What Are Spin Qubits?
IBM, Thursday, July 23rd, 2026
An IBM explainer on spin qubits, a quantum-computing approach that encodes information in electron spin.
This IBM Research explainer describes spin qubits, a class of qubits that encode quantum information in the spin state of individual electrons.
The piece outlines how the technology works, its potential advantages such as compactness and compatibility with semiconductor manufacturing, and the engineering challenges involved.
It situates spin qubits within the broader landscape of quantum-computing hardware approaches and IBM's ongoing quantum research.
