Quantum Compiling

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a quantum computing system and method that significantly reduces computational delays in hybrid quantum algorithms. It does so by having the classical processor (CPU) speculatively compile multiple sets of quantum gate instructions based on predictions of possible measurement results from the quantum processor (QPU). When the actual measurement result becomes available, the system quickly selects the pre-compiled set of quantum instructions that matches the outcome, minimizing waiting time and improving overall quantum computation efficiency.
