Krol, A.M. (author), Sarkar, A. (author), Ashraf, I. (author), Al-Ars, Z. (author), Bertels, K.L.M. (author)Unitary decomposition is a widely used method to map quantum algorithms to an arbitrary set of quantum gates. Efficient implementation of this decomposition allows for the translation of bigger unitary gates into elementary quantum operations, which is key to executing these algorithms on existing quantum computers.

Yu, J. (author), Nane, R. (author), Ashraf, I. (author), Taouil, M. (author), Hamdioui, S. (author), Corporaal, Henk (author), Bertels, K.L.M. (author)Memristor-based Computation-in-Memory (CIM) is one of the emerging architectures for next-generation Big Data problems. Its design requires a radically new synthesis flow as the memristor is a passive device that uses resistances to encode its logic values. This article proposes a synthesis flow for mapping parallel applications on memristor...journal article 2020

Moueddene, A.A. (author), Khammassi, Nader (author), Bertels, K.L.M. (author), Almudever, Carmen G. (author)The implementation and practicality of quantum algorithms hinge largely on the quality of operations within a quantum processor. Therefore, including realistic error models in quantum computing simulation platforms is crucial for testing these algorithms. Existing classical simulation techniques of quantum information processing devices...journal article 2020

Ahmed, N. (author), Qiu, T.D. (author), Bertels, K.L.M. (author), Al-Ars, Z. (author)BACKGROUND: In Overlap-Layout-Consensus (OLC) based de novo assembly, all reads must be compared with every other read to find overlaps. This makes the process rather slow and limits the practicality of using de novo assembly methods at a large scale in the field. Darwin is a fast and accurate read overlapper that can be used for de novo...journal article 2020

Ahmed, N. (author), Bertels, K.L.M. (author), Al-Ars, Z. (author)The seeding heuristic is widely used in many DNA analysis applications to speed up the analysis time. In many applications, seeding takes a substantial amount of the total execution time. In this paper, we present an efficient GPU implementation for computing maximal exact matching (MEM) seeds in long DNA reads. We applied various...conference paper 2020

(author)The large-scale execution of quantum algorithms requires basic quantum operations to be implemented fault-tolerantly. The most popular technique for accomplishing this, using the devices that can be realized in the near term, uses stabilizer codes which can be embedded in a planar layout. The set of fault-tolerant operations which can be...journal article 2019

(author)Quantum error correction (QEC) and fault-tolerant (FT) mechanisms are essential for reliable quantum computing. However, QEC considerably increases the computation size up to four orders of magnitude. Moreover, FT implementation has specific requirements on qubit layouts, causing both resource and time overhead. Reducing spatial-temporal costs...journal article 2019
