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…
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…
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…
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…
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…
