The lab's official press release, with direct quotes: "Despite extensive research, the connection between a jet's initial conditions and its final particle distribution has remained elusive," said Naïm. "This study, for the first time, establishes a direct connection between the 'entanglement entropy' at the earliest stage of jet formation and the particles that emerge as a jet evolves." Funded by CFNS, DOE Office of Science, the Co-design Center for Quantum Advantage, and a BNL LDRD project.

Stony Brook's syndication of the same result, quoting Naïm on the significance of the finding and linking through to the full BNL story.

An in-depth interview piece, quoting Naïm as corresponding author: "Our study originated from the intriguing observation that the internal structure of protons at high energies exhibits maximal quantum entanglement," and detailing how ATLAS/LHC data were used to validate the theoretical framework linking fragmentation functions to hadron entropy.

Announcement of the completed proximity-focusing Ring Imaging Cherenkov (pfRICH) vessel — a carbon-fiber composite structure with an aramid honeycomb core — the result of a year-long project led by Charles-Joseph Naïm with graduate students Julian Driebeek, James Shirk, and Brynna Moran, and undergraduates Emmett Gebb, Saanvi Madishetty, and Mahmodol Mojumder.

A program accomplishment entry in the FY 2026 Congressional Justification (Volume 5, Science), citing the Stony Brook / BNL entanglement-hadronization work as an example of DOE-funded nuclear physics research: physicists used quantum computing methods to investigate the entanglement of quark jets, finding the jets are indeed entangled and that this entanglement is significantly affected by quark confinement — with implications for both physics experiments and near-term quantum-computing use.
