Coherent Dark State Formation of a Lead-Vacancy Spin Qubit in Diamond
Yiyang Chen, Koyo Hirai, Tzyy Zheng Neo +7
A lead-vacancy (PbV) center in diamond exhibits coherent emission above the liquid helium temperature, making it highly attractive for quantum network applications. Here, we report…
Optical charge state manipulation of lead-vacancy centers in diamond
Yiyang Chen, Yoshiyuki Miyamoto, Eiki Ota +5
Group-IV vacancy centers in diamond exhibit excellent optical and spin coherence properties, making them highly promising and scalable spin qubit candidates. Since only specific ch…
Narrow Inhomogeneous Distribution and Charge State Stabilization of Lead-Vacancy Centers in Diamond
Ryotaro Abe, Peng Wang, Takashi Taniguchi +4
Lead-vacancy (PbV) centers in diamond with a large ground state splitting are expected to be a building block of quantum network nodes. Due to the heaviness of the Pb atom, it is c…
Charge state transition of spectrally stabilized tin-vacancy centers in diamond
Keita Ikeda, Yiyang Chen, Peng Wang +5
Solid-state quantum emitters are an important platform for quantum information processing. The fabrication of the emitters with stable photon frequency and narrow linewidth is a fu…
