Ramsey experiment

WebbWe commonly call this a Ramsey experiment. Experiment two : Prepare the qubit in a superposition state and apply half the wait time and then apply a pi-pulse (X operator) and then the remainder of the wait time and measure in the superposition basis. Ramsey interferometry, also known as the separated oscillating fields method, is a form of particle interferometry that uses the phenomenon of magnetic resonance to measure transition frequencies of particles. It was developed in 1949 by Norman Ramsey, who built upon the ideas of his mentor, Isidor Isaac Rabi, … Visa mer The Rabi method A simplified version of the Rabi method consists of a beam of atoms, all having the same speed $${\displaystyle v}$$ and the same direction, sent through one interaction zone of … Visa mer Early interpretations of atom interferometers, including those of Ramsey, used a classical description of the motion of the atoms, but Bordé introduced an interpretation that used a quantum description of the motion of the atoms. Strictly … Visa mer Atomic clocks and the SI definition of the second An atomic clock is fundamentally an oscillator whose frequency $${\displaystyle \omega }$$ is matched to that of an atomic transition of a two-level atom, Visa mer
