Team controls two quantum light sources - Futurity: Research News

For years, researchers around the world have strived to develop stable quantum light sources and achieve the phenomenon known as quantum mechanical entanglement—a phenomenon, with nearly sci-fi-like properties, where two light sources can affect each other instantly and potentially across large geographic distances.

Researchers from the University of Copenhagen’s Niels Bohr Institute report the feat in the journal Science.

According to professor Peter Lodahl, it is a crucial step in the effort to take the development of quantum technology to the next level and to “quantize” computers, encryption, and the internet.

By doing so, we’ve revealed the key to scaling up the technology, which is crucial for the most ground-breaking of quantum hardware applications,” says Lodahl.

This is because a quantum bit can be both a 1 and 0 at the same time, which results in processing power that is unattainable using today’s computer technology.

According to Lodahl, just 100 photons emitted from a single quantum light source will contain more information than the world’s largest supercomputer can process.
