主题范围

The past few years have witnessed the emergence of a new paradigm studying idealized models for many-body physics out of equilibrium, consisting of local quantum circuits and quantum cellular automata (QCA).

A compelling motivation for the study of these models came from the advent of so-called Noisy-Intermediate-Scale-Quantum devices, implementing early prototypes for digital quantum computers. When viewed as physical systems operating close to their native hardware, these devices can be conceptualized as sets of qubits evolving according to discrete sequences of few-body unitary processes, possibly interspersed with local projective measurements and feedback. These ingredients give rise to dynamics which may be completely different from the local-Hamiltonian evolution traditionally studied in condensed matter physics, allowing for novel types of universal behavior and collective effects.

Quantum circuits and QCA have been used as minimal theoretical models to deepen our understanding of these new effects. In addition, despite being extreme idealizations for the many-body dynamics of real systems, their simplifying minimal structure also provides an analytic handle on topical but hard questions in quantum chaos, thermalization, and quantum information scrambling. Simplifications are often made possible by statistical mappings leveraging the discrete space-time structure or the presence of randomness and disorder, establishing several connections to topics in statistical mechanics and mathematical physics.

The aim of this special issue is to collect research at the cutting edge of this emerging field. The specific topics include:

• Dual unitary quantum circuits: dynamics and classifications
• Random quantum circuits (short- and long-range models for chaotic dynamics)
• Measurement-induced entanglement phase transition in random and dual unitary quantum circuits
• Integrable and non-integrable quantum cellular automata
• Projected Ensemble and deep thermalization
• Complexity transitions in shallow vs deep quantum circuits

This issue is dedicated to the memory of Marko Medenjak
