The U.S. National Science Foundation’s Physics Frontiers Centers program renewed a grant to the MIT-Harvard Center for Ultracold Atoms (CUA) to fund exploring, understanding, and harnessing mysterious phenomena at the frontiers of physics. The CUA, which works to enable greater control and programmability of quantum-entangled systems of low-temperature atoms and molecules, will conduct experiments involving...

In its most famous form, the Heisenberg uncertainty relation tells us that we cannot know both the position and momentum of a particle. The best we can do is to redistribute the intrinsic quantum uncertainty, for example by making position more precise at the expense of momentum, via a procedure known as squeezing. However, the...
