Title: Neutron Detection and Center-of-Mass Motion Extraction for SRC Studies in Helium-4

Abstract: This seminar presents results from a CLAS12-based study of short-range nucleon–nucleon correlations (SRCs). The first part describes a neutron-identification algorithm used to select SRC-dominated events in electron scattering data. The second part presents updated measurements of the center-of-mass momentum distribution of two-nucleon correlations in helium-4, extending and improving upon previous experimental results.

Second speaker: Amir Yona

Title: Quantum Key Distribution via Charge Teleportation

Abstract: Quantum information theory fundamentally reshapes our understanding of communication by harnessing entanglement as a resource. One of its most critical applications is Quantum Key Distribution (QKD), which promises theoretically unbreakable security to counter the growing vulnerabilities of classical encryption. This talk introduces a novel QKD primitive inspired by Quantum Energy Teleportation (QET)—a protocol where local operations on an entangled ground state allow energy to be extracted at a distant location. We extend this concept to charge teleportation, demonstrating how Alice can remotely steer the sign of a local charge shift at Bob’s end to directly encode a cryptographic key.
