Quantum Manipulation Using Light-Atom Interaction
... The obtainable spin squeezing improves with the quality of the resonator and the number of atoms. Fig. 4 shows the calculated spin squeezing for a typical atom number (N=2×104) and varying finesse of the resonator. Note that we obtain excellent agreement between the calculation [23] and the experime ...

Total time derivatives of operators in elementary quantum mechanics
... which implies that the total derivative obeys the same algebraic rules as ordinary derivatives. Because this total time derivative is not defined to be a rate of change of anything, some may prefer to use a different symbol for it, for example, D t instead of d/dt, but the latter notation will be us ...

... As a more pertinent example, consider the mass of the Sun. The mass of a star determines its luminosity and -- using basic physics -- one can compute that life as we know it on Earth is possible only if the Sun's mass falls into the narrow range between 1.6x1030 and 2.4x1030 kilograms. Otherwise, Ea ...

With it, we have calculated the one-loop scattering amplitude among these four Goldstone bosons. Since the perturbative amplitude is polynomial in the ...

... there are two quite distinct ways for a quantum state to change. On the one hand there is unitary evolution, which is deterministic. If we specify the initial state |ψ(0)i, the theory predicts the state |ψ(t)i at a later time. But on the other hand there is measurement, which is probabilistic. The t ...

Quantum Teleportation
