    "abstract": "We propose a simple method for measuring the populations and the relative\nphase in a coherent superposition of two atomic states. The method is based on\ncoupling the two states to a third common (excited) state by means of two laser\npulses, and measuring the total fluorescence from the third state for several\nchoices of the excitation pulses.",
