Variational quantum simulation of U(1) lattice gauge theories with qudit systems, Pavel P. Popov et al Pavel Popov ICFO Martin Ringbauer @[email protected] Hauke Group Università di Trento #Quantum go.aps.org/3SScpqc

When can chaotic many-body quantum states with symmetries be used for higher-order state designs? We answer this question by establishing a sufficient condition. Take a look at arxiv.org/abs/2402.08949 Dileep Varikuti

Simulating transport in quantum devices is challenging but tensor network techniques provide powerful numerical tools to tackle these phenomena. Discover more at journals.aps.org/prb/abstract/1… and journals.aps.org/prb/abstract/1…

Here are some snapshots from the 'MUSE out-of-hours' event at MUSE_Museum. Last Thursday, we had the pleasure of engaging with the public on the topic of Quantum Computing. We are grateful to the museum for the invitation!

We unveil the effects of interaction induced processes on the miscibility-immiscibility transition of strongly interacting ultracold bosons in optical lattices. Take a look at arXiv:2403.14601 arxiv.org/abs/2403.14601

The NeQST project, a collaboration between 8 universities and institutions coordinated by Università di Trento, has reached the halfway point. We had a highly stimulating meeting at HRI-EU, Offenbach, to review progress and plan for the next 18 months! #HorizonEurope

How much does the non-Hermiticity of the Hamiltonian get translated to the behavior of single and many-particle quantum properties of the system? We tried to find an answer to this in our recent article:  arXiv:2406.13517

New preprint online! In this paper, we examine how Qudits can be used in quantum circuits in order to include inequality constraints in Quantum Optimization routines. arxiv.org/abs/2410.07674

New preprint out on the arxiv! In this collaboration with the NQUIRE Center, we study how counterdibaticity and symmetries can be exploited together in the framework of qudit variational algorithms in order to obtain shallower circuits. arxiv.org/abs/2410.06710

Multipartite Entanglement grows to a maximum in the quantum optimization and then reduces to a lower value, creating an entanglement barrier that bounds the quantum algorithm's success. Read more at arXiv: arxiv.org/pdf/2411.08119.

Can the post-selection technique be extended to non-Abelian Lattice Gauge Theories? We answered positively in our new pre-print paper arxiv.org/abs/2412.07844, where we studied two different methods.

Thrilled to announce our latest paper: arxiv.org/pdf/2412.14280. Through the spectral form factor, we explore how distance-dependent interactions and single-particle criticality shape many-body spectral statistics. Wishing everyone a joyful holiday season!🎄

Our paper “The Moments of the Spectral Form Factor in SYK” is now online! arxiv.org/pdf/2412.18737 We study the noise in the spectral form factor of the SYK model, revealing deviations from random matrix universality that become more pronounced in sparse and quadratic models.

The call for PhD fellowships in Physics at Università di Trento is now open: tinyurl.com/y5p5paxc We have one position open to work on Hamiltonian Learning (scholarship K), with Honda Research Institute #hri. Candidates can also apply for scholarships sponsored by UniTrento and INFN.

Complexity isn’t one-size-fits-all! We show how different markers—fractal dimension, entanglement entropy, stabilizer Rényi entropy— detect distinct transitions in systems undergoing localization transition, revealing new phases. 👉 arxiv.org/abs/2505.09707
