Researchers from Stockholm University, the Nordic Institute for Theoretical Physics, and Ca’ Foscari University of Venice have shown that laser light can induce quantum behavior at room temperature, simplifying quantum technology experiments.

In parallel, Chinese scientists have developed a quantum light source based on gallium nitride (GaN), a material typically used in blue LEDs, which broadens the wavelength range available for quantum computing applications.

The GaN-based quantum light source is a step towards compact and durable quantum chips that could transform the construction of quantum circuits.

An international team led by the University of Vienna demonstrated quantum interference with multiple single photons, advancing optical quantum computing through a resource-efficient approach.

These breakthroughs collectively signify substantial progress in photonic quantum chip technology and could lead to quantum technologies being used outside of specialized labs.
