Generating quantum entanglement from sunlight
Cheng Li, Jasvinder Brar, Michael Küblböck +3
Energy consumption is becoming a serious bottleneck for integrating quantum technologies within the existing global information infrastructure. In photonic architectures, considera…
Violation of local realism with spatially multimode parametric down-conversion pumped by spatially incoherent light
Cheng Li, Jeremy Upham, Boris Braverman +1
We experimentally demonstrate a violation of local realism with highly spatially multimode polarization-entangled two-photon states produced by spontaneous parametric down-conversi…
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…
Fast control of the transverse structure of a light beam using acousto-optic modulators
Mahdieh Chartab Jabbari, Cheng Li, Xialin Liu +4
Fast, reprogrammable control over the transverse structure of light beams plays an essential role in applications such as structured illumination microscopy, optical trapping, and…
