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…
Quantitative phase gradient microscopy with spatially entangled photons
Yingwen Zhang, Paul-Antoine Moreau, Duncan England +2
We present an entanglement-based quantitative phase gradient microscopy technique that employs principles from quantum ghost imaging and ghost diffraction. In this method, a transp…
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…
Diffraction of correlated biphotons through transparent samples
Nazanin Dehghan, Alessio D'Errico, Yingwen Zhang +2
Two-photon states generated through degenerate spontaneous parametric down-conversion (SPDC) can exhibit sharp correlations in the transverse spatial coordinates. This property lea…
