This new technique turns out to be very powerful, also allowing us to recover the tight lower bound for mixedness testing using just a few elementary calculations!

We prove our lower bounds using a new quantum analogue of the Ingster-Suslina method. Essentially, we find a convenient way to decompose the quantum Ο^2 divergence between a mixture of states and a fixed reference state.

New work with @booleananalysis.bsky.social! We prove instance-optimal bounds for quantum state certification when testers can measure all copies simultaneously, finding that the optimal copy complexity depends on how close to maximally mixed the hypothesis state is.
