Information scrambling in quantum circuits

Xiao Mi et al.

Summary: By measuring the time-dependent evolution and fluctuation of out-of-time-order correlators on a 53-qubit quantum processor, this experiment investigates the dynamics of quantum scrambling. It is shown that operator entanglement in idealized circuits requires exponentially scaled computational resources to simulate, while operator spreading can be captured by an efficient classical model. These results pave the way for studying complex physical observables with near-term quantum processors.

Controlling quantum many-body dynamics in driven Rydberg atom arrays

D. Bluvstein et al.

Summary: The study demonstrates that coherent revivals associated with quantum many-body scars can be stabilized by periodic driving, generating a robust subharmonic response akin to discrete timecrystalline order. This finding provides new ways to control complex dynamics in many-body systems and may have potential applications in quantum information science.

A dynamical mechanism for the Page curve from quantum chaos

Hong Liu et al.

Summary: This study demonstrates that the Page curve can be explained by a simple dynamical input in the evolution of black holes, based on a recently proposed signature of quantum chaos, without relying on typicality. The operator gas approach is introduced to understand the evolution of the black hole's microstate. Void formation processes, where operators in the gas can jump outside the black hole, play a crucial role in leading to the Page curve.

Transverse Spin Dynamics in the Anisotropic Heisenberg Model Realized with Ultracold Atoms

Paul Niklas Jepsen et al.

Summary: The study utilizes ultracold atoms to simulate the dynamics of 1D Heisenberg spin chains, observing fast spin decay controlled by anisotropy and dephasing caused by the effective magnetic field from superexchange. The research also reveals new dephasing mechanisms, including inhomogeneity of the effective field, reduction of field at chain edges, and fluctuations due to mobile holes. These mechanisms have not been previously observed with ultracold atoms, providing insights into the Hubbard model.

Quasisymmetry Groups and Many-Body Scar Dynamics

Jie Ren et al.

Summary: In quantum systems, a subspace spanned by degenerate eigenvectors of the Hamiltonian may have higher symmetries than those of the Hamiltonian itself. Coupling an external field to certain generators of the quasisymmetry group can lift the degeneracy and result in exactly periodic dynamics within the degenerate subspace.

Programmable quantum simulations of spin systems with trapped ions

C. Monroe et al.

Summary: Laser-cooled and trapped atomic ions provide an ideal platform for simulating interacting quantum spin models. By using optical fields to modulate the ions' Coulomb interaction, long-range and tunable spin-spin interactions can be produced. This quantum simulator allows for the study of complex equilibrium states and dynamical processes in many-body interacting quantum systems.

Dynamical Freezing and Scar Points in Strongly Driven Floquet Matter: Resonance vs Emergent Conservation Laws

Asmi Haldar et al.

Summary: In this study, a clean quantum system subject to strong periodic driving is investigated, revealing the presence of freezing points in the space of drive parameters and the emergence of an almost exact, local conserved quantity. The phenomenon, which affects the entire Floquet spectrum, is shown to be robust across a variety of Hamiltonians, including those with two-body Heisenberg interactions. Resonance phenomena where the conservation breaks down and unbounded heating occurs are captured through a real-time perturbation theory, providing insights into the failure of the Magnus expansion in the low-frequency regime.

Quantum many-body scars and weak breaking of ergodicity

Maksym Serbyn et al.

Summary: Thermalization is the inevitable fate of many complex quantum systems, but recent discoveries have shown the existence of a new type of behavior called quantum many-body scarring, where the system rapidly relaxes for most initial conditions, yet certain initial states display non-ergodic dynamics. This phenomenon, similar to scars observed in single-particles in specific potentials, has potential applications in quantum technology.

Quantum Scars from Zero Modes in an Abelian Lattice Gauge Theory on Ladders

Debasish Banerjee et al.

Summary: This study explores the spectrum of a U(1) quantum link model using S = 1/2 spins as gauge fields and demonstrates a novel mechanism for generating quantum many-body scars in a constrained Hilbert space. The dynamics of many-body systems with local constraints has drawn significant attention due to the discovery of nonergodic behavior in quantum simulators based on Rydberg atoms. Lattice gauge theories serve as natural examples of constrained systems, with physical states being required to be gauge invariant.

Group theoretic approach to many-body scar states in fermionic lattice models

K. Pakrouski et al.

Summary: The research shows that three highly symmetric families of states are many-body scars for certain forms of fermionic Hamiltonians, with one of them being the well-known eta-pairing states. These states, besides possessing typical scar properties, are also insensitive to electromagnetic noise and advantageous for quantum information storage and processing. Additionally, various common coupling terms and the Hamiltonians containing them support these states as scars without requiring fine-tuning.

Hilbert space fragmentation and exact scars of generalized Fredkin spin chains

Christopher M. Langlett et al.

Summary: This work introduces a family of spin-1/2 many-body Hamiltonians based on the Fredkin spin chain, featuring a fragmented Hilbert space and quantum many-body scars. Exact middle spectrum eigenstates are constructed to demonstrate logarithmic or area-law entanglement entropy within each fractured subsector. The interplay between fragmentation and scarring results in rich tunable nonergodic dynamics.

Many-body scar state intrinsic to periodically driven system

Sho Sugiura et al.

Summary: The violation of the Floquet version of the eigenstate thermalization hypothesis is discussed with realistic Hamiltonians, rigorously proving the existence of many-body scar states in the Floquet eigenstates. The breakdown of the Floquet eigenstate thermalization hypothesis is demonstrated for the first time through explicit expressions of the wave functions, providing insight into the underlying physical mechanism. Floquet-scar states can be systematically engineered in various driven Hamiltonians based on this mechanism, and can be checked through time evolution of observables in a chain of Rydberg atoms.
