Ten-Second Electron-Spin Coherence in Isotopically Engineered Diamond
Takashi Yamamoto, H. Benjamin van Ommen, Kai-Niklas Schymik +7
Solid-state spin defects are a promising platform for quantum networks. A key requirement is to combine long ground-state spin-coherence times with a coherent optical transition fo…
First Determination of Level Structure of an -Shell Hypernucleus,
S. B. Yang, J. K. Ahn, Y. Akazawa +45
We report on the first observation of rays emitted from an -shell hypernucleus, . The energy spacing between the ground state doublet, and …
Isotopic identification of engineered nitrogen-vacancy spin qubits in ultrapure diamond
T. Yamamoto, S. Onoda, T. Ohshima +15
Nitrogen impurities help to stabilize the negatively-charged-state of NV in diamond, whereas magnetic fluctuations from nitrogen spins lead to decoherence of NV qubits. It…
Strongly Coupled Diamond Spin Qubits by Molecular Nitrogen Implantation
Takashi Yamamoto, Christoph Müller, Liam P. McGuinness +7
Ionized nitrogen molecules (N) are used as efficient point sources for creating NV pairs in diamond with nanoscale spatial separation and up to 55 kHz magnetic c…
Extending spin coherence times of diamond qubits by high temperature annealing
T. Yamamoto, T. Umeda, K. Watanabe +14
Spins of negatively charged nitrogen-vacancy (NV) defects in diamond are among the most promising candidates for solid-state qubits. The fabrication of quantum devices containi…
Statistical investigations on nitrogen-vacancy center creation
Denis Antonov, Timo Häußermann, Andrew Aird +10
Experiments show that shallow nitrogen implantations (<10keV) result in a negatively charged nitrogen-vacancy center (NV-) yield of 0.01-0.1%. The most succesful technique for intr…
Broadband Excitation by Chirped Pulses: Application to Single Electron Spins in Diamond
I. Niemeyer, J. H. Shim, J. Zhang +9
Pulsed excitation of broad spectra requires very high field strengths if monochromatic pulses are used. If the corresponding high power is not available or not desirable, the pulse…
Experimental implementation of assisted quantum adiabatic passage in a single spin
Jingfu Zhang, Jeong Hyun Shim, Ingo Niemeyer +8
Quantum adiabatic passages can be greatly accelerated by a suitable control field, called a counter-diabatic field, which varies during the scan through resonance. Here, we impleme…
Electron spin resonance detected by a superconducting qubit
Y. Kubo, I. Diniz, C. Grezes +14
A new method for detecting the magnetic resonance of electronic spins at low temperature is demonstrated. It consists in measuring the signal emitted by the spins with a supercondu…
