Fast high-fidelity single-shot readout of spins in silicon using a single-electron box
G. A. Oakes, V. N. Ciriano-Tejel, D. Wise +18
Three key metrics for readout systems in quantum processors are measurement speed, fidelity and footprint. Fast high-fidelity readout enables mid-circuit measurements, a necessary…
Quantum Dot-Based Parametric Amplifiers
Laurence Cochrane, Theodor Lundberg, David J. Ibberson +8
Josephson parametric amplifiers (JPAs) approaching quantum-limited noise performance have been instrumental in enabling high fidelity readout of superconducting qubits and, recentl…
Non-reciprocal Pauli Spin Blockade in a Silicon Double Quantum Dot
Theodor Lundberg, David J. Ibberson, Jing Li +12
Spin qubits in gate-defined silicon quantum dots are receiving increased attention thanks to their potential for large-scale quantum computing. Readout of such spin qubits is done…
Spin readout of a CMOS quantum dot by gate reflectometry and spin-dependent tunnelling
V. N. Ciriano-Tejel, M. A. Fogarty, S. Schaal +8
Silicon spin qubits are promising candidates for realising large scale quantum processors, benefitting from a magnetically quiet host material and the prospects of leveraging the m…
Large dispersive interaction between a CMOS double quantum dot and microwave photons
David J. Ibberson, Theodor Lundberg, James A. Haigh +11
We report fast charge state readout of a double quantum dot in a CMOS split-gate silicon nanowire transistor via the large dispersive interaction with microwave photons in a lumped…
A Spin Quintet in a Silicon Double Quantum Dot: Spin Blockade and Relaxation
Theodor Lundberg, Jing Li, Louis Hutin +12
Spins in gate-defined silicon quantum dots are promising candidates for implementing large-scale quantum computing. To read the spin state of these qubits, the mechanism that has p…
Low-temperature tunable radio-frequency resonator for sensitive dispersive readout of nanoelectronic devices
David J. Ibberson, Lisa A. Ibberson, Geoff Smithson +3
We present a sensitive, tunable radio-frequency resonator designed to detect reactive changes in nanoelectronic devices down to dilution refrigerator temperatures. The resonator in…
