University of Waterloo researchers have isolated one of three photons for the first time

For the first time, researchers at the University of Waterloo have isolated one of three photons. This phenomenon is described as the first occurrence and uses a method called spontaneous parameter conversion (SPDC). The experiment created what researchers call a state of non-gaussian light. Non-Gaussian light is considered to be a key factor in gaining quantum advantage. Scientists already know that the type of entanglement produced by the double photon version is limited. The results of this experiment lay the foundation for the quantum optics of three photons.

The scientists also point out that the new study allows the team to go beyond the known ability to split a photon into two entangled protons. The team believes they have opened up a new area of exploration. The researchers point out that the double photon version has been a major force in quantum research for the past three decades.

For the study, Wilson and his team used microwave photons to extend the known limits of SPDC. The experiment uses superconducting parameter resonators. The team said the results showed a strong correlation between the three photons produced at different frequencies. Researchers are continuing their efforts to prove that photons are entangled. Non-Gaussian states and operations are the key to obtaining quantum advantages. The team hopes that eventually their work will lead to the development of optical quantum computing using superconducting units. The team believes three photons will overcome current limits.
