Preparation contextuality powers parity-oblivious multiplexing
Robert W. Spekkens, D. H. Buzacott, A. J. Keehn +2
In a noncontextual hidden variable model of quantum theory, hidden variables determine the outcomes of every measurement in a manner that is independent of how the measurement is i…
Reply to "Comment on 'Measuring a Photonic Qubit without Destroying It'"
G. J. Pryde, J. L. O'Brien, A. G. White +2
In our Letter we proposed a scheme for nondeterministic quantum nondemolition (QND) measurement of the polarization of a single photon--a photonic qubit--using linear optics and ph…
Demonstrating quantum nonlocality without entanglement
G. J. Pryde, J. L. O'Brien, A. G. White +1
We experimentally demonstrate the superior discrimination of separated, unentangled two-qubit correlated states using nonlocal measurements, when compared with measurements based o…
High-Fidelity Z-Measurement Error Correction of Optical Qubits
J. L. O'Brien, G. J. Pryde, A. G. White +1
We demonstrate a quantum error correction scheme that protects against accidental measurement, using an encoding where the logical state of a single qubit is encoded into two physi…
Measuring a photonic qubit without destroying it
G. J. Pryde, J. L. O'Brien, A. G. White +2
Measuring the polarisation of a single photon typically results in its destruction. We propose, demonstrate, and completely characterise a \emph{quantum non-demolition} (QND) schem…
