摘要：
Spatial quantum optics based on the high-order transverse mode is important for the super-resolution measurement and quantum image beyond the shot noise level. Quantum entanglement of the transverse plane Hermite–Gauss TEMmode has been demonstrated experimentally in this paper. Two squeezed TEMmodes, which are generated by a pair of degenerate optical parametric amplifiers(DOPA) with the nonlinear crystals of periodically poled KTi OPO, have been combined to produce TEMmode entanglement using a beam splitter. The 1.5 dB for the sum of amplitude and 1.2 dB for the difference of phase below shot-noise level is achieved with the measurement system of a Bell state detection.
