Quantum pseudoentanglement
Entanglement is a quantum resource, in some ways analogous to randomness in classical
computation. Inspired by recent work of Gheorghiu and Hoban, we define the notion of" …

Black box work extraction and composite hypothesis testing
Work extraction is one of the most central processes in quantum thermodynamics. However,
the prior analysis of optimal extractable work has been restricted to a limited operational …

[PDF][PDF] A little magic means a lot
Notions of so-called magic quantify how non-classical quantum states are in a precise
sense: low values of magic preclude quantum advantage; they also play a key role in …

Pseudorandom isometries
We introduce a new notion called Q-secure pseudorandom isometries (PRI). A
