The longer horizon — sensing, networks, simulation.

Beyond cryptography and computing: the three quantum domains on longer timelines that have nonetheless made substantial progress and are moving fast.

This white paper has focused primarily on the implications of quantum cryptography, computing, and the regulatory and IP environment around both. But quantum is a broader research field than any single application. Quantum sensing, networks, and simulation are on longer timelines but have made substantial progress and are moving fast.

A. Quantum Sensing

Quantum sensors exploit the sensitivity of quantum states to measure environmental conditions with precision unattainable by standard instruments. Quantum-based sensing technologies are directly applicable to verticals like medical imaging, navigation, and industrial and environmental measurement.

Medical imaging. The quantum-sensing medical-imaging market was approximately $344 million in 2025 and is projected to reach roughly $661 million by 2034. Global Insight Services projects a broader quantum-sensing healthcare market growing to over $4 billion by 2034. Magnetocardiography — the measurement of magnetic fields generated by the heart's electrical activity — is one of the most mature clinical applications. SandboxAQ's CardiAQ system is in clinical studies with Mayo Clinic, UCSF Medical Center, and Mount Sinai, with FDA clearance targeted. Nitrogen-vacancy diamond magnetometers, optically pumped magnetometers (OPMs), and superconducting quantum interference devices (SQUIDs) are each advancing toward clinical deployment for cardiac, fetal, and neurological imaging.

Navigation and positioning. Quantum accelerometers, gyroscopes, and atomic clocks offer GPS-independent navigation, a capability of obvious interest to aerospace, maritime, defense, and autonomous-vehicle sectors. Several national defense programs are funding development, and the first commercial pilots in regulated industries are underway.

Industrial and environmental measurement. Quantum gravimeters, magnetometers, and gas-composition sensors are entering commercial use in geophysical surveying, pipeline and unexploded-ordnance detection, and certain categories of environmental monitoring. The early competitive dynamics resemble the early stages of commercial LIDAR: the sensors work, and the question is who builds them into products that reach scale.

B. Quantum Networks

Quantum networks use quantum states of light to distribute cryptographic keys and link quantum computers into a distributed computational fabric. The near-term commercial form is Quantum Key Distribution (QKD) — a method for distributing encryption keys with security guarantees grounded in physics. Several national networks exist in some form, particularly in China, where a state-backed Beijing–Shanghai QKD backbone has been operational for several years, and the European Union's “EuroQCI” initiative is building a continental quantum-communications infrastructure. Commercial deployments to date are mostly in banking, government, and defense applications with specific high-confidentiality requirements.

For most enterprise boards, QKD is not yet a procurement decision. It is a strategic-awareness item: if the company operates in a sector where stakeholders or regulators are evaluating QKD, the organization should develop a position and, if applicable, an associated roll-out plan.

C. Quantum-Accelerated Simulation

The simulation category overlaps with the drug-discovery and materials examples in Section VIII, but deserves a separate mention because of how fast it is moving. In 2025, D-Wave reported the first claim of industrially relevant quantum supremacy: a programmable materials simulation that, the authors argued, would have required roughly a million years of runtime on a current supercomputer. Whether this claim survives public scrutiny, the broader trajectory is clear. Materials science, chemical engineering, climate modeling, and certain classes of financial simulation are among the domains where quantum-accelerated computation is expected to generate the earliest genuine commercial advantage, and the first peer-reviewed results are now landing in the literature.

D. Why This Belongs on the Board's Radar Now

No board needs to act on any single item today. What the c-suite and board do need to establish is a regular briefing cadence, at a frequency defined by the organization's needs, that ensures the company is on solid footing to act to ensure its short- and long-term quantum resiliency. Each quantum application discussed in this paper has reached or is approaching its commercial inflection points that will continue to move faster than most incumbents expected. Organizations that follow the principles outlined in this paper are doing what the governance framework in Part I and the strategic framework in Part II together demand: they are engaging informedly with a mission-critical category, documenting the engagement, and positioning the organization to respond as the picture changes.
