Quantum-enhanced optical phase tracking: experiment and ultimate limits

Not Accessible

Your library or personal account may give you access


We surpass the coherent-state limit to optical phase tracking using a CW phase-squeezed beam. Our phase varies stochastically over a wide range and consequently the best precision is achieved for a finite degree of squeezing.
