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) ...

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 ...
Quantum information for quantum fiel Ghent University
Recently, borrowing techniques and concepts from quantum information theory, two powerfull methods (PEPS and MERA) appeared, that allow a new quantitative and qualitative understanding of discrete quantum systems. The overall goal of our research project is to contribute to the exploration of these methods in the context of quantum field theories. This could provide a new framework for the study of the strongly coupled regime in dynamical ...
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 ...
Investigating signatures of quantum gravity via classical and quantum corrections in black holes KU Leuven
One outstanding challenge in fundamental physics pertains to finding a consistent theory of quantum gravity - the intersection of gravitational physics and quantum physics. Black holes are interesting models to understand the quantum structure of gravity. As technology has advanced and there have been more experimental probes for gravity, it is then time to provide additional theoretical predictions that may ultimately be observed. Of ...

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 ...
