Are you certain, Mr. Heisenberg? New measurements deepen understanding of quantum uncertainty
Heisenberg's Uncertainty principle is arguably one of the most famous foundations of quantum physics. It says that not all properties of a quantum particle can be measured with unlimited accuracy. Until now, this has often ...

Scientists set a new record for measuring magnetic vibrations using the spin of a single atom
The lab, though it may seem quiet and insulated, can be as full of background noise as a crowded train station when we're trying to catch the announcements. Our brains can filter out the noise and focus on the message up ...
