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.”
—Hubert C. Heffner (1901–1985)
“I am more and more convinced that, with reference to any public question, it is more important to know what the country thinks of it than what the city thinks. The city does not think much.”
—Henry David Thoreau (1817–1862)
“With its frame of shaking curls all in disarray,
earrings swinging,
make-up smudged by beads of sweat,
eyes languid at the end of lovemaking,
may the face of the slim girl
who’s riding on top of you
protect you long.
What’s the use
of Vi.s».n»u, iva, Skanda,
and all those other gods?”
—Amaru (c. seventh century A.D.)
