Fault-tolerant quantum computing (FTQC) remains the defining milestone of the quantum era — the point at which quantum systems can reliably solve problems beyond the reach of classical machines. But how close are we really?
In this high-level panel, leaders from some of the world’s most advanced quantum hardware companies will assess the state of the field: current qubit performance, scaling challenges, error correction breakthroughs, system architectures, and realistic timelines to fault tolerance.
From superconducting and trapped-ion systems to neutral atoms and photonics, panelists will compare technical approaches, discuss tradeoffs, and explore what must happen next — in engineering, materials science, cryogenics, control systems, and software — to move from today’s noisy intermediate-scale quantum (NISQ) devices to truly fault-tolerant machines.
Key questions include:
What technical hurdles remain before logical qubits outperform physical qubits?
How many physical qubits will meaningful fault tolerance actually require?
Are timelines converging — or diverging?
What milestones should industry and investors watch over the next 3–5 years?
Designed for researchers, industry leaders, investors, and policy stakeholders, this session will provide a candid look at progress, bottlenecks, and the roadmap ahead — separating momentum from hype in the race toward practical quantum advantage.
