Uniqueness and nonuniqueness in the disjoint data inverse problem: a sharp spectral threshold
Lauri Ylinen
We study the inverse problem of determining a connected, closed Riemannian manifold of dimension at least two from wave observations. The sources are supported in an open set ,…
Gate Freezing Method for Gradient-Free Variational Quantum Algorithms in Circuit Optimization
Joona Pankkonen, Lauri Ylinen, Matti Raasakka +2
Parameterized quantum circuits (PQCs) are pivotal components of variational quantum algorithms (VQAs), which represent a promising pathway to quantum advantage in noisy intermediat…
Improving Variational Quantum Circuit Optimization via Hybrid Algorithms and Random Axis Initialization
Joona V. Pankkonen, Lauri Ylinen, Matti Raasakka +1
Variational quantum circuits (VQCs) are an essential tool in applying noisy intermediate-scale quantum computers to practical problems. VQCs are used as a central component in many…
Noisy Quantum Simulation: Performance and Resource Considerations for the Tavis-Cummings and Heisenberg Models
Alisa Haukisalmi, Daniel Paz Ramos, Matti Raasakka +3
Fault-tolerant quantum computers promise the simulation of complex quantum systems beyond the reach of classical computation. In contrast, current noisy intermediate-scale quantum…
Quantum computing algorithms for inverse problems on graphs and an NP-complete inverse problem
Joonas Ilmavirta, Matti Lassas, Jinpeng Lu +2
We consider an inverse problem for a finite graph where we are given a subset of vertices and the distances of all vertices …
Disjoint data inverse problem on manifolds with quantum chaos bounds
Matti Lassas, Medet Nursultanov, Lauri Oksanen +1
We consider the inverse problem to determine a smooth compact Riemannian manifold from a restriction of the source-to-solution operator, , for the wave e…
Analysis of a dynamical system modeling lasers and applications for optical neural networks
Lauri Ylinen, Tuomo von Lerber, Franko Küppers +1
An analytical study of dynamical properties of a semiconductor laser with optical injection of arbitrary polarization is presented. It is shown that if the injected field is suffic…
Inverse problems for heat equation and space-time fractional diffusion equation with one measurement
Tapio Helin, Matti Lassas, Lauri Ylinen +1
Given a connected compact Riemannian manifold without boundary, , we consider a space--time fractional diffusion equation with an interior source that is suppo…
