Originally devised as an extension of von Neumann measurement Hamiltonian to joint measurement of conjugate variables, the Arthurs-Kelly Hamiltonian has been found to have many other practical applications. I summarize in particular, experimental bounds on von Neumann entropy, noiseless quantum tracking of conjugate observables, remote tomography, entanlement swapping and exact measurement of correlation between conjugate observables.

I summarize in particular, experimental bounds on von Neumann entropy, noiseless quantum tracking of conjugate observables, remote tomography, entanlement swapping and exact measurement of correlation between conjugate observables.
