D-Wave a leading quantum computing company, has announced successful Quantum Error Mitigation (QEM) in its Advantage2 annealing quantum computing prototype. The QEM techniques reduce errors in quantum simulations, leading to results consistent with the quantum system maintaining its quantum state for a significantly longer time. This advancement is expected to improve performance in the forthcoming Advantage2 system and future processors. The research, led by Mohammad Amin, marks D-Wave’s first experimental demonstration of Zero-Noise Extrapolation, a practical QEM technique. This could help tackle complex problems in scientific and machine learning applications.
Quantum Computing Advancements: Error Mitigation Techniques
The techniques used reduce errors in quantum simulations, producing results consistent with the quantum system maintaining its quantum state, known as “coherence”, for a significantly longer time than an unmitigated system. These techniques are expected to enhance performance in the forthcoming Advantage2 system and future processors.
Quantum computation can be hindered by environmental noise and hardware imperfections, known as “errors“. While Quantum Error Correction is widely acknowledged 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), a practical QEM technique, within its annealing quantum computing systems.
Quantum Computing: Overcoming Obstacles
“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. The successful mitigation of such errors in quantum annealing produces 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.
Quantum Computing: Coherent Annealing Advancements
This work is the latest in the company’s advancements of coherent annealing quantum computing. In September 2023, D-Wave announced progress in the development of high coherence fluxonium qubits. D-Wave has designed, manufactured, and operated fluxonium qubits that have demonstrated quantum properties comparable to the best in peer-reviewed scientific literature.

D-Wave’s mission is to unlock the power of quantum computing today to benefit business and society. They aim to deliver customer value with practical quantum applications for problems as diverse as logistics, artificial intelligence, materials sciences, drug discovery, scheduling, cybersecurity, fault detection, and financial modelling. D-Wave’s technology has been used by some of the world’s most advanced organisations including Volkswagen, Mastercard, Deloitte, Davidson Technologies, ArcelorMittal, Siemens Healthineers, Unisys, NEC Corporation, Pattison Food Group Ltd., DENSO, Lockheed Martin, Forschungszentrum Jülich, University of Southern California, and Los Alamos National Laboratory.
Quantum Computing: Future Prospects
The techniques for QEM are expected to have a significant impact on D-Wave’s forthcoming Advantage2 system and future processors, and the potential benefits to customers stemming from these research results are promising. However, these forward-looking statements are subject to a number of risks and uncertainties, including the continued success of the techniques used in the research, general economic conditions and other risks, the ability to expand the customer base and the customer adoption of the solutions, and unanticipated technological or project development challenges.
