Five Ways Quantum Technology Could Shape Everyday Life
Quantum technology is rapidly moving from theoretical breakthroughs to practical applications, promising to transform a variety of industries and daily experiences. Recent developments, such as IBM unveiling two new quantum supercomputers and Denmark’s ambition to build one of the world’s most powerful commercial quantum computers, highlight the accelerating pace of this transition. Experts from RAND Europe—Salil Gunashekar, Adam Urwick, and Teodora Chis—outline five key areas where quantum technology could soon have significant impacts.
Understanding Quantum Technology
At its core, quantum technology leverages the strange and counterintuitive laws of quantum mechanics, the branch of physics that explains the behavior of matter and energy on the smallest scales. Phenomena such as superposition—the ability of particles to exist in multiple states simultaneously—and entanglement—where particles remain connected across vast distances—are not just abstract theories anymore. Engineers are harnessing these effects to develop groundbreaking systems including quantum computers, sensors with unprecedented precision, and communication networks that resist hacking.
Here are five ways quantum technologies are expected to shape everyday life:
- Discovery for Medicine and Materials Science
Drug discovery and materials research involve analyzing thousands of molecular and atomic combinations, a task that challenges even the fastest classical supercomputers. Quantum computers utilize quantum bits or qubits, which can exist in multiple quantum states beyond the simple 1s and 0s of traditional computing bits. This allows quantum computers to simulate numerous possibilities simultaneously and identify patterns inaccessible to classical computation.
In healthcare, this means faster drug discovery processes, enabling quicker responses to outbreaks, personalized medicine, and better understanding of complex biological interactions. Similarly, quantum simulation can accelerate the development of new materials such as high-efficiency energy solutions, catalysts, and alloys that could contribute to reducing transport emissions and improving sustainability.
Though commercially viable, fully operational quantum computers are still in development, hybrid quantum-classical systems are already demonstrating considerable potential to revolutionize medicine and materials science.
- Sensors for Navigation, Medicine, and the Environment
Quantum sensors exploit superposition and entanglement to detect minute changes that conventional instruments cannot perceive. Their applications span across various fields:
Navigation: Quantum sensors could enable ships, submarines, and aircraft to navigate without GPS by detecting subtle variations in Earth’s magnetic and gravitational fields. This can provide reliable guidance even when satellite signals are unavailable or compromised.
Medicine: In healthcare, quantum-enhanced sensors might offer faster, more sensitive, and noninvasive imaging techniques, improving diagnostics and patient care.
Environmental Monitoring: Quantum sensors could provide early warnings for seismic activity by tracking delicate shifts beneath the Earth’s surface. Additionally, they may detect trace pollutants in air and water with extraordinary accuracy, aiding environmental protection efforts.
- Optimisation for Logistics and Finance
Many complex optimization challenges—such as managing power grids, scheduling flights, coordinating global deliveries, or handling investment portfolios—involve selecting the best option from billions of possibilities. Even advanced classical supercomputers struggle to quickly find efficient solutions to such problems.
Quantum computing promises to transform these sectors by using algorithms that explore many potential solutions simultaneously. This could enable:
Dynamic adjustment of delivery routes based on real-time traffic, weather, and demand changes.
Airlines and rail networks to automatically reconfigure schedules to prevent cascading delays.
Energy providers to better balance renewable generation and consumption.
Financial institutions to evaluate numerous market scenarios in parallel, leading to improved portfolio management.
- Ultra-Secure Communication
The increasing capabilities of quantum computers threaten many current encryption methods, such as RSA encryption used widely to secure data transmission online. This poses a significant cybersecurity challenge for governments, businesses, and individuals alike.
Quantum communication techniques like quantum key distribution (QKD), however, offer a way to secure communication intrinsically, making it virtually impossible to intercept or hack. This technology has immediate implications for safeguarding:
Financial transactions
Health records
Government and military communications
For national security agencies, quantum-safe encryption is already a strategic priority. For the general public, this could translate into enhanced digital privacy, more trustworthy identity verification systems, and a reduced risk of cyberattacks.
- Supercharging Progress in Artificial Intelligence (AI)
Artificial intelligence continues to reshape industries but depends heavily on massive computing power, especially in training large models. Quantum computing holds the potential to accelerate AI development by handling complex calculations beyond the reach of classical machines.
While still nascent, quantum algorithms may improve machine learning processes, simulate complex systems more efficiently, and optimize AI architectures. The outcomes could include AI systems that learn faster, better understand context, and process larger datasets—enabling smarter AI assistants, real-time medical diagnostic tools integrating genomic and environmental data, and expedited scientific research through quantum-boosted simulations.
Why This Matters and What to Watch
Quantum technology is no longer a distant theoretical prospect. With billions in global investment and increasing numbers of prototypes moving beyond the lab, the “quantum era” is emerging. The implications span healthcare, energy, finance, national security, and beyond.
Governments recognize the strategic importance of quantum technology, while industries view it as a competitive edge. This raises critical questions about whether education systems, workforce skills, infrastructure, and governance mechanisms are prepared for the coming changes.
Early and strategic investment in quantum readiness will be crucial in shaping how this transformative technology evolves and integrates into our connected, data-driven world. Though widespread impact may still be years away, quantum technology promises to revolutionize many facets of everyday life in the near future.
