Comparing Qubit Platforms in the Race to Feasible Quantum Computing

Abstract

Quantum computing is an emerging field that has been attracting a substantial amount of interest in the scientific community lately due to the advantages of quantum information processing. The fundamental unit of quantum information that makes up a quantum computer is a qubit. Several platforms have been proposed as physical realisations of these qubits for the purpose of making quantum computing a feasible technology, yet no one platform has significantly outperformed the others. This literature review discusses the current state of the field of quantum computing, by comparing and contrasting some of the most promising qubit platforms of today. By doing so, this paper analyses each of their feasibilities for full-scale quantum computing in the future and maps out a possible trajectory for how quantum computing may progress in the next few years
