Moveable quantum dots offer flexible, scalable qubit networking

Researchers from Delft University of Technology and QuTech demonstrated a chip in which spin qubits hosted in a linear array of quantum dots can be moved along tracks to a shared interaction zone, enabling entangling two-qubit gates and teleportation. The device achieved over 99% fidelity for two-qubit gates and about 87% teleportation success on a six-dot setup, suggesting a path to mix bulk manufacturing with flexible qubit connectivity—though larger-scale hardware and higher performance are still needed before practical, error-corrected quantum computing is feasible.
