The ebbs and flows of quantum learning and sensing
Matias Karjula, Teemu Ojanen, Tapio Ala-Nissila +1
What is the relation between subsystem quantum complexity and the emergence of computationally useful structure? We address this by studying a family of minimally tunable postvaria…
Optimal quantum reservoir learning in proximity to universality
Moein N. Ivaki, Matias Karjula, Tapio Ala-Nissila
The study of the boundary between classically simulable and computationally complex quantum dynamics is fundamental to understanding which physical resources may enable enhanced in…
Dynamical learning and quantum memory with non-Hermitian many-body systems
Moein N. Ivaki, Austin J. Szuminsky, Achilleas Lazarides +3
Non-Hermitian (NH) systems provide a fertile platform for quantum technologies, owing in part to their distinct dynamical phases. These systems can be characterized by the preserva…
Noise resilience in adaptive and symmetric monitored quantum circuits
Moein N. Ivaki, Teemu Ojanen, Ali G. Moghaddam
Monitored quantum circuits offer great perspectives for exploring the interplay of quantum information and complex quantum dynamics. These systems could realize the extensively stu…
Quantum reservoir computing on random regular graphs
Moein N. Ivaki, Achilleas Lazarides, Tapio Ala-Nissila
Quantum reservoir computing (QRC) is a low-complexity learning paradigm that combines the inherent dynamics of input-driven many-body quantum systems with classical learning techni…
Postselection-free approach to monitored quantum dynamics and entanglement phase transitions
Kim Pöyhönen, Ali G. Moghaddam, Moein N. Ivaki +1
Measurement-induced entanglement phase transitions in monitored quantum circuits have stimulated activity in a diverse research community. However, the study of measurement-induced…
Quantum Hall effect and Landau levels without spatial long-range correlations
Isac Sahlberg, Moein N. Ivaki, Kim Pöyhönen +1
The spectrum of charged particles in translation-invariant systems in a magnetic field is characterized by the Landau levels, which play a fundamental role in the thermodynamic and…
Quantum walks on random lattices: Diffusion, localization and the absence of parametric quantum speed-up
Rostislav Duda, Moein N. Ivaki, Isac Sahlberg +2
Discrete-time quantum walks, quantum generalizations of classical random walks, provide a framework for quantum information processing, quantum algorithms and quantum simulation of…
Topological Random Fractals
Moein N. Ivaki, Isac Sahlberg, Kim Pöyhönen +1
We introduce the notion of topological electronic states on random lattices in non-integer dimensions. By considering a class model on critical percolation clusters embedded in…
Criticality in amorphous topological matter -- beyond the universal scaling paradigm
Moein N. Ivaki, Isac Sahlberg, Teemu Ojanen
We establish the theory of critical transport in amorphous Chern insulators and show that it lies beyond the current paradigm of topological criticality epitomized by the quantum H…
