Experimental Generation of Broadband Quadrature Entanglement Using Laser Pulses
Yun Zhang, Ryuhi Okubo, Tatsuya Furuta, Takuya Hirano · International Conference on Quantum Information · 2007
We report the generation of broadband pulsed quadrature entanglement by combing two squeezed vacua with squeezing of 3.4±0.2 dB and bandwidth of 200 MHz, which are generated from two degenerate optical parametric amplifiers.
