In trapped-ion machines, getting the right qubits together can mean giving the atoms a carefully controlled commute.
A missing atom can be useful hardware, and different diamond designs have very different ideas about staying cool.
Laser tweezers turn single atoms into movable quantum bits, and the resulting grid is something researchers can actually photograph.
The glamorous hardware in quantum-computer photos has a surprisingly practical job: keeping a tiny processor extraordinarily cold.
A 56-qubit machine and several supercomputers tackled a surprisingly tricky question: can you trust someone else’s digital coin toss?
Google’s qubits settled into an unusual repeating rhythm, giving researchers a new way to explore how matter behaves.
