Improved Spatial Resolution Achieved by Chromatic Intensity Interferometry
Lu-Chuan Liu, Luo-Yuan Qu, Cheng Wu +8
Interferometers are widely used in imaging technologies to achieve enhanced spatial resolution, but require that the incoming photons be indistinguishable. In previous work, we bui…

Chromatic interferometry with small frequency differences
Luo-Yuan Qu, Lu-Chuan Liu, Jordan Cotler +9
By developing a `two-crystal' method for color erasure, we can broaden the scope of chromatic interferometry to include optical photons whose frequency difference falls outside of…

Color Erasure Detectors Enable Chromatic Interferometry
Luo-Yuan Qu, Jordan Cotler, Fei Ma +7
By engineering and manipulating quantum entanglement between incoming photons and experimental apparatus, we construct single-photon detectors which cannot distinguish between phot…
