Deep thermalization and Hilbert space ergodicity
Daniel K. Mark, Manuel Endres, Matteo Ippoliti +2
Recent advances in quantum simulation have enabled the discovery of novel forms of universality in quantum many-body dynamics. In this Review, we discuss deep thermalization and Hi…
Quantum resource localizability transitions in deep thermalization
Xiaozhou Feng, Chang Liu, Zihan Cheng +2
We investigate how quantum resource constraints affect deep thermalization, the emergence of universal local wavefunction distributions from partial measurements of a quantum many-…
Coherence-induced deep thermalization transition in random permutation quantum dynamics
Chang Liu, Matteo Ippoliti, Wen Wei Ho
We report a phase transition in the projected ensemble - the collection of post-measurement wavefunctions of a local subsystem obtained by measuring its complement. The transition…
Simulation of bilayer Hamiltonians based on monitored quantum trajectories
Yuan Xue, Zihan Cheng, Matteo Ippoliti
In the study of open quantum systems it is often useful to treat mixed states as pure states of a fictitious doubled system. In this work we explore the opposite approach: mapping…
Infinite temperature at zero energy
Matteo Ippoliti, David M. Long
We construct a family of static, geometrically local Hamiltonians that inherit eigenstate properties of periodically-driven (Floquet) systems. Our construction is a variation of th…
Hardness of observing strong-to-weak symmetry breaking
Xiaozhou Feng, Zihan Cheng, Matteo Ippoliti
Spontaneous symmetry breaking (SSB) is the cornerstone of our understanding of quantum phases of matter. Recent works have generalized this concept to the domain of mixed states in…
Pseudoentanglement from tensor networks
Zihan Cheng, Xiaozhou Feng, Matteo Ippoliti
Pseudoentangled states are defined by their ability to hide their entanglement structure: they are indistinguishable from random states to any observer with polynomial resources, y…
Deep thermalization under charge-conserving quantum dynamics
Rui-An Chang, Harshank Shrotriya, Wen Wei Ho +1
"Deep thermalization" describes the emergence of universal wavefunction distributions in quantum many-body dynamics, appearing on a local subsystem upon measurement of its environm…
Approximate inverse measurement channel for shallow shadows
Riccardo Cioli, Elisa Ercolessi, Matteo Ippoliti +2
Classical shadows are a versatile tool to probe many-body quantum systems, consisting of a combination of randomised measurements and classical post-processing computations. In a r…
Holographic Classical Shadow Tomography
Shuhan Zhang, Xiaozhou Feng, Matteo Ippoliti +1
We introduce "holographic shadows", a new class of randomized measurement schemes for classical shadow tomography that achieves the optimal scaling of sample complexity for learnin…
Charge and Spin Sharpening Transitions on Dynamical Quantum Trees
Xiaozhou Feng, Nadezhda Fishchenko, Sarang Gopalakrishnan +1
The dynamics of monitored systems can exhibit a measurement-induced phase transition (MIPT) between entangling and disentangling phases, tuned by the measurement rate. When the dyn…
Dynamics of Pseudoentanglement
Xiaozhou Feng, Matteo Ippoliti
The dynamics of quantum entanglement plays a central role in explaining the emergence of thermal equilibrium in isolated many-body systems. However, entanglement is notoriously har…
