Query: Robust quantum control for the manipulation of solid-state spins   Robust and high-fidelity control of electron spins in solids is the
cornerstone for facilitating applications of solid-state spins in quantum
information processing and quantum sensing. However, precise control of spin
systems is always challenging due to the presence of a variety of noises
originating from the environment and control fields. Herein, noise-resilient
quantum gates, designed with robust optimal control (ROC) algorithms, are
demonstrated experimentally with nitrogen-vacancy (NV) centers in diamond to
realize tailored robustness against detunings and Rabi errors simultaneously.
In the presence of both 10% off-resonant detuning and deviation of a Rabi
frequency, we achieve an average single-qubit gate fidelity of up to 99.97%.
Our experiments also show that, ROCbased multipulse quantum sensing sequences
can suppress spurious responses resulting from finite widths and imperfections
of microwave pulses, which provides an efficient strategy for enhancing the
performance of existing multipulse quantum sensing sequences.
