The Quantum Leap: Transforming Industries With Emerging Tech

Quantum technologies are moving rapidly from laboratory-scale experiments to real-world deployment, developing across three principal segments: computing, communication, and sensing. The year 2024 is regarded as a turning point for the field, as the focus has shifted from merely increasing the number of qubits to stabilising them — a signal that the technology is progressing towards becoming a reliable infrastructure component for mission-critical sectors.

Market growth shows strong momentum. The quantum computing market, valued at USD 1.4 billion in 2024, is projected to reach USD 4 billion by 2030 (19.4% CAGR) and USD 45–131 billion by 2040. Two distinct models are evident on the investment side: the United States presents a private-capital-led ecosystem driven by technology majors (Microsoft, Google, NVIDIA), whereas the European Union relies on a state-backed model with USD 13.5 billion in public-led investment. Global public investment reached USD 42 billion in 2023, with China maintaining its lead at USD 15.3 billion. Venture investment is maturing steadily; Series B rounds accounted for 62% of total investment value in 2023, with capital flowing predominantly to later-stage companies such as PsiQuantum (USD 1.2 billion).

Quantum computing comprises two core approaches: analogue (annealing) systems focused on optimisation problems, and general-purpose, gate-based digital systems. As a concrete illustration of hardware progress, D-Wave's Advantage2 system completed a magnetic-materials simulation in roughly 20 minutes — a task estimated to take a classical supercomputer more than one million years. Commercial value is becoming accessible through cloud services (Amazon Braket, Azure Quantum, IBM Qiskit). Early adopters are achieving measurable results: at the Port of Los Angeles, quantum-assisted optimisation delivered with D-Wave and SavantX produced a 60% increase in daily crane moves and a 30% reduction in crane travel distances, while Bosch applied Multiverse's quantum-inspired algorithms to production-line optimisation.

Quantum communication stands out as the segment with the nearest-term commercial opportunity, with its market expected to reach USD 10.5–14.9 billion by 2035 (23–25% CAGR). The principal driver of demand is the "Q-day" concern — that a sufficiently powerful quantum computer could break current encryption schemes such as RSA. The risk that malicious actors harvest encrypted data today to decrypt it in future ("store-now-decrypt-later") makes this threat relevant now. In response, NIST has published quantum-resistant cryptography standards (FIPS 203/204/205 and 207). As a concrete application, Banque de France and Deutsche Bundesbank trialled quantum-safe payment messaging between central banks under Project LEAP, conducting over 100 tests. Geographically, North America is expected to lead with a 32% market share by 2035, followed by Europe at 24% and China at 16%, the latter drawing on its strengths in satellite-based communication and long-distance QKD networks.

Quantum sensing, although the earliest-stage segment, has already produced functional devices such as atomic clocks, magnetometers, and gravimeters. Its market is expected to grow from USD 156.4 million in 2024 to approximately USD 1.34 billion by 2034 (~26% CAGR). Its strategic value is concentrated in defence and aerospace, where capabilities such as GPS-free navigation and high-precision detection are driving national investment. In this context, Infleqtion and L3Harris are developing quantum radio-frequency sensing systems based on Rydberg-atom technology for the U.S. Army. Healthcare (measurement of cardiac and neural signals), semiconductor diagnostics, and seismic monitoring are further prominent application areas.

Strategically, organisations are repositioning quantum computing from a distant decade-long horizon to a five-year, mid-term investment. The report proposes a staged roadmap comprising building awareness, identifying current challenges, developing in-house knowledge, running pilot projects, making strategic investments, and scaling successful pilots. The lowest-barrier, highest-return near-term action is assessed to be migration to quantum-resistant cryptography (PQC), which requires no quantum hardware, while quantum sensing is considered the most accessible hardware entry point given that commercial products already exist.
