Sunlight creates quantum entanglement once thought to require lasers
Scientists have turned ordinary sunlight into a source of quantum entanglement, opening a surprising path toward greener and more accessible quantum technology.

Summary:
Scientists have generated quantum entanglement directly from sunlight,
potentially offering a lower-energy alternative to the lasers normally used
in quantum technology.
Their outdoor experiment produced entangled photons with about 94% similarity
to an ideal state.
The result could pave the way for simpler quantum satellites, secure
communications, and more energy-efficient quantum computing.
