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…
Thermodynamics of Coherence-Selective Quantum Reset Protocols
Jishad Kumar, Achilleas Lazarides, Tapio Ala-Nissila
We develop an exact theory of coherence-selective stroboscopic resetting for quadratic open quantum systems within the single-particle density-matrix formalism. We focus on the sur…
Coherence-Controlled Quantum Zeno Dynamics from Exact Reset Maps
Jishad Kumar, Achilleas Lazarides, Tapio Ala-Nissila
We develop an exact framework for quantum Zeno and anti-Zeno dynamics in a broad class of open systems, whose microscopic Hamiltonians are quadratic in bosonic or fermionic operato…
Interaction-Enabled Hartree Fixed Points in Fermionic Resetting Dynamics
Jishad Kumar, Achilleas Lazarides, Tapio Ala-Nissila
In resetting dynamics, a system is repeatedly coupled to and decoupled from ancillary degrees of freedom that are reinitialized between interactions. This provides a versatile rout…
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…
