The experiment used error-corrected logical qubits to run a complex quantum circuit that classical simulation methods could not practically reproduce. “Verification remains one of the biggest challenges in firmly establishing experimental quantum advantage,” said Bill Fefferman, associate professor at the University of Chicago. “We are now firmly in the quantum advantage era,” said Jay Gambetta, director of IBM Research and IBM Fellow. “Beyond strengthening experimental validation, advances in verification have the potential to unlock practical applications for the next generation of quantum computers.” The researchers have released the circuits and results through IBM’s Quantum Advantage Tracker, allowing the work to be examined alongside other quantum advantage demonstrations.
