  • Topological Holography for Mixed-State Phases and Phase Transitions

    Author(s): Ran Luo, Yi-Nan Wang, and Zhen Bi Extending symmetry topological field theory to open quantum systems enables a systematic classification of mixed-state quantum phases and their transitions. [PRX Quantum 6, 040358] Published Mon Dec 08, 2025

  • Composable Framework for Device-Independent State Certification

    Author(s): Rutvij Bhavsar, Lewis Wooltorton, and Joonwoo Bae A quantum state-certification protocol works without trusting the devices and ensures that the certified states can be securely reused across other quantum protocols, paving the way for scalable and modular quantum networks.
