Adaptive protocols for SU(1,1) interferometers to achieve ab initio phase estimation at the Heisenberg limit

The precision of phase estimation with interferometers can be greatly enhanced using non-classical quantum states, and the SU(1,1) interferometer is an elegant scheme, which generates two-mode squeezed state internally and also amplifies the signal. It has been shown in Anderson et al (2017 Phys. Re...
