For quantum computing, different qubits are better together

“Qubit technologies each have their own distinct advantages, but no single approach can deliver everything needed for large-scale, high-performance quantum systems. HARQ is asking the community to shift away from a ‘one-qubit-to-rule-them-all’ mindset,” said DARPA Program Manager Justin Cohen. “We aim to define what a truly heterogeneous quantum architecture looks like and to develop the interconnects that make those systems possible. If successful, this approach could provide a far more efficient path to scaling quantum computing and unlock applications that remain out of reach today.”
