Higher-order Symmetric Quantum Mpemba Effect in Fragmented Systems
Sreemayee Aditya, Sara Murciano, Xhek Turkeshi
A quantum system can restore a broken symmetry faster the more strongly it initially breaks it, an anomaly known as the quantum Mpemba effect. Whether this effect survives once con…
Quantum Fisher Information under decoherence with explicit wavefunctions
Francesco Musso, Vittorio Vitale, Sara Murciano
We present a method to estimate the quantum Fisher information (QFI) of many-body quantum states in the presence of decoherence, where its direct evaluation requires the full spect…
An asymmetry lower bound on fermionic non-Gaussianity
Filiberto Ares, Michele Mazzoni, Sara Murciano +3
Fermionic Gaussian states are a fundamental tool in many-body physics, faithfully representing non-interacting quantum systems and allowing for efficient numerical simulations. Giv…
Quantum logic control and entanglement in hybrid atom-molecule arrays
Chi Zhang, Sara Murciano, Nathanan Tantivasadakarn +1
Polar molecules, with their rich internal structure, offer immense potential for fundamental physics, quantum technology, and controlled chemistry. However, their utilization is cu…
Experimental observation of conformal field theory spectra
Xiangkai Sun, Yuan Le, Stephen Naus +6
Conformal field theories (CFTs) feature prominently in high-energy physics, statistical mechanics, and condensed matter. For example, CFTs govern emergent universal properties of s…
Quantum sensing with critical systems: impact of symmetry, imperfections, and decoherence
Yinan Chen, Sara Murciano, Pablo Sala +1
Entangled many-body states enable high-precision quantum sensing beyond the standard quantum limit. We develop interferometric sensing protocols based on quantum critical wavefunct…
Universal properties of the many-body Lanczos algorithm at finite size
Luca Capizzi, Leonardo Mazza, Sara Murciano
We study the universal properties of the Lanczos algorithm applied to finite-size many-body quantum systems. Focusing on autocorrelation functions of local operators and on their i…
Practical roadmap to measurement-altered criticality in Rydberg arrays
Stephen Naus, Yue Liu, Sara Murciano +3
Weak measurements have been predicted to dramatically alter universal properties of quantum critical wavefunctions, though experimental validation remains an open problem. Here we…
Measurement-induced symmetry restoration and quantum Mpemba effect
Giuseppe Di Giulio, Xhek Turkeshi, Sara Murciano
Monitoring a quantum system can profoundly alter its dynamical properties, leading to nontrivial emergent phenomena. In this work, we demonstrate that dynamical measurements strong…
Boundary transitions from a single round of measurements on gapless quantum states
Yue Liu, Sara Murciano, David F. Mross +1
Measurements can qualitatively alter correlations and entanglement emerging in gapless quantum matter. We show how a single round of measurements on gapless quantum systems can, up…
On symmetry-resolved generalized entropies
Fei Yan, Sara Murciano, Pasquale Calabrese +1
Symmetry-resolved entanglement, capturing the refined structure of quantum entanglement in systems with global symmetries, has attracted a lot of attention recently. In this manusc…
Observable-projected ensembles
Alexey Milekhin, Sara Murciano
Measurements in many-body quantum systems can generate non-trivial phenomena, such as preparation of long-range entangled states, dynamical phase transitions, or measurement-altere…
Quantum criticality under imperfect teleportation
Pablo Sala, Sara Murciano, Yue Liu +1
Entanglement, measurement, and classical communication together enable teleportation of quantum states between distant parties, in principle with perfect fidelity. To what extent d…
Observing the quantum Mpemba effect in quantum simulations
Lata Kh Joshi, Johannes Franke, Aniket Rath +9
The non-equilibrium physics of many-body quantum systems harbors various unconventional phenomena. In this study, we experimentally investigate one of the most puzzling of these ph…
Entanglement barrier and its symmetry resolution: theory and experiment
Aniket Rath, Vittorio Vitale, Sara Murciano +6
The operator entanglement (OE) is a key quantifier of the complexity of a reduced density matrix. In out-of-equilibrium situations, e.g. after a quantum quench of a product state,…
