Today, Sunday 14 April marks World Quantum Day, a moment dedicated to appreciating the profound mysteries and potentials of quantum science. Quantum mechanics isn’t just for complex labs and supercomputers, it’s a basic part of all of us.

Quantum science is not just around us, it’s inside us, affecting our energy. Every cell in our body uses quantum mechanics to turn food into energy, send nerve signals and move our muscles. It’s like a tiny quantum world inside us, controlling vital life processes. This shows that our lives and health are deeply connected to the quantum world.

What is quantum science?

At its core, quantum science explores the behaviour of particles at the smallest scales imaginable, think atoms and subatomic particles like electrons and photons. It’s a realm where the usual rules of physics twist and turn in curious ways. Particles can be in multiple places at once, communicate instantly over vast distances and behave unpredictably.

Quantum mechanics in our daily lives

Now, let’s get personal. Quantum mechanics doesn’t just operate in a vacuum, it’s integral to the very building blocks of life. Every time you look at something, quantum mechanics is at play. The light that enables us to see the world is made up of photons, tiny packets of energy behaving according to quantum rules.

Consider your sense of smell. Scientists believe that our noses may detect scent by sensing the quantum vibrations of molecules. It’s like each molecule has its little quantum fingerprint that our noses can read.

The quantum brain?

The brain, an enigmatic organ, dips into the quantum world too. Some researchers speculate that our brains might use quantum computing principles to perform complex calculations. While this is still a theory, it underscores how deeply quantum mechanics might be woven into the essence of our existence.

Quantum mechanics and health

On a more tangible level, quantum mechanics is revolutionising medicine. Techniques like magnetic resonance imaging (MRI) rely on quantum behaviour to peer inside the human body with remarkable clarity. Future medical technologies might harness quantum mechanics for even more precise diagnostics and treatments.

Embracing the quantum within

World Quantum Day isn’t just about celebrating the achievements of scientists. It’s about recognising how these quantum underpinnings play a crucial role in our lives and our understanding of the universe.

As we go about our day, let’s remember that the quantum world isn’t just the domain of physicists, it’s a fundamental part of us all. Whether it’s helping us see, smell or maybe even think, quantum mechanics is as close as it gets, it’s literally in every breath we take.

Today, let’s celebrate not just the science, but also the mysterious, quantum connection that ties all of life together. How wondrous it is to think that deep down, we all are a little bit quantum!
