Optimized Matrix-Product State Simulations of Quantum Error Correction Circuits
Asier Piñeiro Orioli, Chen Zhao, Guido Masella +3
Simulating quantum error correction (QEC) circuits including non-Clifford gates at scale is important to accelerate progress toward fault-tolerant quantum computing. Here we demons…
Tuning Quantum MPS
Anna Leonteva, Maxime Outteryck, Guido Masella
Matrix Product State (MPS) methods are among the most effective approaches for the classical simulation of quantum circuits, but their practical performance depends strongly on sim…
K-ADAPT-VQE: Optimizing Molecular Ground State Searches by Chunking Operators
Tatiana A. Bespalova, Oumaya Ladhari, Guido Masella
Classical simulation of molecular systems is limited by exponential scaling, a hurdle quantum algorithms like Variational Quantum Eigensolvers (VQEs) aim to overcome. Although ADAP…
Scale-invariant phase transition of disordered bosons in one dimension
Tanul Gupta, Guido Masella, Francesco Mattiotti +2
The disorder-induced quantum phase transition between superfluid and non-superfluid states of bosonic particles in one dimension is generally expected to be of the Berezinskii-Kost…
Anti-Drude Metal of Bosons
Guido Masella, Nikolay V. Prokof'ev, Guido Pupillo
In the absence of frustration, interacting bosons in the ground state exist either in the superfluid or insulating phases. Superfluidity corresponds to frictionless flow of the mat…
Universal algebraic growth of entanglement entropy in many-body localized systems with power-law interactions
Xiaolong Deng, Guido Masella, Guido Pupillo +1
Power-law interactions play a key role in a large variety of physical systems. In the presence of disorder, these systems may undergo many-body localization for a sufficiently larg…
Ultrafast creation of overlapping Rydberg electrons in an atomic BEC and Mott-insulator lattice
Michiteru Mizoguchi, Yichi Zhang, Masaya Kunimi +13
An array of ultracold atoms in an optical lattice (Mott insulator) excited to a state where single electron wave-functions spatially overlap would represent a new and ideal platfor…
Effects of energy extensivity on the quantum phases of long-range interacting systems
Thomas Botzung, David Hagenmüller, Guido Masella +4
We investigate the ground state properties of one-dimensional hard-core bosons interacting via a variable long-range potential using the density matrix renormalization group. We de…
Supersolid stripe crystal from finite-range interactions on a lattice
Guido Masella, Adriano Angelone, Fabio Mezzacapo +2
Strong, long-range interactions present a unique challenge for the theoretical investigation of quantum many-body lattice models, due to the generation of large numbers of competin…
De-excitation spectroscopy of strongly interacting Rydberg gases
C. Simonelli, M. Archimi, L. Asteria +5
We present experimental results on the controlled de-excitation of Rydberg states in a cold gas of Rb atoms. The effect of the van der Waals interactions between the Rydberg atoms…
A new setup for experiments with ultracold Dysprosium atoms
E. Lucioni, G. Masella, A. Fregosi +7
In the domain of quantum degenerate atomic gases, much interest has been raised recently by the use of Lanthanide atoms with large magnetic moments, in particular Dysprosium and Er…
Seeded excitation avalanches in off-resonantly driven Rydberg gases
Cristiano Simonelli, Maria Martinez Valado, Guido Masella +4
We report an experimental investigation of the facilitated excitation dynamics in off-resonantly driven Rydberg gases by separating the initial off-resonant excitation phase from t…
Van der Waals explosion of cold Rydberg clusters
R. Faoro, C. Simonelli, M. Archimi +6
We report on the direct measurement in real space of the effect of the van der Waals forces between individual Rydberg atoms on their external degrees of freedom. Clusters of Rydbe…
