As a brief summary of the acknowledgements of my thesis, many thanks to everyone in the @nquirec.bsky.social group, colleagues (from the first to te last), collaborators, office mates and my supervisor. It has been a great time!

Last friday I finnaly got the chance to defend my PhD thesis "Scaling of Digital-Analog Quantum Computing". I see no better way to end this 5-year process than with a meme specially crafted for these times

Kudos to the authors of this paper for making this joke based on the main result of the paper. I chuckled a bit, 10/10 (from arXiv:2604.18699)

New paper on arxiv! This time is about the generalisation of digital-analog protocols to qudit systems, which maintains polynomial resource requirements as for the qubit case and allowing for more efficient mappings. Congrats to Alatz and to our supervisor @qmisanz.bsky.social. arXiv:2512.17697

The proof relies on the geometric properties of DAQC, which leads us to the surprisingly simple conclusion that the worst case scenario is found for the smallest non-trivial size, at the center of the faces of a tetrahedron. Side fun note: when I found the bound, this scene came to my mind instantly

New paper on arXiv! This one is about the maximum time requirement for Hamiltonian simulation using digital-analog, which is just linear with the number of couplings. This settles a long-standing open question and allows us to better understand DAQC's scaling requirements scirate.com/arxiv/2512.1...

The new protocol allow us to design a DAQC circuit to simulate an arbitrary two body Hamiltonian, which only requires O(n^3) classical computation time, compared with the O(exp(n)) of previous protocols. The result is a DAQC circuit with arbitrary SQR and suboptimal total circuit time.

We have published a new paper on arXiv. This one is about a new DAQC protocol for Hamiltonian simulation. This has been a nice colaboration between the quantum computing group at the DLR in germany and the UPV/EHU at the basque country. scirate.com/arxiv/2511.1...

It is always a pleasure to collaborate with Alberto, and the team with Pranav and @koushikphy.bsky.social worked so well together!

Happy to see the results of the collaboration between Philipp Hauke's group at UniTrento and @nquirec.bsky.social here at the @ehu.eus published on PRR. If you like to optimize your circuits using symmetries, you should take a look doi.org/10.1103/6ldg-3w1f

This extend the possible applicability of DAQC protocols in the near future with softer requirements on the noise scaling. While previously DAQC was envisioned as a practical way of working with NISQ devices, now it opens the door to efficient implementations for larger systems.

This work was possible with the support of Tecnalia, the UPV/EHU, the Max Plank Institute, the University of Vienna, Ikerbasque and BCAM. We also acknowledge the OpenSuperQ+100, the Ikur strategy proyects, and Basque and Austrian goverments support.

The downside however is that this error mitigation protocol requires a protocol with a larger total circuit time, thus, one need to decide if applying it is worth it or not.

Mikel Garcia de Andoin @mikelgda.bsky.social · 07/05/2025

What is even better, is that we have found a natural way of reducing these errors in DAQC protocols by targeting the interactions assumed that are 0 but could have some unwanted contribution.

Mikel Garcia de Andoin @mikelgda.bsky.social · 07/05/2025

As the interaction Hamiltonian is an important piece for DAQC, errors in its characterization affect the results of the circuit. We study this by bounding the errors in quantum simulation and in expectation value estimation tasks, and we find they can only grow polynomically with the system size.

Mikel Garcia de Andoin @mikelgda.bsky.social · 07/05/2025

For the ones not familiar with DAQC, it is a computational paradigm that employs the natural interaction Hamiltonian and single qubit gates to perform universal computations. This allows us to have the robustness of the analog paradigm while having the flexibility of gate-based quantum computing.

I think it would be a good time to reinstantiate the mirror network for the # arXiv. It’s an essential piece of the global research community in math, physics, computer-science and adjacent fields. Under the current circumstances it should not only be hosted in the US. #quantum #math #physics #cs
