If we can understand it, is it quantum?

That’s right

A moratorium on “paving the way”.

What a difference there is between two and one. Three and two are a world apart. Four and three are almost the same, and so on.

Quantum $f$-divergences and Their Local Behaviour: An Analysis via Relative Expansion Coefficients Any reasonable measure of distinguishability of quantum states must satisfy a data processing inequality, that is, it must not increase under the action of a quantum channel. We can ask about the prop...

A note on commutators in algebras of unbounded operators We show that the identity is the sum of two commutators in the algebra of all operators affiliated with a von Neumann algebra of type II$_1$, settling a question, in the negative, that had puzzled a n...

To be short, then, a whale is a spouting fish with a horizontal tail. There you have him.

Prof. Debbie Leung, at the lectern, in front of a slide giving an example of quantum channels whose capacity is strictly superadditive

Very nice plenary talk at #ITW2025 by Debbie Leung (@debbie-leung-q.bsky.social) on (non)-additivity of quantum channel capacity.

Some much there is unknown—or just completely weird!

what is it that makes the front of a man—what, indeed, but his eyes?

black silhouetted mountains on the bottom of the frame, black silhouetted leaves from a cottonwood poking into the frame in the foreground, a pale grey blue sky with a tiny sliver of the moon visible and one bright dot of light above it. between the mountains and the moon, the sky is filled with deep purple clouds that are lit up a phosphorescent pink on their undersides.

Measuring Multiparticle Indistinguishability with the Generalized Bunching Probability The indistinguishability of many bosons undergoing passive linear transformations followed by number basis measurements is fully characterized by its visible state. However, measuring all of the param...

Excited to share our new paper! We prove that Lieb’s permanental dominance conjecture, which has been open for over half a century, is equivalent to a certain conjecture about the bunching behavior of bosons.
