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…
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…
Quantum enhanced beam tracking surpassing the Heisenberg uncertainty limit
Yingwen Zhang, Duncan England, Noah Lupu-Gladstein +5
Determining a beam's full trajectory requires tracking both its position and momentum (angular) information. However, the product of position and momentum uncertainty in a simultan…
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…
