Logical structures underlying quantum computing Vrije Universiteit Brussel
In this work we advance a generalization of quantum computational logics capable of dealing with some important examples of quantum algorithms. We outline an algebraic axiomatization of these structures.
On two subgroups of U(n), useful for quantum computing Ghent University
On two subgroups of U(n), important for quantum computing Ghent University
ZU(n) and XU(n) are subgroups of the unitary group U(n): the group XU(n) consists of all n X n unitary matrices with all 2n line sums (i.e. all n row sums and all n column sums) equal to 1 and the group ZU(n) consists of all n X n unitary diagonal matrices with first entry equal to 1.
Characterization and Modelling of the Quantum-classical Interface for Scalable Superconducting Quantum Computing KU Leuven
Quantum Computing holds promise to solve complex computational problems which are intractable by classical calculators. To date, the most advanced solid-state implementation of a Qubit (or a system of Qubits) is realized with Superconducting circuits arranged in the so-called circuit-Quantum-Electro-Dynamics (cQED) architecture. Although this technology has proven to be mature for the implementation of basic Quantum Algorithms, it presents ...
Transparallel mind: Classical computing with quantum power KU Leuven
Inspired by the extraordinary computing power promised by quantum computers, the quantum mind hypothesis postulated that quantum mechanical phenomena are the source of neuronal synchronization, which, in turn, might underlie consciousness. Here, I present an alternative inspired by a classical computing method with quantum power. This method relies on special distributed representations called hyperstrings. Hyperstrings are superpositions of up ...
Exploring High-Symmetry Lanthanide-Functionalized Polyoxopalladates as Building Blocks for Quantum Computing KU Leuven
The structural, electronic and magnetochemical properties of the star-shaped polyoxopalladate [Pd15O10(SeO3)10]10− (POPd) and its lanthanide functionalized derivatives have been investigated on the basis of density functional theory followed by a ligand field analysis using the Radial Effective Charge (REC) model. Our study predicts that heteroPOPd is a robust cryptand that enforces D5h symmetry around the encapsulated Ln3+ centers. This rigid ...
New insights on the excess 1/f noise at cryogenic temperatures in 28 nm CMOS and Ge MOSFETs for quantum computing applications Interuniversity Microelectronics Centre
Cryogenic temperature DC-IV measurements and compact modeling of n-channel bulk FinFETs with 3–4 nm wide fins and 20 nm gate length for quantum computing applications Vrije Universiteit Brussel
CMOS circuits for Quantum Computing applications require FETs operating at cryogenic temperatures. In this work, we aim to present one of the first insights on the ability of the industry standard compact model BSIMCMG in capturing low temperature device physics. We have performed wafer-level DC-IV measurements on multi-fin n- channel bulk FinFETs with 3–4 nm wide fins and down to 20 nm designed gate length across a range of temperatures ...
