Microwave-to-optical quantum transduction of photons for quantum interconnects

Abstract The quantum transduction, or equivalently quantum frequency conversion, is vital for realizing, e.g., quantum networks and distributed quantum computing. The microwave-to-optical quantum transduction is of interest in the field of ...

Application-Motivated, Holistic Benchmarking of a Full Quantum Computing Stack

Quantum computing systems need to be benchmarked in terms of practical tasks they would be expected to do. Here, we propose 3 "application-motivated" circuit classes for benchmarking: deep (relevant for state preparation in the variational ...

Compact Ion-Trap Quantum Computing Demonstrator

Quantum information processing is steadily progressing from a purely academic discipline towards applications throughout science and industry.Transitioning from lab-based, proof-of-concept experiments to robust, integrated realizations of q...

Holographic Quantum Computing

We propose to use a single mesoscopic ensemble of trapped polar molecules for quantum computing. A "holographic quantum register" with hundreds of qubits is encoded in collective excitations with definite spatial phase variations. Each phas...

Quantum computing for smart grid applications

Abstract Computational complexities in modern power systems are reportedly increasing daily, and it is anticipated that traditional computers might be inadequate to provide the computation prerequisite in future complex power grids. In that...

A manufacturable platform for photonic quantum computing

Abstract Although holding great promise for low noise, ease of operation and networking 1 , useful photonic quantum computing has been precluded by the need for beyond-state-of-the-art components, manufactured by the millions 2–6 . Here we ...

Quantum Computing with an Electron Spin Ensemble

We propose to encode a register of quantum bits in different collective electron spin wave excitations in a solid medium. Coupling to spins is enabled by locating them in the vicinity of a superconducting transmission line cavity, and makin...

The state of quantum computing applications in health and medicine

Abstract Quantum computing hardware and software have made enormous strides over the last years1. Questions around quantum computing’s impact on research and society have changed from “if” to “when/how”. The 2020s have been described as the...

Quantum computing: A taxonomy, systematic review and future directions

Abstract Quantum computing (QC) is an emerging paradigm with the potential to offer significant computational advantage over conventional classical computing by exploiting quantum‐mechanical principles such as entanglement and superposition...

Quantum Computing

There are signs that we are approaching a technical revolution that might take humankind’s computational capabilities to a new level. Quantum Computing leverages the principles of quantum mechanics, enabling the computational power to solve...

Quantum computing: vision and challenges

A Compendium on Distributed Systems

Computer systems have evolved over the years starting from sizable, single-user, slow, and expensive machines to multi-user, fast, cheaper, and small-sized machines. The use of multi-user computer networks has given rise to a new paradigm o...

A policy framework for management of distributed systems

Policy-based management is one of the latest developments in network and distributed systems management. Academic and commercial settings, as well as standardisation bodies are concentrating on policy-based management as a very promising so...

A Formal Composition of a Distributed System Formal Composition of a Distributed System Formal Composition of a Distributed System Formal Composition of a Distributed System

Nowadays, information systems are becoming a vital and st rategic component of any organization. However, in most cases, these systems are designed and implemented without taking into consideration aspects. To ensure a certain level of secu...

Distributed Systems

This chapter addresses the issues involved in distributed databases, where a database is stored on more than one computer. It provides an introduction to parallel and distributed computing as a foundation for the better understanding of clo...

Distributed Systems

The origins of big data technologies come from database systems and distributed systems as well as data mining and machine learning algorithms that can process these vast amounts of data to extract the necessary knowledge. This chapter addr...

Developing a Self-Reflection Tool to Assess Schools’ Openness

In 2015, the EU Educational Policy document “Science Education for Responsible Citizenship” introduced the concept of Open Schooling as a promising approach to transform schools into innovation hubs within their local communities. In an ope...

A Behavioral SIQR-B Model for Cholera Transmission: Impact of Adaptive Risk Perception on Disease Dynamics

Background/Objectives: Cholera remains a major public health problem, particularly in regions with limited access to safe drinking water and sanitation. Traditional compartmental models may underrepresent adaptive human behavioral responses...

Conflicts in policy-based distributed systems management

Modern distributed systems contain a large number of objects and must be capable of evolving, without shutting down the complete system, to cater for changing requirements. There is a need for distributed, automated management agents whose ...

Policy hierarchies for distributed systems management

Distributed system management, involves monitoring the activity of a system, making management decisions and performing control actions to modify the behavior of the system. Most of the research on management has concentrated on management ...
