A Boundary Modeling Scheme to Bridge the Computational Gap Between Classic Electrodynamics and Quantum Physics KU Leuven
IMPaCT: Implementing Multi-Party Computation Technology. KU Leuven
The goal of IMPaCT is to turn Multi-Party Computation (MPC) from a stage in which we are beginning to obtain practical feasibility results, to a stage in which we have fully practical systems. It has long been acknowledged that MPC has the potential to provide a transformative change in the way security solutions are enabled. As it presently stands this is currently only possible in limited applications; deployments in restricted scenarios ...
Making a quantum computer talk chemistry: conceptual open quantum systems as insightful tools for quantum computing approaches to quantum chemistry Ghent University
Quantum computers have the potential to revolutionize quantum chemistry because they can, in principle, compute accurate electronic structure models very efficiently. At the moment, however, we are technologically limited to so-called ‘noisy intermediate-scaling quantum' (NISQ) devices, which suffer from calculation errors (noise) because they are very sensitive to their environment. Despite these noise issues, accurate molecular energies can ...

Quantum chaos and quantum complexity in quantum resonant systems. Vrije Universiteit Brussel
context of quantum resonant systems. Quantum resonant systems
arise upon quantizing classical resonant systems. The latter provide
controlled approximations to the dynamics of interesting classes of
weakly nonlinear systems, including weakly interacting Bose-Einstein
condensates in harmonic traps and weakly interacting fields in antide Sitter (AdS) ...
Hardware efficient microarchitecture and quantum error correction codes for large scale quantum processors KU Leuven
With the recent demonstration of quantum supremacy, quantum computing is entering the era of Noisy Intermediate Scale Quantum computing (NISQ), where dozens to several hundreds of artificial quantum objects interact in such a way as to perform computationally intractable yet trivial tasks such as simulating their own behavior [1]. Yet, even the most optimistic estimates assume that many millions of qubits will be required for properly ...
Quantum complexity, quantum entanglement and the emergence of spacetime Vrije Universiteit Brussel
structured non-local quantum entanglement may underpin the
emergence of spacetime from the underlying degrees of freedom,
and the recovery of information from black holes. To realize this
picture in the model that describes M-theory, the master theory in 11
dimensions from which all string theories descend, we must learn
how to describe and ...
Development of a quantum dot single photon source on Silicon for the next generation integrated quantum circuits Ghent University
Quantum technologies have received much interest in the last years thanks to the promise of extreme computational power and secure data transmission. Single photons are important elements for these technologies, being suitable candidates both for quantum computing and communication. This triggered the research community to develop an ideal single photon source (SPS). Devices based on InAs quantum dots (QDs) grown on GaAs substrates are the ...
Entanglement and tensor network states for quantum field theories. Ghent University
Schrödinger probably had a cat, but he surely coined the concept of entanglement as the general characterization of quantum correlations. In his words (1935): "the best possible knowledge of a whole does not necessarily include the best possible knowledge of all its parts." The theory of entanglement has then been mainly developed in quantum information theory, where it serves as a universal resource for the different tasks (e.g. quantum ...
