Pulse-Engineered Controlled-V Gate and Its Applications on Superconducting Quantum Device

IEEE Transactions on Quantum Engineering, 2022
In this article, we demonstrate that, by employing the OpenPulse design kit for IBM superconducting quantum devices, the controlled-V gate (cv gate) can be implemented in about half the gate time to the controlled-X gate (cx or cnot gate) and ...

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

Applications of quantum computing for investigations of electronic transitions in phenylsulfonyl-carbazole TADF emitters

npj Computational Materials, 2021
A quantum chemistry study of the first singlet (S 1) and triplet (T 1) excited states of phenylsulfonyl-carbazole compounds, proposed as useful thermally activated delayed fluorescence (TADF) emitters for organic light emitting diode (OLED) applications,

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.

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 ...

Demonstration of long-range correlations via susceptibility measurements in a one-dimensional superconducting Josephson spin chain

npj Quantum Information, 2022
Spin chains have long been considered an effective medium for long-range interactions, entanglement generation, and quantum state transfer. In this work, we explore the properties of a spin chain implemented with superconducting flux circuits, designed ...

QUANTUM COMPUTING

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

Quantum neuromorphic computing [PDF]

Applied Physics Letters, 2020
Quantum neuromorphic computing physically implements neural networks in brain-inspired quantum hardware to speed up their computation. In this perspective article, we show that this emerging paradigm could make the best use of the existing and near future intermediate size quantum computers.

Microwaves in Quantum Computing [PDF]

IEEE Journal of Microwaves, 2021
Quantum information processing systems rely on a broad range of microwave technologies and have spurred development of microwave devices and methods in new operating regimes. Here we review the use of microwave signals and systems in quantum computing, with specific reference to three leading quantum computing platforms: trapped atomic ion qubits, spin

Quantum computation

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
