Quantum Teleportation
Quantum teleportation is a process by which the state of a quantum system (a qubit) can be transmitted from one location to another without physically sending the particle itself. Quantum teleportation has become a foundational method in quantum communication, envisioned…

Query Attacks Buy Reconnaissance
NIST lists query access as an attacker capability, and three different attacks reach a model through it. Where the model makes a security decision, extraction is not the loss. It is reconnaissance for the evasion that follows.
