Optimal Qubit Control Using Single-Flux Quantum Pulses
Per J. Liebermann, Frank K. Wilhelm · Physical Review Applied · 2016
As quantum processors become increasingly complex, their control infrastructure needs to move from lab to application scale. This study shows how superconducting single-flux-quantum logic can be applied in a way that meets the stringent precision requirements of quantum computing at high speed, using a strongly modified version of quantum optimal-control theory. These results bring us one step closer to a fast, high-fidelity, solid-state quantum computer.
