From Distributed Quantum Computing to Quantum Internet Computing: an Overview [PDF]
arXiv, 2022 The possibility of quantum computing has been proposed decades ago, at least as far back as the 1980s, and distributed quantum computing has been studied around two decades ago. Recent times have seen experimental successes and advances in quantum computer hardware and in quantum networking, leading towards the quantum Internet.

Spin-based quantum computation in multielectron quantum dots
, 2002 In a quantum computer the hardware and software are intrinsically connected because the quantum Hamiltonian (or more precisely its time development) is the code that runs the computer.

Simulating quantum mechanics on a quantum computer [PDF]
, 1997 Algorithms are described for efficiently simulating quantum mechanical systems on quantum computers. A class of algorithms for simulating the Schrodinger equation for interacting many-body systems are presented in some detail. These algorithms would make

Quantum Computer Using Coupled Quantum Dot Molecules [PDF]
, 1999 We propose a method for implementation of a quantum computer using artificial molecules. The artificial molecule consists of two coupled quantum dots stacked along z direction and one single electron.

Quantum Metropolis Sampling [PDF]
, 2010 The original motivation to build a quantum computer came from Feynman who envisaged a machine capable of simulating generic quantum mechanical systems, a task that is believed to be intractable for classical computers.

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.

Quantum Computing with Dartboards
The Journal of Physical Chemistry A, 2023 We present a physically appealing and elegant picture for quantum computing using rules constructed for a game of darts. A dartboard is used to represent the state space in quantum mechanics and the act of throwing the dart is shown to have close similarities to the concept of measurement, or collapse of the wavefunction in quantum mechanics.
