A positive operator-valued measure for two-photon detection via sum-frequency generation
Sofiane Merkouche, Valérian Thiel, Brian J. Smith
Spontaneous parametric down conversion (PDC), in the perturbative limit, can be considered as a probabilistic splitting of one input photon into two output photons. Conversely, sum…
Quantum-enhanced stimulated emission microscopy
Gil Triginer Garces, Helen M. Chrzanowski, Shakib Daryanoosh +6
Nonlinear optical microscopy techniques have emerged as a set of successful tools for biological imaging. Stimulated emission microscopy belongs to a small subset of pump-probe tec…
Quantum Enhanced Measurement of an Optical Frequency Comb
Y. Cai, J. Roslund, V. Thiel +2
Measuring the spectral properties of an optical frequency comb is among the most fundamental tasks of precision metrology. In contrast to general single-parameter measurement schem…
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…
