Even with just one photon passing through per second, the calcite setup demonstrates how light ‘chooses’ a path, revealing the probabilistic essence of quantum mechanics. Using common ...

When Jian-Wei Pan looks up at the night sky, he pictures a ‘quantum satellite constellation’, a global network of communications satellites relaying light particles, or photons, that have been ...

he is convinced that the quantum computers of the future will be powered by light. “The ultimate goal is to develop quantum computers that are ultrafast and ultralarge scale,” says Furusawa.

Quantum light sources are fickle. They can flicker like stars in the night sky and can fade out like a dying flashlight. However, newly published research from the University of Oklahoma proves ...

In a collaboration between process engineering and photonics at TU Wien (Vienna), this problem has now been solved using a very special type of light source: terahertz radiation from a quantum ...

The University of Bristol has been at the forefront of showing that there are striking similarities between the Riemann zeros and the quantum energy levels of classically chaotic systems. From a ...

Later experiments demonstrated that light also behaves as particles, revealing its quantum nature. In this classic experiment ...

The company uses so-called "photonic" quantum computing, which has long been dismissed as impractical. The approach, which encodes data in individual particles of light, offers some compelling ...

The way the light wave is twisted also allows researchers to precisely control the material's quantum properties—rules that determine the behavior of electrons, which are essential for ...

The Palo Alto, California-based company's quantum computing technology manipulates particles of light, or photons, to perform the quantum calculations. The light-based approach has several ...
