Spin decoherence and electron spin bath noise of a nitrogen-vacancy center in diamond
Zhi-Hui Wang, Susumu Takahashi
We theoretically investigate spin decoherence of a single nitrogen-vacancy (NV) center in diamond. Using the spin coherent state P-representation method, coherence evolution of the…
Comparison of dynamical decoupling protocols for a nitrogen-vacancy center in diamond
Zhi-Hui Wang, G. de Lange, D. Riste +2
We perform a detailed theoretical-experimental study of the dynamical decoupling (DD) of the nitrogen-vacancy (NV) center in diamond. We investigate the DD sequences applied to sup…
Controlling the quantum dynamics of a mesoscopic spin bath in diamond
G. de Lange, T. van der Sar, M. S. Blok +3
Understanding and mitigating decoherence is a key challenge for quantum science and technology. The main source of decoherence for solid-state spin systems is the uncontrolled spin…
Time-optimal rotation of a spin 1/2: application to the NV center spin in diamond
Zhi-Hui Wang, V. V. Dobrovitski
We study the applicability of the time optimal bang-bang control designed for spin-1/2 [U. Boscain and P. Mason, J. Math. Phys. {\bf 47}, 062101 (2006)] to the rotation of the elec…
Aperiodic dynamical decoupling sequences in presence of pulse errors
Zhi-Hui Wang, V. V. Dobrovitski
Dynamical decoupling (DD) is a promising tool for preserving the quantum states of qubits. However, small imperfections in the control pulses can seriously affect the fidelity of d…
Dynamical Decoupling in the Presence of Realistic Pulse Errors
A. M. Tyryshkin, Zhi-Hui Wang, Wenxian Zhang +4
One of the most significant hurdles to be overcome on the path to practical quantum information processors is dealing with quantum errors. Dynamical decoupling is a particularly pr…
