Atomic clock transitions in silicon-based spin qubits
Gary Wolfowicz, Alexei M. Tyryshkin, Richard E. George +7
A major challenge in using spins in the solid state for quantum technologies is protecting them from sources of decoherence. This can be addressed, to varying degrees, by improving…
Coherent spin control by electrical manipulation of the magnetic anisotropy
Richard E George, James P Edwards, Arzhang Ardavan
High-spin paramagnetic manganese defects in polar piezoelectric zinc oxide exhibit a simple almost axial anisotropy and phase coherence times of the order of a millisecond at low t…
Geometric Phase Gates with Adiabatic Control in Electron Spin Resonance
Hua Wu, Erik M. Gauger, Richard E. George +8
High-fidelity quantum operations are a key requirement for fault-tolerant quantum information processing. In electron spin resonance, manipulation of the quantum spin is usually ac…
Decoherence mechanisms of 209Bi donor electron spins in isotopically pure 28Si
Gary Wolfowicz, Stephanie Simmons, Alexei M. Tyryshkin +8
Bismuth (209Bi) is the deepest Group V donor in silicon and possesses the most extreme characteristics such as a 9/2 nuclear spin and a 1.5 GHz hyperfine coupling. These lead to se…
Opening up the Quantum Three-Box Problem with Undetectable Measurements
Richard E. George, Lucio Robledo, Owen Maroney +7
One of the most striking features of quantum mechanics is the profound effect exerted by measurements alone. Sophisticated quantum control is now available in several experimental…
Electron spin coherence and electron nuclear double resonance of Bi donors in natural Si
Richard E. George, Wayne Witzel, H. Riemann +4
Donors in silicon hold considerable promise for emerging quantum technologies, due to the their uniquely long electron spin coherence times. Bi donors in silicon differ from P and…
