Expands addressable problem class and
unlocks more real-world use cases for enterprises
D-Wave Quantum Inc. – a global leader in quantum computing
software, services, and systems, and the only quantum computing
company building both annealing and gate model quantum computers –
today announced two key updates to its constrained quadratic model
(CQM) hybrid solver in the Leap™ quantum cloud service. The CQM
hybrid solver can address real-world commercial-scale optimization
problems of up to one million variables (including continuous
variables) and 100,000 constraints. With today’s updates,
businesses now can further leverage the power of quantum
computation to run quadratic optimization problems with weighted
constraints and benefit from presolve techniques that streamline
and simplify problem formulation.

The updated constrained quadratic model
(CQM) hybrid solver from D-Wave enables quantum developers to more
accurately model problems where it is not possible to satisfy all
constraints. It expands the addressable use cases across various
industries, e.g. logistics (employee scheduling), manufacturing
(bin packing), and financial services (portfolio optimization).

The updated CQM solver allows quantum developers to better
represent commercial problems, enabling them to more easily and
accurately model problems where it is not possible to satisfy all
constraints through classical computing logic. For example, in an
employee scheduling scenario where employees should work 8 hours
per shift with optional overtime, the solver is now able to allow
for a soft “weighted” constraint of <8 hours and a hard
constraint of <12 hours, thereby increasing the utility of the
proposed solution. Support for weighted constraints enables
developers to unlock new use cases as well as expand the
applicability of existing use cases across various industries, e.g.
energy (electrical grid optimization), logistics (scheduling),
shipping (bin packing), and financial services (portfolio
optimization), while improving time-to-solution and easing problem
formulation.
In addition to supporting weighted constraints, the updated CQM
solver introduces a new set of fast classical algorithms that
reduces the size of the problem and allows for larger models to be
submitted to the hybrid solver. Presolve techniques remove
unnecessary variables and constraints to achieve a cleaner dataset,
resulting in better quality solutions by narrowing the problem
set/size and streamlining problem formulation. These techniques
are now automatically applied to all CQM problems in the CQM solver
in Leap and are also available in the Ocean SDK.
“As more companies turn to quantum computing today to solve
their increasingly complex business challenges, they’re seeking
ways to quickly and efficiently codify problems in order to
expedite time-to-solution,” said Murray Thom, vice president of
product management at D-Wave. “These enhancements to our CQM
solver, which were driven in large part by our customers’ feedback,
are designed to accelerate the quantum-hybrid workflow and help
companies more quickly derive business value from quantum
computing.”
D-Wave continues to innovate on the CQM solver, first introduced
in October 2021, to meet customer and market commercial application
needs. The CQM solver enables users to benefit from a simplified
expression of their constrained problems by directly incorporating
problem constraints. With the CQM solver, customers can address
larger and more complex real-world business problems. In addition
to today’s update, D-Wave added support of continuous variables to
the CQM solver in May 2022.
To learn more about the updates to our CQM quantum hybrid
solver, we invite you to attend the demo webinar on November 17 and
review the benchmarking report, which was published today.
