Lasers are no longer required to produce quantum entanglement, physicists say, after achieving the state using sunlight.

Ronald Hanson is at QuTech and the Kavli Institute of Nanoscience, Delft University of Technology, Delft 2628 CJ, the Netherlands. The authors show that for a 10-km fibre link, entanglement between ...

A team of physicists from The City College of New York, along with Herriot-Watt University and Corning Incorporated, have demonstrated that the laser beams from ordinary laser pointers can mimic ...

Quantum signals are extremely fragile and can be overwhelmed by the intense optical noise generated by conventional internet traffic, requiring costly dedicated infrastructure for quantum networks.

Teleportation is a reality in 2025 — well, at least for quantum computers. In February 2025, Oxford University demonstrated the teleportation of quantum data from one independent quantum processor to ...
