Quantum Annealing Breakthrough: D-Wave'S 5,000 Qubit Processor Shows Faster Coherent Dynamics Than Classical Computing.

D-Wave Quantum Inc. has achieved another major breakthrough in quantum computing. In a peer-reviewed study published on April 19, 2023, the company reported the largest programmable quantum simulation to date. The computation utilized over 5,000 qubits in the D-Wave Advantage quantum computer, showcasing the first-ever evidence of coherent quantum dynamics being faster than classical dynamics in a programmable 3D spin glass, a notoriously difficult optimization problem to solve.

This milestone achievement is a significant step forward for quantum computing and demonstrates the potential for quantum technologies to revolutionize industries such as finance, healthcare, and transportation. The study showcases D-Wave’s unique approach to building both annealing and gate-model quantum computers, positioning the company as a leader in the rapidly evolving quantum computing industry.

The article entitled “Quantum critical dynamics in a 5,000-qubit programmable spin glass” was published in the esteemed, peer-reviewed journal Nature, representing a collaboration between D-Wave and Boston University scientists.

D-Wave’s Quantum Processor Demonstrates Coherent Quantum Dynamics in Large-Scale Optimization Problems Using Commercial-Grade Annealing-Based Quantum Computer

The study builds upon prior research conducted on up to 2,000 qubits in September of last year, demonstrating that D-Wave’s quantum processor can accurately compute coherent quantum dynamics in large-scale optimization problems. Notably, the study was conducted using D-Wave’s commercial-grade annealing-based quantum computer, which is presently accessible for utilization by customers.

Although various models of quantum computers are presently under development, this outcome highlights the unique capabilities of D-Wave’s annealing-based quantum computing system in efficiently solving complex optimization problems.

“This research marks a significant achievement for quantum technology, as it demonstrates a
computational advantage over classical approaches for an intractable class of optimization problems. For those seeking evidence of quantum annealing’s unrivaled
performance, this work offers definitive proof.”

Dr. Alan Baratz, CEO of D-Wave.

The research has immediate implications for optimization as it indicates that quantum annealing can enhance solution quality more quickly than classical annealing-based algorithms by passing through quantum phase transition instead of the corresponding thermal phase transition. The low-energy states generated by quantum annealing correspond to low-cost solutions for optimization problems, and the observed speedup is consistent with the theory of coherent quantum annealing, thereby supporting the use of large-scale quantum computation and the scaling advantage in energy optimization.

Moreover, the study establishes a direct correlation between coherence and the core computational power of quantum annealing, thus validating D-Wave’s efforts to improve coherence to achieve better performance on real-world optimization problems.

The study reinforces D-Wave’s unwavering commitment to scientific progress and providing advanced products, as the organization works on developing future annealing and gate model quantum computers.

“This is an important advance in the study of quantum phase transitions on quantum annealers. It
heralds a revolution in experimental many-body physics and bodes well for practical applications of
quantum computing.The same hardware that has already provided useful experimental

“Disordered magnets, such as spin glasses, have long functioned as model systems for testing solvers of complex optimization problems. This paper gives evidence that the quantum
dynamics of a dedicated hardware platform are faster than for known classical algorithms to find the
preferred, lowest energy state of a spin glass, and so promises to continue to fuel the further
development of quantum annealers for dealing with practical problems.”

“As a physicist who has built my career on computer simulations of quantum systems, it has been
amazing to experience first-hand the transformative capabilities of quantum annealing devices. This paper already demonstrates complex quantum dynamics on a scale beyond any classical simulation method, and I’m very excited about the expected enhanced performance of future devices. I believe we are now entering an era when quantum annealing becomes an essential tool for research on complex systems.”

“This represents some of the most important experimental work ever performed in quantum
optimization. We’ve demonstrated a speedup over simulated annealing, in strong agreement with theory, providing high-quality solutions for large-scale problems. This work shows clear evidence of quantum dynamics in optimization, which we believe paves the way for even more complex problem solving using quantum annealing in the future. The work exhibits a programmable realization of lab experiments that originally motivated quantum annealing 25 years ago.”

Dr. Andrew King, Director of Performance Research at D-Wave.

“Not only is this the largest demonstration of quantum simulation to date, but it also provides the first experimental evidence, backed by theory, that coherent quantum dynamics can accelerate the
attainment of better solutions in quantum annealing.

The observed speedup can be attributed to complex critical dynamics during quantum phase transition, which cannot be replicated by classical annealing algorithms, and the agreement between theory and experiment is remarkable. We believe these findings have significant implications for quantum optimization, with practical applications in addressing real-world problems.”

Over the years, D-Wave has unveiled five generations of quantum computers, and it launched a preliminary model of its sixth-generation device, the Advantage2 system, in June 2022. The completed Advantage2 system will have more than 7,000 qubits, 20-way connectivity, and enhanced coherence to tackle even more significant and complex problems.
