Quantum metrology in the joint measurement of multiple non-commuting observables with SU(1,1) interferometer

We simultaneously measure the multiple non-commuting observables carried by an optical field with the SU(1,1) nonlinear interferometer, and demonstrate that joint measurement of three non-commuting observables have a sensitivity beating the standard quantum limit.
