D-Wave (NYSE: QBTS), a leader in quantum computing systems, software and services, has published a peer-reviewed milestone study of the first large-scale demonstration of coherent quantum annealing. For the first time, the research exhibits dynamics of a quantum phase transition in a large-scale programmable quantum annealing processor using up to 2000 qubits in a D-Wave processor.
The announcement reads, “The paper—a collaboration between scientists from D-Wave, the University of Southern California, the Tokyo Institute of Technology, and Saitama Medical University—entitled ‘Coherent quantum annealing in a programmable 2000-qubit Ising chain,’ was published in the peer-reviewed journal Nature Physics today and is available here. The study shows that the fully programmable D-Wave quantum processor can be used as an accurate simulator of coherent quantum dynamics at large scales. This was demonstrated showing the patterns of ‘kinks’ separating correlated spins in almost perfect agreement with exact analytical solutions of the famous Schrodinger equation for an ideal quantum system, completely isolated from outside noise. The density and spacing of kinks depend on, among other things, the speed and ‘quantumness’ of the experiment. Measurements of single-qubit parameters were shown to accurately predict the behavior of systems from 8 to 2000 qubits, demonstrating high levels of control in quantum simulations at all scales.”
“Coherence is the holy grail of quantum computing. By simulating a closed quantum system with no thermal effects at a large scale, we can glean invaluable insights into our processors’ computational power and thus increase the ability to find high quality solutions for our customers,” said Alan Baratz, CEO of D-Wave. “Ongoing advances in coherence times are an important priority for both our annealing and gate-model programs. The demonstration of large-scale coherence is another step towards demonstrating practical quantum advantage, and today’s research is a significant step towards that milestone.”
