Enable the first examples of quantum advantage

We will have the first examples of quantum advantage using a quantum computer with an HPC. This integration of heterogeneous systems will lead to the development of a standard to allow seamless integration with classical systems across different quantum hardware vendors. Users will be able to run workloads that involve quantum and classical resources by writing quantum and classical code and deploying it in an integrated system. In 2026 and beyond, we will introduce new profiling tools to help users monitor, verify, and debug workloads across quantum and classical resources.

IBM Quantum Nighthawk is our platform for exploring and scaling quantum advantage ahead of large-scale fault-tolerant quantum computing. It uses a square lattice, connecting each qubit to up to four neighbors. Paired with techniques that reduce errors, Nighthawk is expected to run circuits with 7,500 gates in 2026 in with up to three 120-qubit modules (360 qubits), 10,000 gates in 2027, and 15,000 gates in 2028. As we improve and scale Nighthawk, we expect major progress toward quantum advantage.

IBM Quantum Loon debuted in 2025 with a new chip architecture that leverages c-couplers to link qubits across the chip, beyond nearest neighbors. It enables up to six degrees of connectivity between qubits. This improved connectivity is needed to implement IBM's scalable error-correcting code. This advancement strengthens our confidence in achieving large-scale, fault-tolerant quantum computing by 2029. In 2026, we will prototype our error correction decoder, which will enable real-time error correction--a key capability for scalable, fault-tolerant quantum computing.

We will continue to deliver improvements to dynamic circuits, error mitigation, and speed in the coming years to extend the capabilities of our available quantum systems.

We will introduce utility mapping tools that support the exploration and design of new algorithms by mapping problems to circuits that scale prior to fault tolerance. We will also work with partners to create a use case benchmarking tool, enabling others to explore which of their applications are ripe for near-term quantum value.

Patterns will begin to appear in workflows within the quantum advantage regime, providing the opportunity to start applying AI-driven automation to combine quantum and classical resources and set up and manage the components and configurations of these workflows. AI will also start driving improvements in quantum system setup and enhance the developer experience by enabling more efficient code development.

To prepare for the future, Kookaburra will demonstrate a single module out of Starling consisting of a logical processing unit and quantum memory.

Meanwhile, as the technology progresses toward large-scale, fault-tolerant quantum computing, the need for quantum-safe cryptographic protocols to protect data in flight and digital signatures intensifies. Cryptographically-relevant quantum computers may not arrive for some years but completing an inventory of cryptography in an organization, performing a risk assessment, migrating vulnerable cryptography, and implementing a crypto-agility framework will take several years. This, combined with harvest now, decrypt later threats, means enterprises needing strong data protection should already be evaluating and implementing an action plan.
