I am happy to see this article published in PRR!

"Quantum time" ideas from quantum foundations → parallel-in-time algorithms where ancilla qubits represent time itself 🕑

I am so, so happy to see this article published as a perspective in Nature Communications:

More than the paper itself, I thoroughly enjoyed chatting with all my co-authors on the implications of the absence of BPs ~ classical simulability connection

We recently posted 2 works on quantum resource theories: arxiv.org/abs/2506.19696, arxiv.org/abs/2507.10851

👂Huh? Yall want more? We got you covered with a NEW work

Analyzing the free states of one quantum resource theory as resource states of another

arxiv.org/abs/2507.11793

We prove that CFOs are genuine free operations mapping free states to free states. We also discuss CFOs channels and provide strong numerical evidence that these channels do not increase resources on average, just as in SLOCC!

CFOs are defined by a complexification of standard unitary free operations, and extends the intuition of SLOCC to Lie algebraic structures. The "phone call" in fermions for example!

An important consequence of our framework, is that we can now import tools from one QRT onto another. In the second part of the paper we showcase this by defining a new set of free operations: complexified free operations (CFOs).

In this work we show that QRTs can be defined in terms
of some preferred algebraic structure E that must be
preserved. The free operations follow as automorphisms of E, which in turn leads to natural notions of free states. This unifies so many different QRTs!

The very concept of "resource" depends on operational constraints. This makes it difficult to unify different QRTs under a common framework. E.g., while the concept of locality is very clear in a QRT of entanglement, what is the equivalent of phone calls in a QRT of fermions?

Quantum resource theories (QRTs) are a central tool of quantum information developed to acknowledge the fact that different quantum operations and states of a given system are more valuable than others.

We provide a unifying framework leading to new free operations 🧵⬇️

Great conference at Genoa, Italy about "Time in Quantum Theory" (TIQT)😀

I'll use the ocasion to share my related seminar doi.org/10.52843/cas... on our recent paper "Path Integrals from spacetime quantum actions" (doi.org/10.1016/j.ao...).

The topic? Unifying "Quantum time" and Feynman's approach

🚨Excited to share our new paper "Characterizing quantum resourcefulness via group-Fourier decompositions" from last year's LANL Quantum Computing summer School📘 arxiv.org/abs/2506.19696 !

New paper out!! 🎉🎉

"Optimal Haar random fermionic linear optics circuits"

Super fun collaboration with @impolster.bsky.social @nahuelldiaz.bsky.social @martinlaroo.bsky.social and @mvscerezo.bsky.social !
