Complex Squeezing and Force Measurement Beyond the Standard Quantum Limit
L. F. Buchmann, S. Schreppler, J. Kohler +2
A continuous quantum field, such as a propagating beam of light, may be characterized by a squeezing spectrum that is inhomogeneous in frequency. We point out that homodyne detecto…
