting and apply it to characterize optical transceivers. We study single photon detectors with a jitter…
Magnetic criticality-enhanced hybrid nanodiamond-thermometer under ambient conditions
Ning Wang, Gang-Qin Liu, Weng-Hang Leong +10
Nitrogen vacancy (NV) centres in diamond are attractive as quantum sensors owing to their superb coherence under ambient conditions. However, the NV centre spin resonances are rela…
Dynamical Decoupling of a single electron spin at room temperature
Boris Naydenov, Florian Dolde, Liam T. Hall +5
Here we report the increase of the coherence time T of a single electron spin at room temperature by using dynamical decoupling. We show that the Carr-Purcell-Meiboom-Gill (CPM…
