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…
Protecting a diamond quantum memory by charge state control
Matthias Pfender, Nabeel Aslam, Patrick Simon +17
In recent years, solid-state spin systems have emerged as promising candidates for quantum information processing (QIP). Prominent examples are the Nitrogen-Vacancy (NV) center in…
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…
Towards a room-temperature spin quantum bus in diamond via optical spin injection, transport and detection
Marcus W. Doherty, Carlos A. Meriles, Audrius Alkauskas +3
Diamond is a proven solid-state platform for spin-based quantum technology. The nitrogen-vacancy (NV) center in diamond has been used to realize small-scale quantum information pro…
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…
Readout and control of a single nuclear spin with a meta-stable electron spin ancilla
Sang-Yun Lee, Matthias Widmann, Torsten Rendler +12
Electron and nuclear spins associated with point defects in insulators are promising systems for solid state quantum technology. While the electron spin usually is used for readout…
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…
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…
Towards T1-limited magnetic resonance imaging using Rabi beats
H. Fedder, F. Dolde, F. Rempp +4
Two proof-of-principle experiments towards T1-limited magnetic resonance imaging with NV centers in diamond are demonstrated. First, a large number of Rabi oscillations is measured…
