Quantum machine learning models could help us create AI systems that are almost impenetrable by hackers. But in the hands of hackers, the same technology could wreak havoc.
Countries around the world are racing to develop quantum technologies for computing, sensing and communication. Australia is trying not to get left behind.

Superconductors make highly efficient electronics, but the ultralow temperatures and ultrahigh pressures make them costly and difficult to use. Room-temperature superconductors promise to change that.
Computers are growing more powerful and more capable, but everything has limits.

In the age of AI, people might wonder if there’s anything computers can’t do. The answer is yes. In fact, there are numerous problems that are beyond the reach of even the most powerful computers.
Against quantum cyber attacks, one can use smarter softwares, or encrypt communications differently in terms of hardware.

China and the US are racing for quantum technology breakthroughs in weapons, communications, sensing, and computing that could tilt the balance between the world’s military forces.
So far researchers have only been able to control a handful of qubits — the basic units of information in a quantum computer. A new approach could help them control millions at a time.
The focus of quantum science has shifted from theoretical physics to the advent of new technologies such as quantum computers. The benefits could be immense, but there are also potential pitfalls.

Researchers have found a way to speed up the search for dark matter using technology from quantum computing. By squeezing quantum noise, detectors can now look for axions twice as fast.
For 60 years, physicists thought they knew exactly how coherent a laser could get. Now the ultimate quantum limit to laser coherence has been found, and it’s much much bigger than anybody thought.
Quantum computers may be more trustworthy.
