Promising Results Expected to Drive Higher
Coherence for Forthcoming Advantage2 System and Future Processors,
Furthers Quantum Supremacy Efforts
D-Wave Quantum Inc. (NYSE: QBTS), a leader in quantum computing
systems, software, and services and the world’s first commercial
supplier of quantum computers, today announced important research
results that demonstrate successful Quantum Error Mitigation (QEM)
in its Advantage2 annealing quantum computing experimental
prototype. The techniques reduce errors in quantum simulations,
producing results consistent with the quantum system maintaining
its quantum state (“coherence”) for an order of magnitude longer
time than an unmitigated system. These techniques are expected to
drive performance advancements in the forthcoming Advantage2 system
and future processors.
Quantum computation can be hampered by environmental noise and
hardware imperfections, known as “errors.” While Quantum Error
Correction is widely acknowledged by the industry as the ultimate
solution for eliminating the impact of these errors, it comes with
significant overhead, making it impractical with the current state
of technology. QEM has emerged as a near-term solution for
estimating error-free expectation values in the presence of small
noise. This research marks D-Wave's first experimental
demonstration of Zero-Noise Extrapolation (ZNE), one of the most
practical QEM techniques, within its annealing quantum computing
systems. It offers valuable insights into the performance of more
coherent systems and assists in determining design specifications
for our next-generation processors. Further, these results could
prove beneficial for helping customers tackle highly
computationally complex problems in scientific-related and machine
learning applications.
“Errors represent the most significant obstacle in all forms of
quantum computation,” said Mohammad Amin, fellow, quantum
algorithms and systems, who led the research at D-Wave. “This work
demonstrates the successful mitigation of such errors in quantum
annealing, producing measurement results as if the qubits were
nearly one order of magnitude more coherent. This enables
computation in regimes that were previously inaccessible, such as
quantum simulations of exotic magnetic materials, an important
milestone on the road to demonstrating quantum supremacy on D-Wave
processors.”
This work is the latest in the company’s advancements of
coherent annealing quantum computing. In September 2023, D-Wave
announced notable progress in the development of high coherence
fluxonium qubits. D-Wave has designed, manufactured, and operated
fluxonium qubits that have demonstrated quantum properties that are
comparable to the best seen to date in peer-reviewed scientific
literature.
