Quantum mechanics shows that particles in our universe do not have fixed properties like everyday objects. They exist in a state of superposition until a disturbance forces them to "choose" a reality.

A cornerstone of quantum physics is uncertainty. Heisenberg’s uncertainty principle states the more precisely you pinpoint the position of a particle, the less precisely you can know its momentum at ...

By using something called a quantum grid, scientists have found a clever way to simultaneously measure momentum and position ...
