Apak, Boran (author)The goal of this thesis is expanding quantum algorithm datasets to enhance our capability to benchmark quantum systems and to open up possibilities for using machine learning techniques in quantum circuit mapping. Both of these areas are currently hindered by the lack of a wide range of useful quantum algorithms. To solve this problem, KetGPT is...master thesis 2023

Bandic, M. (author), Almudever, Carmen G. (author), Feld, S. (author)To execute quantum circuits on a quantum processor, they must be modified to meet the physical constraints of the quantum device. This process, called quantum circuit mapping, results in a gate/circuit depth overhead that depends on both the circuit properties and the hardware constraints, being the limited qubit connectivity a crucial...journal article 2023

Steinberg, M.A. (author), Feld, S. (author), Almudever, Carmen G. (author), Marthaler, Michael (author), Reiner, Jan Michael (author)The qubitmapping problem aims to assign and route qubits of a quantum circuit onto an noisy intermediatescale quantum (NISQ) device in an optimized fashion, with respect to some cost function. Finding an optimal solution to this problem is known to scale exponentially in computational complexity; as such, it is imperative to investigate...journal article 2022

Ma, L. (author)Complex systems are made up of many interconnected components. The interactions between components further produce emerging complex collective behaviors. In most cases, a complex system can be represented as a network in which the nodes represent the elements and the connected links illustrate the interactions. The spreading process is one of...doctoral thesis 2021

Lao, L. (author), van Someren, J. (author), Ashraf, I. (author), Almudever, Carmen G. (author)Quantum algorithms need to be compiled to respect the constraints imposed by quantum processors, which is known as the mapping problem. The mapping procedure will result in an increase of the number of gates and of the circuit latency, decreasing the algorithm's success rate. It is crucial to minimize mapping overhead, especially for noisy...journal article 2021

Ma, L. (author), Sanders, Jaron (author)We study a classical model for the accumulation of errors in multiqubit quantum computations. By modeling the error process in a quantum computation using two coupled Markov chains, we are able to capture a weak form of timedependency between errors in the past and future. By subsequently using techniques from the field of discrete...conference paper 2021

Bandic, M. (author), Zarein, Hossein (author), Alarcon, Eduard (author), Almudever, Carmen G. (author)Quantum algorithms can be expressed as quantum circuits when the circuit model of computation is adopted.
