Delft’s Quantware paves the way to the million-qubit quantum computer

Four months ago, Google presented a 105-qubit quantum chip hailed as a major breakthrough in quantum computing. Willow demonstrated an exponential reduction in error rates as the number of qubits is scaled up, solving a key outstanding challenge for quantum.

As impressive as Google’s feat is, however, it brushes over another key issue in quantum computing: the slow rate of scaling. “Willow showed a doubling of the number of qubits in five years. If we continue at that pace, it’ll take forever to achieve useful quantum computation,” says Matthijs Rijlaarsdam, CEO and co-founder of Quantware.
