Quantum Reference Frame

A quantum reference frame is a reference frame which is treated quantum theoretically. It, like any reference frame, is a physical system which defines physical quantities, such as time, position, momentum, spin, and so on. Because it is treated within the formalism of quantum theory, it has some interesting properties which do not exist in a normal classical reference frame.

Famous quotes containing the words quantum, reference and/or frame:

    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.

    I can imagine no more comfortable frame of mind for the conduct of life than a humorous resignation.
