THE UNCERTAINTY PRINCIPLE – TIME AND ENERGY In the last chapter we saw that if all particles had a particle-wave nature obeying the de Broglie relationship p = h/λ , then there would be a fundamental restriction to the accuracy with which one could make experimental measurements. This limit is known ...

Highly efficient optical quantum memory with long coherence time in
... The GEM scheme [12,17] uses an atomic medium that is inhomogeneously broadened by a magnetic field gradient. Light is absorbed into the atomic ensemble to create an atomic coherence, which then dephases due to the applied broadening gradient. The reversal of the gradient gives rise to the rephasing ...
