Spin Coherence During Optical Excitation of a Single NV Center in Diamond

G. D. Fuchs, A. L. Falk, V. V. Dobrovitski +1

We examine the quantum spin state of a single nitrogen-vacancy (NV) center in diamond at room temperature as it makes a transition from the orbital ground-state (GS) to the orbital…

Pointer States via Engineered Dissipation

Kaveh Khodjasteh, Viatcheslav V. Dobrovitski, Lorenza Viola

Pointer states are long-lasting high-fidelity states in open quantum systems. We show how any pure state in a non-Markovian open quantum system can be made to behave as a pointer s…

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…
