This talk will illustrate the benefits offered by QIP with two devices which use quantum entanglement among nuclear spins to defeat the Heisenberg limits: (1) a spin gyroscope that operates by detecting the frequency shift in the spins’ precession rate in the rotating frame, which is potentially more accurate than mechanical or optical devices; (2) a quantum amplifier which correlates the states of a macroscopic number of nuclear spins with the state of a single target spin, so that a collective measurement of the state of the amplifier’s spins reveals that of the target spin.
