"Tunable Coupling Achieved Between Distant Superconducting Spin Qubits"

Researchers at Delft University of Technology have demonstrated strong and tunable coupling between two distant Andreev spin qubits, leveraging superconducting and semiconductor materials. This breakthrough could enhance the design flexibility and performance of quantum computers by enabling long-distance qubit coupling and closer packing of qubits. Future studies aim to improve coherence times by using cleaner semiconductor platforms.
