Di Dato, Federico Lupo (author)Fluidic interfaces use liquids to sense, compute, and output a dynamic appearance or behavior in response to mechanical deformation inputs.<br/>Integrating logic and user-actuated control mechanisms in the interfaces can, in the future, enable to achieve more complex dynamic behaviors for designing interactive artifacts that are entirely analog...master thesis 2023

Guurink, Koen (author)Building a distributed fluidic actuation system is a challenge due to every actuator needs its own control valve. Due to this, an n by an array of actuators needs n 2 number of valves. A logic network of valves provides a solution by reducing the number of valves needed to operate such distributed fluidic actuation system. These compliant...master thesis 2023

Xue, X. (author), 't Hart, P.A. (author), Charbon-Iwasaki-Charbon, E. (author), Sebastiano, F. (author), Vladimirescu, A. (author)As big strides were being made in many science fields in the 1970s and 80s, faster computation for solving problems in molecular biology, semiconductor technology, aeronautics, particle physics, etc., was at the forefront of research. Parallel and super-computers were introduced, which enabled problems of a higher level of complexity to be...journal article 2023

Mahmoud, A.N.N. (author)CMOS downscaling has provided the means to efficiently process the huge raw data resulted from the information technology revolution. However, this becomes more difficult because of leakage, reliability, and cost walls. To keep the pace with the exploding market needs at affordable cost, novel alternative technologies are under investigation;...doctoral thesis 2022

(author), Zhang, X. (author)Magnonics addresses the physical properties of spin waves and utilizes them for data processing. Scalability down to atomic dimensions, operation in the GHz-to-THz frequency range, utilization of nonlinear and nonreciprocal phenomena, and compatibility with CMOS are just a few of many advantages offered by magnons. Although magnonics is still...journal article 2022

Vuillot, C. (author), Breuckmann, Nikolas P. (author)We introduce quantum pin codes: a class of quantum CSS codes. Quantum pin codes are a generalization of quantum color codes and Reed-Muller codes and share a lot of their structure and properties. Pin codes have gauge operators, an unfolding procedure and their stabilizers form so-called $\ell $ -orthogonal spaces meaning that the joint...journal article 2022

Pashaeifar, M. (author), de Vreede, L.C.N. (author), Alavi, S.M. (author)This letter presents a novel load-modulation-based 3rd-order intermodulation distortion (IMD3) cancellation technique for class-B CMOS power amplifiers (PAs). In a class-B PA, the IMD3 generated by the 3rd-order transconductance ( $g_{m3}$ ) and the gain compression have opposite signs, and thus, they can cancel each other at specific bias...journal article 2022

Theuwissen, A.J.P.A.M. (author)This article focuses on the angular dependency of the light sensitivity of a commercially available CMOS camera with a global shutter (storage node (SG) in the charge domain) and shared pixel architecture. The angular dependency is characterized as a function of both the wavelength and the angle of incidence of the incoming light. The...journal article 2022

(author)Fully digital transmitters (DTXs) have the potential of replacing analog-intensive transmitter (TX) line-ups in future massive multiple-input and multiple-output (mMIMO) systems since they hold the promise of higher system integration level and energy efficiency. DTX operation so far has been limited to low RF output powers. This article...journal article 2022

Sharma, Salil (author), van Lint, J.W.C. (author), Tavasszy, Lorant (author), Snelder, M. (author)This paper studies and compares the gap selection process of multiple vehicle classes (passenger cars, delivery vans, and trucks) within their discretionary lane changing activities. Given a trajectory or a sequence of gap selection decisions, we aim to predict whether a vehicle will change or keep a lane. For this purpose, we use a large...journal article 2022

Steinberg, M.A. (author), Feld, S. (author), Almudever, Carmen G. (author), Marthaler, Michael (author), Reiner, Jan Michael (author)The qubit-mapping problem aims to assign and route qubits of a quantum circuit onto an noisy intermediate-scale 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

Mahmoud, A.N.N. (author), Vanderveken, Frederic (author), Ciubotaru, Florin (author), Adelmann, Christoph (author), Hamdioui, S. (author), Cotofana, S.D. (author)By their very nature Spin Waves (SWs) enable the realization of energy efficient circuits, as they propagate and interfere within waveguides without consuming noticeable energy. However, SW computing can be even more energy efficient by taking advantage of the approximate computing paradigm as many applications, e.g., multimedia and social...journal article 2022

Gong, J. (author), Chen, Y. (author), Charbon-Iwasaki-Charbon, E. (author), Sebastiano, F. (author), Babaie, M. (author)This article presents a 4-to-5GHz LC oscillator operating at 4.2K for quantum computing applications. The phase noise (PN) specification of the oscillator is derived based on the control fidelity for a single-qubit operation. To reveal the substantial gap between the theoretical predictions and measurement results at cryogenic temperatures, a...journal article 2022

Overwater, R.W.J. (author), Babaie, M. (author), Sebastiano, F. (author)Quantum error correction (QEC) is required in quantum computers to mitigate the effect of errors on physical qubits. When adopting a QEC scheme based on surface codes, error decoding is the most computationally expensive task in the classical electronic back-end. Decoders employing neural networks (NN) are well-suited for this task but their...journal article 2022

Mahmoud, A.N.N. (author), Vanderveken, Frederic (author), Adelmann, Christoph (author), Ciubotaru, Florin (author), Hamdioui, S. (author), Cotofana, S.D. (author)By their very nature, spin waves (SWs) with different frequencies can propagate through the same waveguide, while mostly interfering with their own species. Therefore, more SW encoded data sets can coexist, propagate, and interact in parallel, which opens the road toward hardware replication-free parallel data processing. In this article, we...journal article 2021

(author)Having multi-output logic gates saves much energy because the same structure can be used to feed multiple inputs of next stage gates simultaneously. This paper proposes novel triangle shape fanout of 2 spin wave Majority and XOR gates; the Majority gate is achieved by phase detection, whereas the XOR gate is achieved by threshold detection. The...conference paper 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
