Measurement-induced criticality for non-Abelian anyons: The monitored golden chain
Zhaohui Zhi, Bo Han, Romain Vasseur +3
Non-Abelian anyon chains whose interactions favor a single fusion channel host quantum critical ground states described by minimal-model conformal field theories (CFTs) protected b…
Theory of Measurement-Altered Criticality
Kabir Khanna, Sara Murciano, Romain Vasseur
Local measurements can alter long-range correlations in gapless quantum matter. We propose a theory of weakly-monitored Tomonaga-Luttinger liquids, a broad class of quantum critica…
Statistical Mechanics of Non-Abelian Learnability Transitions
Ruochen Ma, Romain Vasseur
Monitored many-body quantum systems can undergo sharp learnability transitions characterized by how much information can be learned by the observer. When the dynamics conserves a n…
Universal crossovers in weakly-monitored quantum critical states
Abhishek Kumar, Rushikesh A. Patil, Andreas W. W. Ludwig +1
We study post-measurement ensembles of ground states of tricritical and critical 1D quantum Ising Hamiltonians subjected, respectively, to weak energy and spin measurements without…
Post-selected Criticality in Measurement-induced Phase Transitions
Dolly Nambi, Kabir Khanna, Andrew Allocca +4
Information-theoretic phase transitions, such as the measurement-induced phase transition (MIPT), characterize the robustness of quantum dynamics to local monitoring and are natura…
Universal monitored dynamics in multimode bosonic systems
Shivam Patel, Catherine McCarthy, Ahana Chakraborty +5
We propose a route to study monitored many-body dynamics in multimode bosonic systems using circuit quantum electrodynamics. In this experimental setting, we construct several boso…
Anomalous Diffusion and Superdiffusion in Integrable Spin Chains via a Soliton Gas Mapping
Andrew Urilyon, Romain Vasseur, Sarang Gopalakrishnan +1
We introduce a multi-species soliton gas in which each species has a distinct effective scattering length, and the repulsive scattering shift is set by the smaller of the two colli…
Les Houches lectures on random quantum circuits and monitored quantum dynamics
Romain Vasseur
These lecture notes are based on lectures given by the author at the Les Houches 2025 summer school on "Exact Solvability and Quantum Information". The central theme of these notes…
Universal Statistics of Measurement-Induced Entanglement in Tomonaga-Luttinger liquids
Kabir Khanna, Romain Vasseur
We study the statistics of measurement-induced entanglement (MIE) after partial measurement on a class of one-dimensional quantum critical states described by Tomonaga-Luttinger li…
Learning measurement-induced phase transitions using attention
Hyejin Kim, Abhishek Kumar, Yiqing Zhou +3
Measurement-induced phase transitions (MIPTs) epitomize new intellectual pursuits inspired by the advent of quantum hardware and the emergence of discrete and programmable circuit…
Measurement-Induced Entanglement in Conformal Field Theory
Kabir Khanna, Romain Vasseur
Local measurements can radically reshape patterns of many-body entanglement, especially in long-range entangled quantum-critical states. Yet, analytical results addressing the effe…
Flow to Nishimori universality in weakly monitored quantum circuits with qubit loss
Malte Pütz, Romain Vasseur, Andreas W. W. Ludwig +2
In circuit-based quantum state preparation, qubit loss and coherent errors are circuit imperfections that imperil the formation of long-range entanglement beyond a certain threshol…
Tensor Cross Interpolation of Purities in Quantum Many-Body Systems
Dmytro Kolisnyk, Raimel A. Medina, Romain Vasseur +1
A defining feature of quantum many-body systems is the exponential scaling of the Hilbert space with the number of degrees of freedom. This exponential complexity naïvely renders a…
Decoherence-induced self-dual criticality in topological states of matter
Qingyuan Wang, Romain Vasseur, Simon Trebst +2
Quantum measurements performed on a subsystem of a quantum many-body state can generate entanglement for its remaining constituents. The whole system including the measurement reco…
Random Quantum Circuits with Time-Reversal Symmetry
Kabir Khanna, Abhishek Kumar, Romain Vasseur +1
Time-reversal (TR) symmetry is crucial for understanding a wide range of physical phenomena, and plays a key role in constraining fundamental particle interactions and in classifyi…
Operator scaling dimensions and multifractality at measurement-induced transitions
Aidan Zabalo, Michael J. Gullans, Justin H. Wilson +5
Repeated local measurements of quantum many body systems can induce a phase transition in their entanglement structure. These measurement-induced phase transitions (MIPTs) have bee…
