Attosecond delay metrology beyond the photon coherence time with spectrally resolved Hong-Ou-Mandel interferometry
Yingwen Zhang, Kyle Jordan, Duncan England +3
Hong-Ou-Mandel (HOM) interferometry enables delay estimation at the quantum precision limit but is traditionally constrained to path differences within the coherence time of the in…
Full-field mapping of spatially varying polarization entanglement generated from spontaneous parametric down-conversion
Cheng Li, Girish Kulkarni, Isaac Soward +6
Two-photon states generated from spontaneous parametric down-conversion (SPDC) can display entanglement in all degrees of freedom (DoFs) of light, including spatial, temporal, and…
Demonstration of a reconfigurable quantum network architecture suitable for ground-to-space communication
Stéphane Vinet, Duncan England, Chang-qing Xu +1
We experimentally demonstrate a reconfigurable quantum network architecture suitable for integrating satellite links in metropolitan quantum networks. The network architecture is d…
Quantum Optical Techniques for Biomedical Imaging
Vahid Salari, Yingwen Zhang, Sepideh Ahmadi +7
Quantum imaging is emerging as a transformative approach for biomedical applications, applying nonclassical properties of light, such as entanglement, squeezing, and quantum correl…
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…
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…
