Complexity of quantum tomography from genuine non-Gaussian entanglement - Nature Communications
The interplay between properties of quantum correlation and learning sample complexity in bosonic quantum systems is currently unclear. The authors prove efficient learning for broad classes of non-Ga...

Given a mixed state, one can always write down its purifications. However, the “purification operation” is unphysical, i.e. it cannot be realised via a quantum channel.

This is a publication I am extremely happy about. It is a bit rebellious, and yet it touches upon an old and important question: How can we learn an unknown continuous quantum state from data?
www.nature.com/articles/s41...
We prove that quantum state tomography is a lot harder than anticipated.

The only thing that could possibly be hotter than Italian twins explaining entanglement in Italian is Italian triplets explaining the GHZ state.

Okay, last post on *quantum learning theory with CV systems* (for a few months🫣) Today's new work tackles another natural and central question in this rapidly developing field: Given an unknown CV state, how to test whether is it Gaussian or not?

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?

I’d like to advertise two cute technical results of today’s paper that may be of independent interest (I hope): A new decomposition of Gaussian unitaries and new bosonic trace distance bounds (the saga of bosonic trace distance bounds never ends! 😍)

New bosonic paper out! Take the covariance matrix of a pure state and count the number of symplectic eigenvalues that are strictly larger than one: this is a powerful non-Gaussian monotone — the *symplectic rank*

New paper out today on "Q Thermo with CV systems"! What is the maximum energy that you can extract from a quantum state via Gaussian unitaries only? We solve this problem by establishing a simple, cute formula for the *Gaussian ergotropy*. 1/

New paper out! We study one-shot q communication over reasonable non-Markovian lossy Gaussian channels. To do so, we prove error bounds on the convergence rate of the *powerful* Avram-Parter's (and Szego's) theorem, which may be of independent interest in matrix analysis.
