science π‘ Sunlight now makes quantum entanglement
Researchers successfully demonstrated that sunlight can generate quantum entanglement between photons. This breakthrough occurred involving Robert Boyd's group at the University of Ottawa and Hanieh Fattahi's team at the Max Planck Institute for the Science of Light in Germany. The findings were published in Optica, detailing results from an outdoor experiment. This paves the way for more energy-efficient quantum technologies, potentially enabling space-based secure encryption. The team is now focused on scaling this proof-of-principle experiment outside the lab. π‘
