Errors in quantum tomography: diagnosing systematic versus statistical errors
Nathan K. Langford
A prime goal of quantum tomography is to provide quantitatively rigorous characterisation of quantum systems, be they states, processes or measurements, particularly for the purpos…
Boson Sampling on a Photonic Chip
Justin B. Spring, Benjamin J. Metcalf, Peter C. Humphreys +11
While universal quantum computers ideally solve problems such as factoring integers exponentially more efficiently than classical machines, the formidable challenges in building su…
Multi-photon quantum interference in a multi-port integrated photonic device
Benjamin J. Metcalf, Nicholas Thomas-Peter, Justin B. Spring +11
Increasing the complexity of quantum photonic devices is essential for many optical information processing applications to reach a regime beyond what can be classically simulated,…
Enhancing multiphoton rates with quantum memories
J. Nunn, N. K. Langford, W. S. Kolthammer +6
Single photons are a vital resource for optical quantum information processing. Efficient and deterministic single photon sources do not yet exist, however. To date, experimental d…
