Generating quantum entanglement from sunlight
Cheng Li, Jasvinder Brar, Michael Küblböck +4
Energy consumption is becoming a serious bottleneck for integrating quantum technologies within the existing global information infrastructure. In photonic architectures, considera…
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…
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…
