Kawasaki, Japan, March 24, 2025 - Fujitsu Limited today announced the world’s first demonstration of a complete universal quantum gate set for diamond spin qubits with an error probability below 0.1%, achieving a fidelity among the highest reported over all quantum hardware technologies. This collaboration with QuTech, a leading quantum technology research institute of Delft University of Technology (TU Delft), marks an important step for the diamond spin method towards carrying out quantum error correction and realizing practical quantum computing. The findings were published in Physical Review Applied on March 21, 2025. The newly developed technology utilizes high-purity diamonds to create a stable two-qubit system comprising an electron spin and nitrogen nuclear spin within a nitrogen-vacancy (NV) center (2) , a kind of atomic defect that can be harnessed for quantum computing. The team used advanced techniques to eliminate the impact of environmental noise on qubits ...
