Opto-Electrical Detection of Donor Bound Excitons in Silicon-on-Insulator Substrate
A. Kanniainen, A. S. Kumar, A. Sammak +2
Spin of a donor bound electron in silicon has been shown to be a very coherent qubit system but lacks a coherent optical interface. There does, however, exist a donor bound exciton…
Millikelvin Si-MOSFETs for Quantum Electronics
Nikolai Yurttagül, Markku Kainlauri, Jan Toivonen +7
Large power consumption of silicon CMOS electronics is a challenge in very-large-scale integrated circuits and a major roadblock to fault-tolerant quantum computation. Matching the…
Strain effects in phosphorous bound exciton transitions in silicon
Teemu Loippo, Antti Kanniainen, Juha T. Muhonen
Donor spin states in silicon are a promising candidate for quantum information processing. One possible donor spin readout mechanism is the bound exciton transition that can be exc…
Roadmap for gallium arsenide spin qubits
Ferdinand Kuemmeth, Hendrik Bluhm
Gate-defined quantum dots in gallium arsenide (GaAs) have been used extensively for pioneering spin qubit devices due to the relative simplicity of fabrication and favourable elect…
Optimization of a solid-state electron spin qubit using Gate Set Tomography
Juan P. Dehollain, Juha T. Muhonen, Robin Blume-Kohout +8
State of the art qubit systems are reaching the gate fidelities required for scalable quantum computation architectures. Further improvements in the fidelity of quantum gates deman…
Breaking the rotating wave approximation for a strongly-driven, dressed, single electron spin
Arne Laucht, Stephanie Simmons, Rachpon Kalra +10
We investigate the dynamics of a strongly-driven, microwave-dressed, donor-bound electron spin qubit in silicon. A resonant oscillating magnetic field is used to dress the el…
