Intel and QuTech Demonstrate High-Fidelity ‘Hot’ Qubits

Intel, in collaboration with QuTech, today published a paper in Nature demonstrating the successful control of “hot” qubits, the fundamental unit of quantum computing, at temperatures greater than 1 kelvin. The research also highlighted individual coherent control of two qubits with single-qubit fidelities of up to 99.3%. These breakthroughs highlight the potential for cryogenic controls of a future quantum system and silicon spin qubits, which closely resemble a single electron transistor, to come together in an integrated package.
