Simultaneous amplitude and phase spectroscopy using two-photon interference
Kyle M. Jordan, Yingwen Zhang, Frédéric Bouchard +5
Quantum spectroscopy seeks to probe chemical systems using nonclassical light, which has properties that are qualitatively and quantitatively different than conventional light sour…
Ultrafast switching of telecom photon-number states
Kate L. Fenwick, Frédéric Bouchard, Alicia Sit +7
A crucial component of photonic quantum information processing platforms is the ability to modulate, route, convert, and switch quantum states of light noiselessly with low inserti…
Accurate Unsupervised Photon Counting from Transition Edge Sensor Signals
Nicolas Dalbec-Constant, Guillaume Thekkadath, Duncan England +3
We compare methods for signal classification applied to voltage traces from transition-edge sensors (TES) which are photon-number resolving detectors fundamental for accessing quan…
Broadband spectral manipulation of single photons using cross-phase modulation
Kate L. Fenwick, Frédéric Bouchard, Guillaume Thekkadath +3
Manipulating the frequency and bandwidth of light is crucial in classical and quantum applications including communication, spectroscopy, imaging, and signal processing. Such capab…
Imaging at the quantum limit with convolutional neural networks
Andrew H. Proppe, Aaron Z. Goldberg, Guillaume Thekkadath +8
Deep neural networks have been shown to achieve exceptional performance for computer vision tasks like image recognition, segmentation, and reconstruction or denoising. Here, we ev…
Ultrafast all-optical modulation of spatially structured photons
Alicia Sit, Frédéric Bouchard, Nicolas Couture +4
Manipulating the structure of single photons in the ultrafast domain is enabling new quantum information processing technologies. At the picosecond timescale, quantum information c…
