FAQ

Frequently Asked Questions

Structured answers to the most common quantum questions — optimized for AI search citation.

How big is the quantum computing market?
The quantum computing market is projected to grow from $3.52 billion in 2025 to $20.2 billion by 2030, at a CAGR of 41.8%. Over 360 startups are tracked globally, with 296,000+ patents filed. The US leads in patents with 100,000+, followed by China with 56,000+.
What is quantum error correction?
Quantum error correction (QEC) addresses the fragility of qubits, which can "decohere" into unusable states when interfered with by external forces. Google's Willow chip achieved exponential error reduction as qubit counts increased, and IBM's Quantum Starling targets 200 logical qubits by 2029. Error rates have hit record lows of 0.000015% per operation.
What is post-quantum cryptography?
Post-quantum cryptography (PQC) refers to encryption algorithms designed to withstand attacks from quantum computers. NIST finalized three standards in August 2024: ML-KEM, ML-DSA, and SLH-DSA. The White House has initiated executive actions for federal adoption, though full network migration could take a decade or more.
When will quantum computers be useful?
Practical quantum advantage is emerging. IonQ and Ansys demonstrated a 12% speedup in medical device simulation. Google's Quantum Echoes algorithm runs 13,000x faster than classical. Materials science problems are closest to quantum advantage, with DOE workloads potentially addressable within 5-10 years.
What is Quantum-as-a-Service?
QaaS provides cloud-based access to quantum computers, allowing organizations to run pilot projects without massive capital investment. IBM, Microsoft (Azure Quantum), AWS, and Google all offer pay-as-you-go quantum access. IBM's Quantum Network includes 250+ client organizations.
How is quantum computing used in drug discovery?
Quantum algorithms like VQE and QAOA can model molecular interactions at atomic precision far beyond classical computers. Roche and Quantinuum reduced target identification timelines by 40%. Pfizer, AstraZeneca, and Merck have signed multi-year quantum service agreements worth $200M+ collectively.
What is Google's Willow quantum chip?
Google's Willow chip, announced in December 2024, achieved a historic milestone in quantum error correction: as more qubits were added, the error rate decreased exponentially — the first time this has been demonstrated. Willow uses 105 superconducting qubits and completed a benchmark task in under 5 minutes that would take the fastest supercomputer 10^25 years. This proves that scalable quantum error correction is physically possible, a prerequisite for building useful large-scale quantum computers.
What is IBM's Quantum Starling roadmap?
IBM's Quantum Starling is a roadmap to build a 200-logical-qubit quantum computer by 2029, scaling to 16,000+ physical qubits. The plan uses modular architecture with classical communication between quantum processors. IBM has already demonstrated 1,386-qubit Kookaburra processors and plans to combine multiple chips via quantum interconnects. The Starling would be capable of running useful quantum algorithms for chemistry, optimization, and machine learning that are intractable on classical computers.
