By applying magnetic fields in specific directions to silicon quantum dots containing single trapped holes, they achieved enhanced coherence times without sacrificing operation speed. The team successfully tuned two qubits to the same sweet spot, demonstrating scalability potential. This approach addresses a major challenge in quantum computing where spin-orbit coupling makes hole spin qubits vulnerable to electrical disturbances that cause decoherence and information loss. Future work will focus on tackling magnetic noise from nuclear spins in the material. ## Full article daily.dev links to this article rather than hosting it.
