A proposed method of profoundly enhancing the energy efficiency of wireless networks unfortunately also suffers from being amongst computationally complex problems to solve. But a computer scientist has for the first time demonstrated that the quantum search algorithm can solve this problem faster than a classical computer.

A novel wireless communications technique that turns the on-off status of parts of the telecommunications medium itself—such as antennas and subcarriers—could deliver super-charged energy efficiency gains, but its optimization suffers from being a problem that counts among computationally hard class of problems to solve. However, a Yokohama National University scientist has for the first time demonstrated that the quantum search algorithm can solve this problem faster than a classical computer in terms of query complexity.

The paper describing his findings appeared in the journal IEEE Access on August 9.
