D-Wave Quantum said it is targeting a 100-logical-qubit gate-model system by 2032 that it says will be capable of more than 1 million operations, laying out a multi-step roadmap that begins with a 17-physical-qubit system in 2026 and expands to 49 physical qubits in 2027 and 181 physical qubits in 2028.
The company said the 2026 system is designed to produce logical error rates that are 2 times lower than physical error rates. By 2027, it expects its 49-qubit system to deliver a 20-fold error reduction factor versus the physical error rate. In 2028, D-Wave is aiming for a 2,000-fold error reduction factor, which it described as the scalable blueprint for fault-tolerant architectures.
The roadmap then calls for a 10-logical-qubit system in 2030, followed by the 100-logical-qubit system in 2032 that would support initial quantum chemistry and quantum AI applications.
D-Wave said its dual-rail qubits are designed to identify about 90% of errors as they occur, and that it has demonstrated 99.9% two-qubit fidelities with error detection, meaning physical errors occur about once in every 1,000 operations.
The company said its superconducting approach can run quantum error correction cycles 100 to 1,000 times faster than neutral atom or trapped ion systems. It also said it is targeting a lambda value of 10, compared with industry-wide demonstrations around 2, which would imply errors are reduced by a factor of 10 with each increment in error correction, rather than by about half. Today the company's shares have moved -4.31% to a price of $28.84. If you want to know more, read the company's complete 8-K report here.
