Explaining Quantum

In collaboration with the team from The Economist who organise the Commercialising Quantum Global Conference, we delve into exactly what Quantum is, why you need to know about it, the trends and what to expect at the 2025 edition of the conference. 

Can you explain, to those not in the know, what quantum is? 

Quantum refers to a class of technologies that harness principles of quantum mechanics — an area of physics that governs the behaviour of matter at the atomic and subatomic scale. Unlike classical technologies, which rely on binary systems (0s and 1s), quantum technologies exploit phenomena such as superposition and entanglement to process and transmit information in fundamentally new ways. The field encompasses quantum computing, quantum communications, and quantum sensing, each offering the potential to outperform classical systems in specific, high-impact domains.

Who needs to know about quantum and why?

Quantum is no longer the exclusive domain of physicists. It is now relevant to decision-makers across industries—from financial services and healthcare to energy, logistics, and national security. As the technology matures, business leaders, policymakers, and investors must understand where and when quantum will deliver value. Those who fail to engage now risk missing the early commercial inflection points or being unprepared for its disruptive consequences.

What are some of the key current trends when talking about your sector?

Several themes dominate the current quantum landscape:

• Commercial viability: The shift from theory to practical use cases, with growing pressure to demonstrate return on investment.
• Hardware progress vs. hype: Distinguishing meaningful breakthroughs from overstated claims remains critical.
• Talent bottlenecks: A shortage of quantum-literate professionals is slowing adoption across sectors.
• Policy and governance: Governments are ramping up investment and regulation, raising questions about standardisation, security, and international collaboration.
• Quantum-readiness: Organisations are beginning to assess how quantum will integrate into existing infrastructure and long-term strategy.

What should people be excited about when attending Commercialising Quantum Global?

Commercialising Quantum Global is not a typical academic conference. It focuses on real-world applications, measurable returns, and actionable insights. Attendees will hear directly from end-user industries applying quantum to critical problems — from drug discovery to power grid optimisation.

The event also offers a rare opportunity to engage with policymakers shaping national and international quantum strategies, providing context that is often missing from purely technical events.

What are some of the key sessions to attend at the event this year?

This year’s programme addresses both opportunity and obstacle. Highlights include:

• Quantum-powered SDGs: a path to 2030 – exploring how quantum can support global development goals
• What is the expected timeframe from quantum utility to advantage? – a frank assessment of progress and expectations
• The superposition of impact and hype – a session focused on separating commercial promise from premature projections
• Let’s get entangled: fostering international collaboration and alliances – addressing the urgent need for cross-border standards and infrastructure
