Entanglement Cost of Discriminating Quantum States Under Locality Constraints
Date:
This presentation—delivered by my co-author—introduced our recent results on the entanglement cost required to discriminate quantum states when operations are restricted by locality constraints, focusing on:
- Introduction of spectral PPT-distance as a lower bound on entanglement cost using PPT POVMs;
- Derivation of upper bounds, proving that a single Bell state suffices for optimally discriminating a pure state against any other state;
- Applications in quantum data hiding, distributed quantum sensing, and the resource cost of implementing measurements under LOCC constraints.
