Quantum Cellular Automata on a Dual-Species Rydberg Processor
Ryan White, Vikram Ramesh, Alexander Impertro +6
As quantum devices scale to larger and larger sizes, a significant challenge emerges in scaling their coherent controls accordingly. Quantum cellular automata (QCAs) constitute a p…
High-fidelity entanglement and coherent multi-qubit mapping in an atom array
Aruku Senoo, Alexander Baumgärtner, Joanna W. Lis +5
Neutral atoms in optical tweezer arrays possess broad applicability for quantum information science, in computing, simulation, and metrology. Among atomic species, Ytterbium-171 is…
Adiabatic echo protocols for robust quantum many-body state preparation
Zhongda Zeng, Giuliano Giudici, Aruku Senoo +3
Entangled many-body states are a key resource for quantum technologies. Yet their preparation through analog control of interacting quantum systems is often hindered by experimenta…
Fast entangling gates for Rydberg atoms via resonant dipole-dipole interaction
Giuliano Giudici, Stefano Veroni, Giacomo Giudice +2
The advent of digital neutral-atom quantum computers relies on the development of fast and robust protocols for high-fidelity quantum operations. In this work, we introduce a novel…
Learning symmetry-protected topological order from trapped-ion experiments
Nicolas Sadoune, Ivan Pogorelov, Claire L. Edmunds +6
Classical machine learning has proven remarkably useful in post-processing quantum data, yet typical learning algorithms often require prior training to be effective. In this work,…
Quantum dimer models with Rydberg gadgets
Zhongda Zeng, Giuliano Giudici, Hannes Pichler
The Rydberg blockade mechanism is an important ingredient in quantum simulators based on neutral atom arrays. It enables the emergence of a rich variety of quantum phases of matter…
Variational manifolds for ground states and scarred dynamics of blockade-constrained spin models on two and three dimensional lattices
Joey Li, Giuliano Giudici, Hannes Pichler
We introduce a variational manifold of simple tensor network states for the study of a family of constrained models that describe spin-1/2 systems as realized by Rydberg atom array…
Integrable Digital Quantum Simulation: Generalized Gibbs Ensembles and Trotter Transitions
Eric Vernier, Bruno Bertini, Giuliano Giudici +1
The Trotter-Suzuki decomposition is a promising avenue for digital quantum simulation (DQS), approximating continuous-time dynamics by discrete Trotter steps of duration . Recen…
Unsupervised Interpretable Learning of Phases From Many-Qubit Systems
Nicolas Sadoune, Giuliano Giudici, Ke Liu +1
Experimental progress in qubit manufacturing calls for the development of new theoretical tools to analyze quantum data. We show how an unsupervised machine-learning technique can…
Trimer states with topological order in Rydberg atom arrays
Giacomo Giudice, Federica Maria Surace, Hannes Pichler +1
Trimers are defined as two adjacent edges on a graph. We study the quantum states obtained as equal-weight superpositions of all trimer coverings of a lattice, with the constraint…
Dynamical preparation of quantum spin liquids in Rydberg atom arrays
Giuliano Giudici, Mikhail D. Lukin, Hannes Pichler
We theoretically analyze recent experiments [G. Semeghini et al., Science 374, 1242 (2021)] demonstrating the onset of a topological spin liquid using a programmable quantum simula…
Tunneling in projective quantum Monte Carlo simulations with guiding wave functions
T. Parolini, E. M. Inack, G. Giudici +1
Quantum tunneling is a valuable resource exploited by quantum annealers to solve complex optimization problems. Tunneling events also occur during projective quantum Monte Carlo (P…
Entanglement guided search for parent Hamiltonians
X. Turkeshi, T. Mendes-Santos, G. Giudici +1
We introduce a method for the search of parent Hamiltonians of input wave-functions based on the structure of their reduced density matrix. The two key elements of our recipe are a…
