QUROPE Quantum Information Processing and Communication in Europe

Quantum materials processed by non-equilibrium methods

 A. Research topics

• Si/Ge-based superconducting circuits
• Defect engineering in SiC for quantum spintronics
• Nanostructures for single photon emitters and receivers
• Chalcogen-hyperdoped nanowires for quantum sensors

B. Non-equilibrium methods

• Thermal processing by millisecond flash lamp or nanosecond pulsed laser
• Energetic particle irradiation using ions/electrons
• Isotopically pure doping by ion implantation
