Silicon-based qubits have a clear advantage in race to million-qubit quantum computer thanks to tech that made Nvidia AI GPUs possible

Research hub IMEC has fabricated a functioning qubit network using High NA EUV lithography — the same cutting-edge manufacturing process behind Nvidia's AI chips — achieving qubit separations of just 6 nanometers. This exponentially increases coupling strength between quantum dots, addressing one of quantum computing's biggest hurdles: scalability. The breakthrough is compatible with existing silicon chip technology, raising the possibility of future chips containing millions of qubits.
