Many Worlds, the Cluster-state Quantum Computer, and the Problem of the Preferred Basis [PDF]
, 2011 I argue that the many worlds explanation of quantum computation is not licensed by, and in fact is conceptually inferior to, the many worlds interpretation of quantum mechanics from which it is derived. I argue that the many worlds explanation of quantum

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

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

Enhancing quantum teleportation efficacy with noiseless linear amplification
Nature Communications, 2023 Quantum teleportation constitutes a fundamental tool for various applications in quantum communication and computation. However, state-of-the-art continuous-variable quantum teleportation is restricted to moderate fidelities and short-distance ...

Measurement-based quantum computation on cluster states [PDF]
, 2003 We give a detailed account of the one-way quantum computer, a scheme of quantum computation that consists entirely of one-qubit measurements on a particular class of entangled states, the cluster states.

Defects in Quantum Computers [PDF]
Scientific Reports, 2018 AbstractThe shift of interest from general purpose quantum computers to adiabatic quantum computing or quantum annealing calls for a broadly applicable and easy to implement test to assess how quantum or adiabatic is a specific hardware. Here we propose such a test based on an exactly solvable many body system–the quantum Ising chain in transverse ...

Topological Quantum Computation [PDF]
, 2001 The theory of quantum computation can be constructed from the abstract study of anyonic systems. In mathematical terms, these are unitary topological modular functors. They underlie the Jones polynomial and arise in Witten-Chern-Simons theory.

Universality in quantum computation [PDF]
Proceedings of the Royal Society of London. Series A: Mathematical and Physical Sciences, 1995 We show that in quantum computation almost every gate that operates on two or more bits is a universal gate. We discuss various physical considerations bearing on the proper definition of universality for computational components such as logic gates.

Blind Quantum Computation [PDF]
, 2006 We investigate the possibility of "having someone carry out the work of executing a function for you, but without letting him learn anything about your input".
