Quantum algorithm for the lattice Boltzmann method with applications on real quantum devices
Antonio Bastida-Zamora, Ljubomir Budinski, Oskari Kerppo +8
We introduce a novel quantum algorithm for the lattice Boltzmann method (LBM) based on the one-step simplified LBM. The structure of the algorithm allows for more flexibility in mo…
Minimizing entanglement entropy for enhanced quantum state preparation
Oskari Kerppo, William Steadman, Ossi Niemimäki +1
Quantum state preparation is an important subroutine in many quantum algorithms. The goal is to encode classical information directly to the quantum state so that it is possible to…
Towards reliable quantum software, algorithm and use-case development: Multidisciplinary analysis from the perspective of Finnish industries
Matti Silveri, Tommi Mikkonen, Kimmo Halunen +6
Quantum computing is a disruptive technology with the potential to transform various fields. It has predicted abilities to solve complex computational problems beyond the reach of…
Random Exclusion Codes: Quantum Advantages of Single-Shot Communication
Joonwoo Bae, Kieran Flatt, Teiko Heinosaari +4
Useful applications of quantum information technologies can be found by identifying tasks in which quantum resources outperform their classical counterparts. In this work, we intro…
Gate teleportation-assisted routing for quantum algorithms
Aravind Plathanam Babu, Oskari Kerppo, Andrés Muñoz Moller +2
The limited qubit connectivity of quantum processors poses a significant challenge in deploying practical algorithms and logical gates, necessitating efficient qubit mapping and ro…
Maximal Elements of Quantum Communication
Teiko Heinosaari, Oskari Kerppo
A prepare-and-measure scenario is naturally described by a communication matrix that collects all conditional outcome probabilities of the scenario into a row-stochastic matrix. Th…
Simple Information Processing Tasks with Unbounded Quantum Advantage
Teiko Heinosaari, Oskari Kerppo, Leevi Leppäjärvi +1
Communication scenarios between two parties can be implemented by first encoding messages into some states of a physical system which acts as the physical medium of the communicati…
Partial ignorance communication tasks in quantum theory
Oskari Kerppo
We introduce a generalization of communication of partial ignorance where both parties of a prepare-and-measure setup receive inputs from a third party before a success metric is m…
Experimentally accessible non-separability criteria for multipartite entanglement structure detection
Guillermo García-Pérez, Oskari Kerppo, Matteo A. C. Rossi +1
The description of the complex separability structure of quantum states in terms of partially ordered sets has been recently put forward. In this work, we address the question of h…
Reheating in the kination epoch via multi-channel decay of gravitationally created massive scalars
Juho Lankinen, Oskari Kerppo, Iiro Vilja
We provide a detailed study of reheating in the kination regime in a scenario where the particle content is produced by gravitational production of massive scalars decaying into ma…
Communication tasks in operational theories
Teiko Heinosaari, Oskari Kerppo, Leevi Leppäjärvi
We investigate the question which communication tasks can be accomplished within a given operational theory. The concrete task is to find out which communication matrices have a pr…
Reheating via gravitational particle production in kination epoch
Juho Lankinen, Oskari Kerppo, Iiro Vilja
We provide a detailed study of reheating in the kination regime where particle content is created by gravitational production of massive scalars mutually interacting with a massles…
Communication of partial ignorance with qubits
Teiko Heinosaari, Oskari Kerppo
We introduce a class of communication tests where the task is to communicate partial ignorance by means of a physical system. We present a full characterization of the implementati…
Entanglement Protection via Periodic Environment Resetting in Continuous Time Quantum Dynamical Processes
Thomas Bullock, Francesco Cosco, Marwan Haddara +8
The temporal evolution of entanglement between a noisy system and an ancillary system is analyzed in the context of continuous time open quantum system dynamics. Focusing on a coup…
Antidistinguishability of Pure Quantum States
Teiko Heinosaari, Oskari Kerppo
The Pusey-Barrett-Rudolph theorem has recently provoked a lot of discussion regarding the reality of the quantum state. In this article we focus on a property called antidistinguis…
