Mark W. Johnson

SVP Gate Model Products and Technology D-Wave Quantum

Mark W. Johnson has been involved in the development and commercialization of technology for more than 25 years, and currently leads the development gate model products and technology at D-Wave. Mark joined D-Wave in 2005 as an experimental physicist and superconducting circuit design engineer to help develop, build, and deliver the world's first commercially available quantum computer. Since then he has continued to work with the D-Wave team to develop and release subsequent generations of quantum computers. Prior to joining D-Wave, Mark was a scientist with the Superconductive Electronics Organization at the Space Park facility of Northrop Grumman, formerly TRW, Inc., developing superconductive analog-to-digital converters and digital signal processors for communications applications. Mark holds a doctorate in physics from the University of Rochester.

DAY 1 THURSDAY JUNE 25TH

10:20 AM Keynote Panel: Where are we on the path to FTQC?

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.
