In Brief

• Researchers have created quantum dot light-emitting diodes (LEDs) that can produce entangled photons, which could be used to encode information in quantum computing.
• As of June, the record for the most photons entangled at a time was 10. Before that, the record was eight and that could only be produced at a rate of around nine events per hour.

Researchers from the Tyndall National Institute have devised a method that would make entangling photons easier, and accelerate our journey towards the quantum computing age.

“We have engineered a scalable array of electrically driven quantum dots using easily-sourced materials and conventional semiconductor fabrication technologies, and our method allows you to direct the position of these sources of entangled photons,” says researcher Emanuele Pelucchi.
