Transform-Limited Photon Emission From a Lead-Vacancy Center in Diamond Above 10 K
Peng Wang, Lev Kazak, Katharina Senkalla +9
Transform-limited photon emission from quantum emitters is essential for high-fidelity entanglement generation. In this study, we report the coherent optical property of a single n…
Germanium Vacancy in Diamond Quantum Memory Exceeding 20 ms
Katharina Senkalla, Genko Genov, Mathias H. Metsch +2
Negatively charged group-IV defects in diamond show great potential as quantum network nodes due to their efficient spin-photon interface. However, reaching sufficiently long coher…
Initialization and Readout of Nuclear Spins via negatively charged Silicon-Vacancy Center in Diamond
Mathias H. Metsch, Katharina Senkalla, Benedikt Tratzmiller +7
In this work, we demonstrate initialization and readout of nuclear spins via a negatively charged silicon-vacancy (SiV) electron spin qubit. Under Hartmann-Hahn conditions the elec…
Tin-Vacancy Quantum Emitters in Diamond
Takayuki Iwasaki, Yoshiyuki Miyamoto, Takashi Taniguchi +4
Tin-vacancy (SnV) color centers were created in diamond by ion implantation and subsequent high temperature annealing up to 2100 °C at 7.7 GPa. The first-principles calculation sug…
Optical and microwave control of germanium-vacancy center spins in diamond
Petr Siyushev, Mathias H. Metsch, Aroosa Ijaz +13
A solid-state system combining a stable spin degree of freedom with an efficient optical interface is highly desirable as an element for integrated quantum optical and quantum info…
Coherent properties of single rare-earth spin qubits
P. Siyushev, K. Xia, R. Reuter +8
Rare-earth-doped crystals are excellent hardware for quantum storage of optical information. Additional functionality of these materials is added by their waveguiding properties al…
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…
Low temperature optical characterization of near infrared single photon emitters in nanodiamonds
P. Siyushev, V. Jacques, I. Aharonovich +8
In this paper, we study the optical properties of single defects emitting in the near infrared in nanodiamonds at liquid helium temperature. The nanodiamonds are synthesized using…
Low temperature studies of the excited-state structure of Nitrogen-Vacancy color centers in diamond
A. Batalov, V. Jacques, F. Kaiser +7
We report a study of the 3E excited-state structure of single nitrogen-vacancy (NV) defects in diamond, combining resonant excitation at cryogenic temperatures and optically detect…
Coherence of single spins coupled to a nuclear spin bath of varying density
N. Mizuochi, P. Neumann, F. Rempp +9
The dynamics of single electron and nuclear spins in a diamond lattice with different 13C nuclear spin concentration is investigated. It is shown that coherent control of up to thr…
