The only thing that could possibly be hotter than Italian twins explaining entanglement in Italian is Italian triplets explaining the GHZ state.
Happy to share our TEDx talk where me and my twin @antonioannamele.bsky.social chat about quantum technologies!

The saga of *quantum learning theory with CV systems* never ends!
And indeed, when you look closely at this field, many natural and promising questions arise. For instance:
How to learn CV Gaussian unitaries?

We show that deciding whether a given dataset, formed by a few Majorana correlation functions estimates, can be consistent with a free-fermionic state is an NP-complete problem.

We show that ‘typical’ noisy circuits can be efficiently simulated classically for any local noise and circuit architecture — in contrast to fault-tolerantly designed noisy circuits. ⚡️

In arXiv:2501.13101, we explore a broad class of noisy circuits across all geometries, significantly relaxing the strict assumptions on geometric locality and noise models imposed by prior works.
