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…
Designing arbitrary single-axis rotations robust against perpendicular time-dependent noise
Bikun Li, F. A. Calderon-Vargas, Junkai Zeng +1
Low-frequency time-dependent noise is one of the main obstacles on the road towards a fully scalable quantum computer. The majority of solid-state qubit platforms, from superconduc…
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…
Fast noise-resistant control of donor nuclear spin qubits in silicon
James Simon, F. A. Calderon-Vargas, Edwin Barnes +1
A high degree of controllability and long coherence time make the nuclear spin of a phosphorus donor in isotopically purified silicon a promising candidate for a quantum bit. Howev…
Microwave-based Arbitrary CPHASE Gates for Transmon Qubits
George S. Barron, F. A. Calderon-Vargas, Junling Long +2
Superconducting transmon qubits are of great interest for quantum computing and quantum simulation. A key component of quantum chemistry simulation algorithms is breaking up the ev…
Fast high-fidelity entangling gates for spin qubits in Si double quantum dots
F. A. Calderon-Vargas, George S. Barron, Xiu-Hao Deng +3
Implementing high-fidelity two-qubit gates in single-electron spin qubits in silicon double quantum dots is still a major challenge. In this work, we employ analytical methods to d…
