The combination of traditional and quantum computing gives way to discoveries.

Researchers have found a novel and more effective approach to link the reliability and efficiency of a quantum system with a classical computer.

This novel computer method opens the door to many algorithms and experiments that bring quantum scientists closer to short-term applications and technological discoveries.

"Future quantum computers may be used in a broad range of application including the removal of carbon dioxide from the atmosphere, artificial limbs, and the design of more efficient pharmaceuticals," says Christine Muschik, a senior researcher at the Institute of Computing Quants (IQC) and a faculty member of the University of Waterloo in physics and astronomy.

Hybrid computing, which combines a standard computer processor with a quantum coprocessor into a feedback band allows researchers a durable and adaptable strategy rather than just trying to employ a quantum computer.

As researchers are constructing hybrid, quantum-based computers, the research team at Muschik was interested in quantum calculations that could be carried out without gates.

They proposed a method in which a hybrid, classical quantum calculation is performed by a succession of measurements of an enclosed quantum condition.

For quantum software writers and experimenters, the theoretical study of the team is good news since it offers a fresh approach to thinking about algorithms for optimization.

The technique gives a high tolerance, frequently a problem in quantum systems, and works for numerous quantum states, including photonic quantum coprocessors.

In short-term quantum applications, hybrid computing represents a new boundary. Muschik and her colleagues hope that by eliminating the dependency on quantum gates, they will construct feedback loops that can be tuned to the datasets that the computers are researching more efficiently.

"Quantum computers are capable, although yet experimental and fragile, of addressing problems that supercomputers cannot," Mouschik told reporters.
