Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo report the first occurrence of directly splitting one photon into three.
The occurrence, the first of its kind, used the spontaneous parametric down-conversion method (SPDC) in quantum optics and created what quantum optics researchers call a non-Gaussian state of light. A non-Gaussian state of light is considered a critical ingredient to gain a quantum advantage.
Researchers at the Institute for Quantum Computing (IQC) have demonstrated a new method, called cycle benchmarking, to assess scalability and compare capabilities of different quantum computer platforms.
The finding leads the way towards establishing standards for quantum computing performance and strengthens the global effort to build a large-scale, practical quantum computer.
