Resource-efficient digital characterization and control of classical non-Gaussian noise
Wenzheng Dong, Gerardo A. Paz-Silva, Lorenza Viola
We show the usefulness of frame-based characterization and control [PRX Quantum 2, 030315 (2021)] for non-Markovian open quantum systems subject to classical non-Gaussian dephasing…
Dynamically corrected gates from geometric space curves
Edwin Barnes, Fernando A. Calderon-Vargas, Wenzheng Dong +3
Quantum information technologies demand highly accurate control over quantum systems. Achieving this requires control techniques that perform well despite the presence of decoherin…
Doubly geometric quantum control
Wenzheng Dong, Fei Zhuang, Sophia E. Economou +1
In holonomic quantum computation, single-qubit gates are performed using driving protocols that trace out closed loops on the Bloch sphere, making them robust to certain pulse erro…
Precise high-fidelity electron-nuclear spin entangling gates in NV centers via hybrid dynamical decoupling sequences
Wenzheng Dong, F. A. Calderon-Vargas, Sophia E. Economou
Color centers in solids, such as the nitrogen-vacancy center in diamond, offer well-protected and well-controlled localized electron spins that can be employed in various quantum t…
