Phase Reversal

Henry is in peril after bailing out from a burning airplane, because his quantum suit has uncontrollably split him into four quantum versions, only one of which can get hold of the parachute. In order to survive, all his versions must recombine via interference exactly where the parachute is. To this end, the phases of all his versions must be fully in control. Alas, Henry’s ejection has scrambled (randomized) his phases by decoherence (dephasing), which is common in quantum systems. A tip from Eve in mid-air concerning phase reversal proves to be a life saver! This decoherence control, which is indispensable in MRI, is termed sin echo, as the dynamics after the phase reversal echoes the dynamics before this operation. The much further-reaching potential goal of decoherence control may be to influence metabolism and even the process of dying. The appendix to this chapter explains dephasing and its control by the spin-echo method.
