Quantum-enhanced interferometry by entanglement-assisted rejection of environmental noise
Alex O. C. Davis, Giacomo Sorelli, Valerian Thiel +1
Sensing and measurement tasks in severely adverse conditions such as loss, noise and dephasing can be improved by illumination with quantum states of light. Previous results have s…
Conditional preparation of non-Gaussian quantum optical states by mesoscopic measurement
Alexander O. C. Davis, Mattia Walschaers, Valentina Parigi +1
Non-Gaussian states of an optical field are important as a proposed resource in quantum information applications. While conditional preparation is a highly successful approach to p…
Heralding multiple photonic pulsed Bell-pairs via frequency-resolved entanglement swapping
Sofiane Merkouche, Valérian Thiel, Alex O. C. Davis +1
Entanglement is a unique property of quantum systems and an essential resource for many quantum technologies. The ability to transfer or swap entanglement between systems is an imp…
Single-photon characterization by two-photon spectral interferometry
Valérian Thiel, Alex O. C. Davis, Ke Sun +3
Single-photon sources are a fundamental resource in quantum optics. The indistinguishability and purity of photons emitted from different sources are crucial (necessary, essential)…
Two-color Bell states heralded via entanglement swapping
Sofiane Merkouche, Valérian Thiel, Alex O. C. Davis +1
We report on an experiment demonstrating entanglement swapping of time-frequency entangled photons. We perform a frequency-resolved Bell-state measurement on the idler photons from…
Measuring the quantum state of a photon pair entangled in frequency and time
Alex O. C. Davis, Valerian Thiel, Brian J. Smith
We present a technique to completely characterise the spectral-temporal wave function of a broadband photon pair using spectral-shearing interferometry. Our method is fully self-re…
Measuring the single-photon temporal-spectral wave function
Alex O. C. Davis, Valérian Thiel, Michał Karpiński +1
Temporal-spectral modes of light provide a fundamental window into the nature of atomic and molecular systems and offer robust means for information encoding. Methods to precisely…
Pulsed single-photon spectrometer by frequency-to-time mapping using chirped fiber Bragg gratings
Alex O. C. Davis, Paul M. Saulnier, Michal Karpinski +1
A fiber-integrated spectrometer for single-photon pulses outside the telecommunications wavelength range based upon frequency-to-time mapping, implemented by chromatic group delay…
