SUMMARY:Quantum computational enhanced optical imaging\, R. G. Herb Co
 ndensed Matter Seminar\, Johannes Borregaard\, Harvard
DESCRIPTION:High-resolution optical imaging underpins applications fro
 m exoplanet detection and satellite monitoring to molecular imaging. C
 lassical methods rely on tomographic reconstruction and post-processin
 g to remove background noise\, which comes with prohibitive measuremen
 t overhead and stability requirements for weak sources. In this talk\,
  I will introduce a fundamentally different approach that replaces tom
 ographic analysis with direct quantum processing of photonic informati
 on. Building on recent demonstrations of coherent photon-to-qubit tran
 sduction (arXiv:2509.09464)\,  asynchronously arriving photons can be 
 stored in quantum memories and interfered through quantum algorithms t
 o remove background noise without tomographic reconstruction. Applied 
 to exoplanet imaging\, our estimates show several-orders-of-magnitude 
 improvement under realistic conditions using quantum circuits of only 
 hundreds of gates and tens of qubits. The approach generalizes to othe
 r tasks such as molecular imaging\, satellite monitoring\, and adaptiv
 e optics\, opening new opportunities for quantum-enhanced imaging with
  near term quantum computers.
