"WebIn a conventional atomic interferometer employing N atoms, the phase sensitivity is at the standard quantum limit: 1/N. Under usual spin squeezing, the sensitivity is increased by lowering the quantum noise. It is also possible to increase the sensitivity by leaving the quantum noise unchanged while producing phase amplification. Here we show how to … " - How laser interferometer work
