A quantum register (also known as a qregister) is the quantum mechanical analogue of a classical processor register.
A mathematical description of a quantum register is achieved by using a tensor product of qubit bra or ket vectors. For example, an n qubit quantum register is described by an element in the tensor product Hilbert space
Famous quotes containing the words quantum and/or register:
“A personality is an indefinite quantum of traits which is subject to constant flux, change, and growth from the birth of the individual in the world to his death. A character, on the other hand, is a fixed and definite quantum of traits which, though it may be interpreted with slight differences from age to age and actor to actor, is nevertheless in its essentials forever fixed.”
—Hubert C. Heffner (1901–1985)
“Our fear that Communism might some day take over most of the world blinds us to the fact that anti-communism already has.”
—Anonymous U.S. Analyst In 1967. Quoted in “The Uses of Anticommunism,” vol. 21, published in The Socialist Register (1985)
