- Abstract
Squeezed vacuum is a versatile resource of bipartite entanglement for quantum metrology and information. Optical parametric oscillators generate these states in a frequency comb structure. We show the simultaneous detection of 18 teeth with 11 dB of squeezing each. We built a 1.5-m-long optical resonator to increase the spectral teeth density and significantly increase the detection bandwidth by employing unbalanced homodyne detection instead of balanced. Our approach can be a crucial step in using the scaling potential of high-frequency squeezed states in quantum information.
