Some of the lab equipment needed to trap laser-cooled atoms Endres Lab
Extremely cold atoms have been connected into a state of quantum 鈥渉yperentanglement鈥 for the first time. This demonstrates a new level of control over their quantum properties, which could prove useful for quantum computing.
When cooled to temperatures very close to absolute zero 鈥 the lowest possible temperature 鈥 atoms don’t fully freeze in place, because quantum effects that don’t exist at warmer temperatures enable them to keep making tiny motions. A research team at the California Institute of Technology has now used laser light to take control of those motions in an unprecedented…
