D-Wave Unveils Fault-Tolerant Quantum Computing Plan: What's Ahead?

Read MoreHide Full Article

Key Takeaways

  • D-Wave targets 100 logical qubits by 2032, capable of performing more than 1 million operations.
  • QBTS plans systems in 2026, 2027 and 2028 with progressively larger error reduction factors.
  • D-Wave says dual-rail qubits can detect about 90% of errors and achieved 99.9% two-qubit fidelities.

D-Wave Quantum (QBTS - Free Report) or D-Wave is advancing its push toward commercial, fault-tolerant quantum computing. The company recently laid out a new gate-model roadmap, targeting 100 logical qubits capable of successfully performing over 1 million operations by 2032. The strategy builds on D-Wave’s expertise in high-coherence dual-rail qubits and quantum error correction, while leveraging its expertise in scaling and commercializing superconducting quantum systems.

At its first Investor Day on June 1, the company detailed a series of technical milestones underpinning this roadmap, including a 17-physical-qubit system in 2026 that supports logical error rates two times lower than physical error rates. D-Wave also expects to complete a 49-physical-qubit system in 2027, capable of a 20-fold error reduction factor and a 181-physical-qubit system in 2028 that can deliver a 2,000-fold error reduction factor.

Unlike many industry peers that focus on scaling physical qubits, D-Wave is pursuing an approach centered on reducing errors at the hardware level. Its dual-rail qubit architecture incorporates error detection directly into the qubits, allowing errors to be detected during computation at the single-qubit level. 

According to D-Wave, its dual-rail qubits can identify approximately 90% of errors as they occur, helping reduce the number of physical qubits required to perform error correction. This is in contrast to many other gate-model hardware modalities that cannot detect qubit errors. The company has also demonstrated 99.9% two-qubit fidelities with error detection, meaning physical errors occur only about one in every 1,000 operations.

Also, the roadmap calls for achieving a Lambda of 10, which D-Wave expects will reduce errors by a factor of 10 for each increment in error correction, making it possible to achieve fault-tolerant quantum computing with significantly fewer physical qubits.

What QBTS’ Peers Are Up To?

IonQ (IONQ - Free Report) , last month, marked the commercial launch of Interferometric Synthetic Aperture Radar (InSAR) capabilities through its space missions line. The offering enables millimeter-precision ground deformation monitoring with fully automated tasking and data delivery, allowing customers to detect and track physical change on the Earth’s surface consistently, at a frequency and scale never previously available from a commercial SAR provider. IonQ’s InSAR solution removes manual coordination and long revisit intervals.

IBM (IBM - Free Report) has announced plans to invest more than $10 billion in quantum computing over the next five years, spanning research and development, capital expenditure, manufacturing scaling, ecosystem partnerships and M&A. Collectively, these areas are designed to speed up IBM's quantum roadmap beyond its goal of delivering the first large-scale, fault-tolerant quantum computer in 2029 and bolster U.S. quantum leadership.
