A team led by ORNL scientists developed a new method to estimate continuous-variable quantum states. This method uses Bayesian inference in a complete quantum state tomography workflow capable of inferring generic continuous-variable states measured by homodyne or heterodyne detection with no assumption of Gaussianity. The approach was demonstrated experimentally with a wide variety of continuous-variable states.
