Alejandro Sopena

¡Nuevo doctor en el IFT! El pasado viernes, Alejandro Sopena leyó con gran éxito su tesis doctoral titulada 'Design and implementation of quantum algorithms in the noisy intermediate scale quantum era' Y a nosotros nos llena de orgullo, ¡felicidades!🥳 #PhD #PhDlife

I am offering a 4 year PhD position to work on quantum algorithms for many-body problems, to stat in Winter of 2025. Please do forward the announcement to potentially interested candidates! ift.uam-csic.es/en/jobs/phd-po…

@Alessdip @qZoeHolmes @GrosQmichi Thanks!

@QuantumOktopus @qZoeHolmes @GrosQmichi Hi Alejandro, I have asked the editor in chief to solve the problem. Thanks for spotting this!

✴️Quantum Machine Intelligence special issue for QTML 2023 ✴️ Submission deadline April 1st. Work not presented at QTML can also be submitted. Submit here: www2.cloud.editorialmanager.com/qumi/default2.… and select “SI: QTML 2023: Quantum Techniques in Machine Learning”. @Alessdip @GrosQmichi

🎓 Congrats, Dr. Max Hunter-Gordon, on successfully defending your thesis 'Algorithmic Techniques for Noisy Intermediate Scale Quantum Computers.' 🥳 Hurray!!!! #PhD #QuantumComputing

New preprint out now 💥 arxiv.org/abs/2311.05680 We present a novel real-time quantum error mitigation strategy which can be used to improve trainability of variational quantum algorithms. Thanks to my collaborators: @QuantumOktopus, Andrea Papaluca and Stefano Carrazza.

New paper out today!! 🔥 Bethe Ansatz ---> Quantum Circuit arxiv.org/abs/2309.14430 Thanks to Roberto, @MaxHunterGordon , Germán and Esperanza for a great collaboration.

Hoy felicitamos a Diego García-Martín, que se ha convertido en doctor tras defender su tesis supervisada por Germán Sierra y José Ignacio Latorre 👏👏👏 ¡Enhorabuena!

@kosmikakapo @eurekakutxa Si que ha llegado lejos la wilberfuerza

Thanks to @eurekakutxa for organizing the activity "Encuentro de Vidas Científicas" and uploading all the talks (including mine, see minute 34:25) to YouTube!! youtube.com/watch?v=TmRp50…

Suuuuuper happy to announce that this work is finally out! 😁 I have just thought that maybe it would be cool if I wrote a thread summing up what we've being doing, so here I go. I will try to keep it brief (I talk a lot). A thread🧵 (1/n)

Really happy to announce that I will be giving a talk at the Quantum Matter 2022 (@QuantumConf) on the "Algebraic Bethe Circuits" 🙂 Presenting work in collaboration with @QuantumOktopus, @MaxHunterGordon , Germán Sierra & Esperanza López arxiv.org/abs/2202.04673

We run small-scale error-mitigated implementations on the IBM quantum computers, including the preparation of the ground state for the XX and XXZ models in 4 sites.

We illustrate our method in the spin- 1/2 XX and XXZ models and we find its application on the XX model is efficient. We run numerical simulations, preparing eigenstates of the XXZ model for systems of up to 24 qubits and 12 magnons.

Very happy to announce that our new paper on the Algrebaic Bethe Ansatz (ABA) on quantum computers is finally on arXiv!! Read and enjoy it [THREAD] arxiv.org/abs/2202.04673
