The Blurry Line between Small and Quantum Small

The late physicist Erwin Schrodinger was probably relieved to know that flesh and blood cats are too big to behave according to the laws of quantum physics. His intellectual heirs, however, no longer have that luxury. The line between the large and the small is not so clear cut as it was in Schrodinger’s day. [...]

Transistor Shrunk Down to Scale of Single Phosphorus Atom

The shift from fragile, bulky vacuum tubes to solid-state transistors paved the way for the information age. And the steady downsizing of transistors has made the devices of the information age ubiquitous, thanks to processors that become smaller, cheaper and faster with each passing year. Now a group of physicists has demonstrated how far that [...]

Physicists entangle a record-breaking 14 quantum bits

14 entangled calcium-ion qubits

Quantum information science is a bit like classroom management—the larger the group, the harder it is to keep everything together. But to build a practical quantum computer physicists will need many particles working in synchrony as quantum bits, or quibits. Each qubit can be a 0 and a 1 simultaneously, vaulting the number-crunching power of [...]
