Quantum researchers have succeeded in dividing one photons into three, Researchers at Waterloo University’s in Institute for Quantum Computing (IQC) reported the first appearance of the direct breakdown of one photon into three.

Advent, the first of its kind, uses the spontaneous parametric downconversion (SPDC) method in quantum optics and has created what quantum optical researchers call a non-Gaussian state of light.

The state of non-Gaussian light is seen as an important component for achieving quantum excellence.

“It has been recognized that the type of attachment created by the two-photon version has limits, but these results form the core of an exciting new paradigm for three-photon quantum optics,” said Chris Wilson, principal investigator in the IQC faculty member and professor of electrical and computer technology in Waterloo. Quantum researchers have succeeded in dividing one photons into three.

Given that this research goes beyond our ability to divide photons into two weaving photons, we are optimistic that we have found a new field of research.

“The two-tone version has been a workhorse for quantum research for more than 30 years,” Wilson said. We believe that three photons will cross the line and promote further theoretical research and experimental applications, and we hope that optical quantum calculations with superconducting units will be developed. Quantum researchers have succeeded in dividing one photons into three.

Wilson uses microwave photons to expand the known limits of SPDC. Experimental implementation using superconducting parametric resonators.

The results clearly show a strong dependency between the three photons produced at different frequencies. Current work must show that photons are involved.

“Non-Gaussian status and operations are the main elements in achieving quantum excellence,” Wilson said.

They are very difficult to simulate and model classically, which leads to a lack of theoretical work for this application.
