Quantum optimal control, a toolbox for devising and implementing the shapes of external
fields that accomplish given tasks in the operation of a quantum device in the best way …

Nitrogen-vacancy (NV) centers in diamond have recently emerged as a unique platform for
fundamental studies in quantum information and nanoscience. The special properties of …

The detection of ensembles of spins under ambient conditions has revolutionized the
biological, chemical and physical sciences through magnetic resonance imaging and …

We demonstrate a substantial improvement in the spin-exchange gate using symmetric
control instead of conventional detuning in GaAs spin qubits, up to a factor of six increase in …

Quantum process tomography is a necessary tool for verifying quantum gates and
diagnosing faults in architectures and gate design. We show that the standard approach of …

We experimentally demonstrate single-spin magnetometry with multipulse sensing
sequences. The use of multipulse sequences can greatly increase the sensing time per …

The study of individual quantum systems in solids, for use as quantum bits (qubits) and
probes of decoherence, requires protocols for their initialization, unitary manipulation, and …

Semiconductor spin qubits have recently seen major advances in coherence time and
control fidelities, leading to a single-qubit performance that is on par with other leading qubit …

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 …

Single-qubit operations on singlet-triplet qubits in GaAs double quantum dots have not yet
reached the fidelities required for fault-tolerant quantum information processing …
