y to remain in a cell for a much longer time, Ye said.
“What this means is, we can make sure there is only one atom per cell in our atomic clock,” Ye said. “Understanding of these processes will allow us to figure out a better path for making improved clocks, as particles inevitably will interact if we pack enough of them nearby to improve signal strength.”
The JILA team also found that packing three or more atoms into a cell could result in long-lived, highly entangled states, meaning the atoms’ quantum properties were linked in a stable way. This simple method of entangling multiple atoms may be a useful resource for quantum information processing.
