A simple scheme for expanding photonic cluster states for quantum information
Pruet Kalasuwan, Gabriel Mendoza, Anthony Laing +6
We show how an entangled cluster state encoded in the polarization of single photons can be straightforwardly expanded by deterministically entangling additional qubits encoded in…
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…
