An Entanglement Filter
Ryo Okamoto, Jeremy L. O'Brien, Holger F. Hofmann +3
The ability to filter quantum states is a key capability in quantum information science and technology, in which one-qubit filters, or polarizers, have found wide application. Filt…
Beating the standard quantum limit: Phase super-sensitivity of N-photon interferometers
Ryo Okamoto, Holger F. Hofmann, Tomohisa Nagata +3
Quantum metrology promises greater sensitivity for optical phase measurements than could ever be achieved classically. Here we present a theory of the phase sensitivity for the gen…
Beating the Standard Quantum Limit with Four Entangled Photons
Tomohisa Nagata, Ryo Okamoto, Jeremy L. O'Brien +2
Precision measurements are important across all fields of science. In particular, optical phase measurements can be used to measure distance, position, displacement, acceleration a…
