A team of JILA researchers has for the first time succeeded in combining two of the most “frightening” features of quantum mechanics to create a better quantum sensor: the entanglement between atoms and the delocalization of atoms. JILA is a physical science research institute operated by the National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder.
For the first time, scientists have succeeded in combining two of the most “frightening” features of quantum mechanics to create a better quantum sensor: the entanglement between atoms and the delocalization of atoms. The achievement was accomplished by the team of JILA researchers and NIST Fellow James K. Thompson.
Einstein originally referred to entanglement as creating frightening action at a distance – the strange effect of quantum mechanics where what happens to one
” data-gt-translate-attributes=”[{” attribute=””>atom somehow influences another atom located somewhere else. Entanglement is at the heart of the envisioned quantum computers, quantum simulators, and quantum sensors of the future. A second rather spooky aspect of quantum mechanics is delocalization, the fact that a single atom can be in more than one place at the same time.
“By learning to harness and control all of the spookiness we already know about, maybe we can discover new spooky things about the universe that we haven’t even thought of yet!” — James K. Thompson
As described in their paper that was published in the journal Nature on October 19, the Thompson group has combined the spookiness of both entanglement and delocalization to realize a matter-wave interferometer that can sense accelerations with a precision that surpasses the standard quantum limit (a limit on the
