D-Wave Quantum (NYSE: QBTS), a leader in quantum computing systems, software, and services, is focused on delivering customer value via practical quantum applications for problems such as logistics, artificial intelligence, materials science, drug discovery, scheduling, fault detection, and financial modeling, and is the only provider building both annealing and gate-model quantum computers. Through its products, the company is unlocking commercial use cases in optimization today while building the technologies that enable new solutions for tomorrow.

Quantum annealing technology is a quantum computing method used to find the optimal solution to problems with many possible solutions by exploiting properties specific to quantum physics. Quantum annealing uses a cooling process, where the temperature is replaced by quantum energy, and the lowest energy state (global minimum), is found through the annealing process.

D-Wave has demonstrated coherent evolution through a quantum phase transition in the paradigmatic setting of a 1D transverse field Ising chain, using up to 2,000 superconducting flux qubits in a programmable quantum annealer. The experiments conducted by the company, and recently published in Nature Physics, demonstrate that large-scale quantum annealers can be operated coherently and can pave the way to exploiting coherent dynamics in quantum optimization, machine learning, and simulation tasks.

The company has concluded that by tuning the parameters of a programmable quantum annealer, it has simulated quantum critical phenomena in 1D chains of up to 2,000 spins. The results provide the foundation to support coherent quantum simulation on a previously unattainable scale. The experimental results give insight into coherence that is expected to support D-Wave’s development of annealing and gate-based quantum computers.

D-Wave’s annealing and gate-based computing represent two different approaches to applying quantum technology to provide solutions to the problems being processed. The company’s relentless pursuit of practical quantum computing has resulted in the technology being used today by some of the world’s most advanced enterprises – more than 25 of the Forbes Global 2000 trust D-Wave’s quantum computing technology to solve some of their largest computational problems.

D-Wave’s commercial customers include blue-chip industry leaders like Volkswagen, Accenture, BBVA, NEC Corporation, Save-On-Foods, DENSO, and Lockheed Martin. The company boasts an extensive IP portfolio featuring over 200 issued U.S. patents and over 100 peer-reviewed papers published in leading scientific journals.
