IQM Quantum Computers Unveils Development Roadmap Focused on Fault-tolerant Quantum Computing by ...
IQM Quantum Computers (IQM), a global leader in
superconducting quantum computing, today announced its development roadmap with
technical milestones targeting fault tolerant quantum computing by 2030, while
enabling a dedicated Noisy Intermediate-Scale Quantum (NISQ) approach for
near-term usage.
Since its start, IQM has successfully delivered full-stack
quantum computers based on its first three processor generations. IQM's 12-year
roadmap reflects its vision for pioneering quantum solutions through novel
algorithmic approaches, modular software integration, and scalable hardware
advancements. It leverages the company's ability to design and fabricate
next-generation quantum processors with seamless integration into full-stack
systems controlled by an open software stack.
IQM's unique co-design capabilities steer the roadmap towards
efficient error-correction implementations with high system performance by
merging IQM's two processor topologies IQM Star and IQM Crystal. To enable the
roadmap, IQM systematically invests in its R&D, testing and fabrication
facilities to boost technology scaling up to 1 million qubits while maintaining
high qubit quality and gate fidelity.
To support the developer community and to ease the usage of
quantum computing, IQM will also enable tight high-performance computing (HPC)
integration and create a special software development kit (SDK). Open
interfaces will empower the ecosystem, including quantum error mitigation,
co-develop libraries and use-cases on IQM’s quantum computers.
The company aims to achieve quantum advantage across multiple
industry domains, focusing on quantum simulations, optimization, and quantum
machine learning. According to a McKinsey report,
these selected use-cases will unlock a value potential of more than US$28
billion by 2035.
Quantum advantage will be provided by fully error-corrected
systems with hundreds to thousands of high-precision logical qubits, for which
error correction will be enabled by efficiently implementing novel quantum
low-density parity-check (QLDPC) codes. This approach reduces the hardware
overhead by a factor of up to 10 compared to surface code implementation.
Furthermore, IQM is targeting high-precision logical qubits with
error rates below 10^-7, enabling quantum advantage for applications demanding
exceptional accuracy, such as in chemistry and materials science.
“We are implementing Quantum low-density parity-check (QLDPC)
codes through a novel chip topology, enabled by our uniquely connected Star
topology, long-distance couplers and a very compact approach for advanced
packaging and signal routing,” said Dr. Jan Goetz, Co-Founder and Co-CEO
of IQM Quantum Computers. “This underlines our commitment to hardware
efficiency, enabling a feasible and scalable pathway to fault tolerance
combined with an open and modular software architecture.”
Goetz emphasizes that the company’s proprietary cleanroom
facilities will support the fabrication of complex processors with unique
long-range connections, facilitating high-performance quantum processors.
To this end, IQM will implement novel solutions for advanced
packaging and 3D integration to ensure scalability while maintaining its
ambitious goals to reduce error rates, while its large-scale processors will be
built up in a modular way and powered by cryogenic electronics. The results are
reduced heat load, strongly miniaturized packaging solutions, and reduced cost
per qubit. These features will result in more performant and affordable
products for IQM's customers in the HPC and enterprise market.
Offering on-premises and cloud access, IQM has been specializing
in integrating quantum systems into HPC centers since 2020. The latest is
Germany’s first hybrid quantum computer at the Leibniz Supercomputing Centre.
