Quantum Coupling in Action
Trapped ion quantum computers utilize the quantum coupling effect by suspending particles representing qubits in an array of ion traps. These particles are then induced into a state of quantum coupling by using optical pumping by a laser. Information can be stored in this state by coupling two or more qubits. While the individual particles may fluctuate their values, the quantum states of the two qubits remain locked in relation to each other, via Coulomb force. Any action by one of the coupled ions instantaneously alters the other to maintain the relative value. This allows the computer to hold information despite the instability of the individual particles.

Famous quotes containing the words quantum, coupling and/or action:
“The receipt to make a speaker, and an applauded one too, is short and easy.—Take of common sense quantum sufficit, add a little application to the rules and orders of the House, throw obvious thoughts in a new light, and make up the whole with a large quantity of purity, correctness, and elegancy of style.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“The time of the seasons and the constellations
The time of milking and the time of harvest
The time of the coupling of man and woman
And that of beasts. Feet rising and falling.
Eating and drinking. Dung and death.”
—T.S. (Thomas Stearns)
“Without our being especially conscious of the transition, the word “parent” has gradually come to be used as much as a verb as a noun. Whereas we formerly thought mainly about “being a parent,” we now find ourselves talking about learning how “to parent.” . . . It suggests that we may now be concentrating on action rather than status, on what we do rather than what or who we are.”
—Bettye M. Caldwell (20th century)
