The potential for quantum mechanics to “revolutionise everything”


Liam Hall has recently shifted his job focus to technical areas, while he was a mechanic “getting greasy, scraped knuckles” while growing up on an Australian farm

He took a position with Australia’s national research organization, CSIRO, and is currently its director of quantum biotechnology.

“My background is a little strange. Being a diesel mechanic has always been my dream job. I wanted to major in engineering in college after doing that for a time. I was first exposed to physics and thereafter to quantum physics via it. His description is reminiscent of a rollercoaster experience.


To gauge patients’ iron levels, his group has been working on diagnostic tools, including microsensors made from 50 nanometer-sized diamond slivers—roughly 1,000 times finer than human hair.

The body’s iron storage system, ferritin, is now being monitored using current technologies. It would be more precise to quantify the iron levels within the protein rather than relying on ferritin as a proxy.


One approach would be to detect the iron’s minute magnetic fields. However, such strategy has a major flaw.

[The magnetic field] is completely tiny and outside the measurement of any traditional magnetometers or microscopes,” Dr. Hall points out.

But Dr. Hall’s quantum sensors, which are on the nanoscale, can detect and quantify such minute fields.

He claims that one day soon, technology will be able to detect and alert doctors to any illness, including cancer, by monitoring certain hormones or proteins.

“The advantage for quantum systems has always been that you can achieve much, much better sensitivity and easier identification of chemicals at a much lower cost,” according to Dr. Hall.

Quantum technologies are the focus of researchers from all corners of the globe

A worldwide effort to create quantum technology includes Dr. Hall. Different nations are attempting to take use of the peculiarities of quantum mechanics, including the United Kingdom, China, and the United States.

“Quantum is one of Australia’s most promising growth opportunities – a chance to create new markets, new applications,” said Prof Bronwyn Fox, head scientist of the CSIRO.

In the early 1900s, research into the tiniest things in nature gave rise to quantum mechanics. The scientific community feels optimistic about its ability to rapidly resolve complicated challenges and deepen our knowledge of the cosmos.

From cyber-security to novel medications to advancements in environmental research and decarbonization, the list of potential uses is almost endless. Possible solutions include molecules that “eat up carbon” and pull it out of the air, quantum batteries to power vehicles, emission-reducing planes, and improved transportation networks that alleviate traffic jams.

The potential for subatomic particles to act as data storage and processing medium is an aspiration of quantum computing researchers.

Qubits, the building blocks of quantum computers, may be either zeros or ones, or a mix of the two, in contrast to the bits used by traditional computers.

When particles are entangled with one another and may exist in more than one state at once (a phenomenon known as superposition), things start to get weird.

You can do computations that are physically impossible to do with classical computers by combining the quantum superposition principle with entanglement, another quantum phenomena. Prof. Andrew Dzurak of the University of New South Wales argues that it enables the prospect of conducting some fairly spectacular calculations that may be world altering.

Just picture a new strain of COVID or some other terrifying epidemic. You may use conventional experimental methods to determine its chemical structure; then, using a quantum computer, you can determine how to create a molecule that targets that particular virus.

“You solve that problem in a day rather than in the six or nine months that it took all of the greatest biological and pharmaceutical minds on the planet to come up with the vaccines for Covid.”

Dr. Muhammed Usman, a team leader at Data61, a division of CSIRO, claims that the natural phenomenon of entanglement is the source of the power that powers quantum computers.

It’s not simple and straightforward to understand. Particles with exceptional properties, such as photons or specks of light, may exist in two locations simultaneously and maintain a strong connection despite their lack of physical connection.

“I would say that nobody in the world fully understands the basics of entanglement,” is Dr. Usman’s honest view.

Would a quantum internet even be possible? I suppose so

Optical fibers may transmit data using light particles, making it almost hard to eavesdrop or hack.

At the Pritzker School of Molecular Engineering in Chicago, Professor David Awschalom constructed a 200km quantum network.
The University of Chicago in the United States has constructed a quantum network that is among the longest in the nation. A length of over 200 kilometers (124 miles) is being added to it.

At the Pritzker School of Molecular Engineering at the University of Chicago, David Awschalom holds the esteemed positions of Liew Family Professor of Molecular Engineering and Physics. He also helped establish the Chicago Quantum Exchange (CQE), a group of researchers at the University of Chicago that works with colleagues from Israel, the Netherlands, Japan, India, and Australia. In addition, the CQE is in charge of The Bloch Quantum Tech Hub, an alliance of businesses, universities, government agencies, and nonprofits that aims to produce $60 billion for the economy and 30,000 new quantum employment by the year 2035.

“We’ve extended how far we can send secure quantum messages through many miles of underground fiber,” according to him.

However, we must overcome substantial obstacles. To give just a few examples, in the realm of quantum computing, we’re aiming for scalability—the ability to add more qubits to a quantum system in order to solve more complicated problems—, error correction—the ability to detect and fix errors caused by decoherence—, and maintaining quantum coherence—the ability to keep a quantum system intact.

The promise of quantum computers is that they can tackle issues that classical computers just can’t handle. Extensive study into this topic will take years, yet it seems like the future is coming at us at a breakneck pace.

Among our team’s primary research foci is quantum artificial intelligence. “Quantum computing promises computational power, which is ideal for machine learning and artificial intelligence,” says Dr. Usman of the CSIRO.

Drones armed with deadly weaponry circling battlefields or self-driving automobiles are two examples. What does the future hold for AI? His conclusion was that “very reliable and trustworthy systems” were the result of combining AI with quantum computing.

“My dream come true would be that large-scale quantum computers are available and we can run quantum algorithms that I am developing to find solutions to the problems that we haven’t found yet, and that will revolutionise everything.”
