Quantum pendulum clock overcomes classical accuracy limits and sheds light on quantum to classical transitions

In a grandfather clock, a pendulum swings back and forth and this periodic motion is maintained using the energy stored in its suspended weights. This is done with the help of the escapement mechanism ...

First quantum grandfather clock could probe where gravity comes from

The first complete design for a quantum grandfather clock uses a single atom, tiny mirrors and light. Building it could help our understanding of what makes any clock accurate in the quantum realm and ...
