Quantum-Bath Decoherence of Hybrid Electron-Nuclear Spin Qubits
S. J. Balian
A major problem facing the realisation of scalable solid-state quantum computing is that of overcoming decoherence - the process whereby phase information encoded in a qubit is los…
Decoherence of electron spins in isotopically enriched silicon near Clock Transitions
J. E. Lang, R. Guichard, S. J. Balian +1
Despite the importance of isotopically purified samples in current experiments, there have been few corresponding studies of spin qubit decoherence using full quantum bath calculat…
Keeping a spin qubit alive in natural silicon: Comparing optimal working points and dynamical decoupling
Setrak J. Balian, Ren-Bao Liu, T. S. Monteiro
There are two distinct techniques of proven effectiveness for extending the coherence lifetime of spin qubits in environments of other spins. One is dynamical decoupling, whereby t…
Decoherence of nuclear spins in the "frozen core" of an electron spin
R. Guichard, S. J. Balian, G. Wolfowicz +2
Hybrid qubit systems combining electronic spins with nearby ("proximate") nuclear spin registers offer a promising avenue towards quantum information processing, with even multi-sp…
Quantum bath-driven decoherence of mixed spin systems
S. J. Balian, Gary Wolfowicz, John J. L. Morton +1
The decoherence of mixed electron-nuclear spin qubits is a topic of great current importance, but understanding is still lacking: while important decoherence mechanisms for spin qu…
Measuring central-spin interaction with a spin bath by pulsed ENDOR: Towards suppression of spin diffusion decoherence
S. J. Balian, M. B. A. Kunze, M. H. Mohammady +4
We present pulsed electron-nuclear double resonance (ENDOR) experiments which enable us to characterize the coupling between bismuth donor spin qubits in Si and the surrounding spi…
Quantum control of hybrid nuclear-electronic qubits
Gavin W. Morley, Petra Lueders, M. Hamed Mohammady +6
Pulsed magnetic resonance is a wide-reaching technology allowing the quantum state of electronic and nuclear spins to be controlled on the timescale of nanoseconds and microseconds…
