Comparing and correcting robustness metrics for quantum optimal control
Andrew T. Kamen, Samuel Fine, Bikrant Bhattacharyya +2
Control pulses that nominally optimize fidelity are sensitive to routine hardware drift and modeling errors. Robust quantum optimal control seeks error-insensitive control pulses t…
Excited-CAFQA: A classical simulation bootstrap for the variational estimation of molecular excited states
Bikrant Bhattacharyya, Gokul Ravi
Variational Quantum Algorithms (VQAs) are iterative algorithms suited to implementation on current-era quantum devices. VQAs employ classical optimization to minimize cost function…
Using optimal control to guide neural-network interpolation of continuously-parameterized gates
Bikrant Bhattacharyya, Fredy An, Dominik Kozbiel +2
Control synthesis for continuously-parameterized families of quantum gates can enable critical advantages for mid-sized quantum computing applications in advance of fault-tolerance…
Optimal Clifford Initial States for Ising Hamiltonians
Bikrant Bhattacharyya, Gokul Subramanian Ravi
Evaluating quantum circuits is currently very noisy. Therefore, developing classical bootstraps that help minimize the number of times quantum circuits have to be executed on noisy…
