We derive an inequality relating the entropy difference between two quantum states to their trace norm distance, sharpening a well-known inequality due to M. Fannes. In our inequality, equality can be attained for every prescribed value of the trace norm distance.

Growth and collapse of subsystem complexity under random unitary circuits
Under random brickwork circuits, regions larger than half the system have complexity growing linearly in time, while a smaller region thermalizes to essentially zero complexity by T=ℓ/2 — with holographic and replica ...

The entropic coherence is a necessary resource for non-energy preserving gates
Entropic coherence of a battery, the relative entropy between its state and its energy-dephased version, must grow at least as the logarithm of the desired gate precision, making finite-dimensional batteries fundament...

Growth and collapse of subsystem complexity under random unitary circuits
In random unitary circuits, small-subsystem complexity grows linearly up to time ℓ/2 then collapses to zero while complementary large subsystems grow for exponentially long times.

SharedRep-RLHF: A Shared Representation Approach to RLHF with Diverse Preferences
SharedRep-RLHF learns a shared preference representation across groups to improve worst-case reward estimates for minority annotators, but the theoretical guarantees are undermined by proof errors.
