The phase qubit is a superconducting device based on the superconductor-insulator-superconductor (SIS) Josephson junction, designed to operate as a quantum bit, or qubit. The phase qubit is closely related, yet distinct from, the flux qubit and the charge qubit, which are also quantum bits implemented by superconducting devices. A phase qubit coupled to a piezoelectric mechanical resonator was used to create the world's first quantum machine.

Famous quotes containing the word phase:
“I had let preadolescence creep up on me without paying much attention—and I seriously underestimated this insidious phase of child development. You hear about it, but you’re not a true believer until it jumps out at you in the shape of your own, until recently quite companionable child.”
—Susan Ferraro (20th century)
