Spin-based quantum computers made by chemistry: hows and whys

Abstract

This introductory review discusses the main problems facing the attempt to build quantum information processing systems (like quantum computers) from spin-based qubits. We emphasize ‘bottom-up’ attempts using methods from chemistry. The essentials of quantum computing are explained, along with a description of the qubits and their interactions in terms of physical spin qubits. The main problem to be overcome in this whole field is decoherence—it must be considered in any design for qubits. We give an overview of how decoherence works, and then describe some of the practical ways to suppress contributions to decoherence from spin bath and oscillator bath environments, and from dipolar interactions. Dipolar interactions create special problems of their own because of their long range. Finally, taking into account the problems raised by decoherence, by dipolar interactions, and by architectural constraints, we discuss various strategies for making chemistry-based spin qubits, using both magnetic molecules and magnetic ions.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
