F-Divergences and Cost Function Locality in Generative Modelling with Quantum Circuits
Entropy, 2021 Generative modelling is an important unsupervised task in machine learning. In this work, we study a hybrid quantum-classical approach to this task, based on the use of a quantum circuit born machine. In particular, we consider training a quantum circuit

SU(2) hadrons on a quantum computer via a variational approach
Nature Communications, 2021 Quantum simulations of lattice gauge theories are in principle scalable, but their extension to dynamically coupled matter has proven difficult. In this work, the authors use a variational quantum eigensolver to simulate a non-Abelian LGT including the ...

17th Congress of the International Commission for Optics: Optics for Science and New Technology, 1996 Quantum theory is vital for the next generation data processing devices. As computers become faster they must become smaller because of the finiteness of the speed of light. The history of computer technology has involved a sequence of changes from one type of physical realisation to another - from gears to relays to valves to transistors to integrated

Quantum analogue computing [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2010 We briefly review what a quantum computer is, what it promises to do for us and why it is so hard to build one. Among the first applications anticipated to bear fruit is the quantum simulation of quantum systems. While most quantum computation is an extension of classical digital computation, quantum simulation differs fundamentally in how the data are

Simultaneous Execution of Quantum Circuits on Current and Near-Future NISQ Systems
IEEE Transactions on Quantum Engineering, 2022 In the noisy intermediate-scale quantum (NISQ) era, the idea of quantum multiprogramming, running multiple quantum circuits (QCs) simultaneously on the same hardware, helps to improve the throughput of quantum computation.

Journal of Engineering Science, 2021 The quantum computer, is a "supercomputer" that relies on the phenomena of quantum mechanics to perform operations on data. Object of suppositions, sometimes farfetched, quantum mechanics gave birth to the quantum computer, a machine capable of processing data tens of millions of times faster than a conventional computer. A quantum computer doesn't use
