Futuristic Actually, The Are Already Using Quantum Technology Every Day

(MENAFN- GetNews) Developed by researchers and industry across the Quantum Australia network

When most Australians hear the word“quantum”, they think of something futuristic. A lab experiment. A distant breakthrough. Perhaps something to do with quantum computers...?

But quantum technology is not confined to the future.

Quantum physics is the branch of science that explains how matter and energy behave at the smallest scales, inside atoms and subatomic particles. Over the past century, engineers have learned to harness that behaviour and build it into real systems that underpin critical infrastructure around the world.

Many of these are often described as“first-generation” quantum technologies, or systems built on well-understood quantum principles that have been engineered into reliable infrastructure over decades. It's the emerging wave that will constitute quantum's next wave, in areas like quantum computing, advanced sensing, and secure communications.

So how exactly does quantum physics affect everyday life now?

In more ways than most people realise.

Here are five real-world applications of quantum technology that are already embedded in modern life.

1. GPS relies on quantum atomic clocks

Every time you open Google Maps, track a parcel or order a rideshare, you are using quantum technology.

The Global Positioning System (GPS) works because satellites carry atomic clocks. These clocks measure time using energy transitions inside atoms and are accurate to billionths of a second.

That level of precision is essential. If atomic clocks were even slightly inaccurate, GPS errors would accumulate rapidly, reaching kilometres within a short period.

Navigation apps, aviation systems and emergency services all depend on this quantum timekeeping. [REMOVED THE SENTENCE ON IT BEING ONE OF THE EARLIEST TECHNOLOGIES]

2. MRI scanners use quantum physics

Modern medical imaging is another practical use of quantum physics.

Magnetic resonance imaging, or MRI, relies on a quantum property known as nuclear spin. When placed in a magnetic field, these particles respond in predictable ways that can be measured and translated into detailed images.

This allows doctors to see soft tissue clearly, monitor brain activity and diagnose injuries or disease without surgery.

MRI scanners are used in hospitals across Australia and around the world. They are a clear example of applied quantum technology improving health outcomes in everyday settings, and have led to many subsequent medical imaging technologies based on quantum.

3. Smartphones and screens depend on quantum semiconductors

The screen you are reading this on works because of quantum principles.

Smartphones, televisions and computer monitors rely on semiconductors designed around quantum behaviour. Electrons can only occupy specific energy levels inside materials. In light-emitting devices such as LEDs and OLED displays, when electrons move between those levels, they emit light.

That is how LEDs and OLED displays produce the images we see.

Without quantum semiconductor physics, modern electronics would not function as they do today. That includes everything from streaming a series to sending a message home.

While public attention often focuses on quantum computing, it is worth recognising that quantum-enabled devices have already shaped the digital economy for decades.

4. Financial markets depend on quantum timekeeping

Quantum technology also supports global financial systems.

Financial markets require precise time-stamping to coordinate transactions across continents. High-frequency trading, digital payments and settlement systems all rely on synchronisation with atomic clocks.

Shared, accurate time standards reduce disputes, enable regulatory compliance, and ensure transactions can be sequenced accurately across markets.

When your salary lands in your account or you tap your card at the supermarket, atomic clock synchronisation is quietly helping that transaction occur smoothly.

This is a practical example of how quantum technology supports economic stability and commercial activity.

5. Navigation beyond GPS uses quantum sensors

Quantum sensing is another applied technology beginning to move beyond research laboratories.

In environments where GPS signals are unreliable or unavailable, advanced navigation systems can draw on highly sensitive sensors that measure tiny changes in gravity, rotation and magnetic fields.

Advanced quantum sensors are therefore being developed to enhance navigation in these environments, with the aim of reducing drift and improving resilience in aviation, maritime, and defence applications.

These emerging technologies are also being explored beyond defence for commercial aviation safety, environmental monitoring, and medical diagnostics and are likely over time to operate quietly in the background of modern aviation and critical infrastructure.

Quantum technology is already embedded in modern life

The examples above are not speculative. They are operational systems in healthcare, finance, navigation, and communications.

Quantum computing often captures headlines, and it holds significant promise for areas such as drug discovery, advanced materials and climate modelling. But long before large-scale quantum computers become mainstream, quantum technologies such as atomic clocks, MRI scanners and quantum sensors are already delivering measurable value.

For Australia, this matters.

Australia has world-class quantum researchers and a growing ecosystem of startups and industry partners. As CEO of Quantum Australia, the national centre for quantum growth, I see firsthand how applied quantum technology is transitioning from research into commercialisation.

The next phase is not about proving that quantum physics works. That has already happened.

It is about scaling existing and emerging quantum technologies, integrating them into industry, strengthening national capability and ensuring Australia captures the economic and productivity gains that follow.

Quantum technology is not a distant promise. It already underpins GPS, medical imaging, and the precise time synchronisation systems that support digital payments and communications.

The future of quantum will build on systems that are already embedded in everyday life.
