Banchi L, Kolthammer W, Kim M
Phys Rev Lett . 2019 Jan; 121(25):250402. PMID: 30608836
Determining an unknown quantum state from an ensemble of identical systems is a fundamental, yet experimentally demanding, task in quantum science. Here we study the number of measurement bases needed...

Posner M, Hiemstra T, Mennea P, Bannerman R, Hoff U, Eckstein A, et al.
Opt Express . 2018 Nov; 26(19):24678-24686. PMID: 30469580
Direct UV-written waveguides are fabricated in silica-on-silicon with birefringence of (4.9 ± 0.2) × 10, much greater than previously reported in this platform. We show that these waveguides are suitable...

Menssen A, Jones A, Metcalf B, Tichy M, Barz S, Kolthammer W, et al.
Phys Rev Lett . 2017 Apr; 118(15):153603. PMID: 28452506
Quantum interference of two independent particles in pure quantum states is fully described by the particles' distinguishability: the closer the particles are to being identical, the higher the degree of...

Kaczmarek K, Saunders D, Sprague M, Kolthammer W, Feizpour A, Ledingham P, et al.
Opt Lett . 2015 Dec; 40(23):5582-5. PMID: 26625056
Alkali-filled hollow-core fibers are a promising medium for investigating light-matter interactions, especially at the single-photon level, due to the tight confinement of light and high optical depths achievable by light-induced...

Humphreys P, Metcalf B, Spring J, Moore M, Salter P, Booth M, et al.
Opt Express . 2014 Oct; 22(18):21719-26. PMID: 25321548
We present a practical method for active phase control on a photonic chip that has immediate applications in quantum photonics. Our approach uses strain-optic modification of the refractive index of...

Humphreys P, Kolthammer W, Nunn J, Barbieri M, Datta A, Walmsley I
Phys Rev Lett . 2014 Oct; 113(13):130502. PMID: 25302876
We develop a scheme for time-frequency encoded continuous-variable cluster-state quantum computing using quantum memories. In particular, we propose a method to produce, manipulate, and measure two-dimensional cluster states in a...

Vidrighin M, Donati G, Genoni M, Jin X, Kolthammer W, Kim M, et al.
Nat Commun . 2014 Apr; 5:3532. PMID: 24727938
Phase estimation, at the heart of many quantum metrology and communication schemes, can be strongly affected by noise, whose amplitude may not be known, or might be subject to drift....

Humphreys P, Metcalf B, Spring J, Moore M, Jin X, Barbieri M, et al.
Phys Rev Lett . 2013 Oct; 111(15):150501. PMID: 24160584
We present a scheme for linear optical quantum computing using time-bin-encoded qubits in a single spatial mode. We show methods for single-qubit operations and heralded controlled-phase (cphase) gates, providing a...

Calkins B, Mennea P, Lita A, Metcalf B, Kolthammer W, Lamas-Linares A, et al.
Opt Express . 2013 Oct; 21(19):22657-70. PMID: 24104153
The integrated optical circuit is a promising architecture for the realization of complex quantum optical states and information networks. One element that is required for many of these applications is...

Spring J, Salter P, Metcalf B, Humphreys P, Moore M, Thomas-Peter N, et al.
Opt Express . 2013 Jun; 21(11):13522-32. PMID: 23736605
A key obstacle to the experimental realization of many photonic quantum-enhanced technologies is the lack of low-loss sources of single photons in pure quantum states. We demonstrate a promising solution:...
