Self-healing of Trotter error in digital adiabatic state preparation
Lucas K. Kovalsky, Fernando A. Calderon-Vargas, Matthew D. Grace +4
Adiabatic time evolution can be used to prepare a complicated quantum many-body state from one that is easier to synthesize and Trotterization can be used to implement such an evol…
Quantum circuit debugging and sensitivity analysis via local inversions
Fernando A. Calderon-Vargas, Timothy Proctor, Kenneth Rudinger +1
As the width and depth of quantum circuits implemented by state-of-the-art quantum processors rapidly increase, circuit analysis and assessment via classical simulation are becomin…
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…
Fast high-fidelity single-qubit gates for flip-flop qubits in silicon
Fernando A. Calderon-Vargas, Edwin Barnes, Sophia E. Economou
The flip-flop qubit, encoded in the states with antiparallel donor-bound electron and donor nuclear spins in silicon, showcases long coherence times, good controllability, and, in…
An adaptive quantum approximate optimization algorithm for solving combinatorial problems on a quantum computer
Linghua Zhu, Ho Lun Tang, George S. Barron +4
The quantum approximate optimization algorithm (QAOA) is a hybrid variational quantum-classical algorithm that solves combinatorial optimization problems. While there is evidence s…
