A new study predicts a quantum Goldilocks effect
Coral Gables FL (SPX) Sep 25, 2015
Just as in the well-known children's story of Goldilocks and the Three Bears, something good happens when things are done in moderation, rather than in extremes. Now a new study has translated "not too hot or too cold, just right" to the quantum world and the generation of quantum entanglement - the binding within and between matter and light -and suggests that the universe started "neither too fast nor too slow." By studying a system that couples matter and light together, like the universe itsel ... read more
