High resolution, High contrast optical interface for defect qubits
Jong Sung Moon, Haneul Lee, Jin Hee Lee +10
Point defects in crystals provide important building blocks for quantum applications. To initialize, control, and read-out their quantum states, an efficient optical interface for…
Spectrally stable defect qubits with no inversion symmetry for robust spin-to-photon interface
Péter Udvarhelyi, Roland Nagy, Florian Kaiser +3
Scalable spin-to-photon interfaces require quantum emitters with strong optical transition dipole moment and low coupling to phonons and stray electric fields. It is known that par…
High-fidelity spin and optical control of single silicon vacancy centres in silicon carbide
Roland Nagy, Matthias Niethammer, Matthias Widmann +14
Optically interfaced spins in the solid promise scalable quantum networks. Robust and reliable optical properties have so far been restricted to systems with inversion symmetry. He…
Quantum properties of dichroic silicon vacancies in silicon carbide
Roland Nagy, Matthias Widmann, Matthias Niethammer +12
The controlled generation and manipulation of atom-like defects in solids has a wide range of applications in quantum technology. Although various defect centres have displayed pro…
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…
