A huge investment in building an unproven quantum computer may help local science and industry, but the results are far from a sure thing.

A flawed paper shakes confidence in the foundations of ‘quantum-proof’ encryption – and highlights the need for a new generation of experts.
Quantum computing has huge promise from a technical perspective, but the practical benefits are less clear.
A new measurement of gravity at small scales hints at an alternative to billion-dollar experiments for the future of physics.
Quantum computers are proving extremely difficult to build, and there is no guarantee they will live up to their designers’ hopes.
Human behaviour is often irrational if viewed through the lens of “classical” physics and probability theory.
After decades of hype, quantum computers are on the verge of becoming useful. Here’s a refresher on why they’re such a big deal
Einstein’s theory of general relativity suggests that our universe originated in a Big Bang. But black holes, and their gravitational forces, challenge the limits of Einstein’s work.
Scientists show they can create quantum superpositions of sound particles, pointing to the potential for mechanical quantum computers.
Studying the brief and tiny quantum effects that drive living systems could one day lead to new approaches to treatments and technologies.
The enigma at the centre of our 20-year collaboration was how the Big Bang could have created conditions so perfectly hospitable to life
Countries around the world are racing to develop quantum technologies for computing, sensing and communication. Australia is trying not to get left behind.
A new way to make high-frequency light could make it easier to look at things 10 times smaller than conventional microscopes can see.
Our two best theories of nature, quantum mechanics and general relativity, are incompatible with each other in many ways – leaving physicists to dig deeper.
Life may be using quantum mechanics to its advantage.
According to a school of thought known as QBism, quantum mechanics is a guide to action.
Some physicists don’t believe that quantum mechanics is a perfect description of objective reality.
Some physicists believe we could one day find evidence of other universes.
If we accepted that the future could influence the past, we could get rid of many counter-intuitive aspects of quantum mechanics.
Examining microscopic quantum objects is exceedingly tricky, because their properties are connected to each other. But there could be a new method to measure them as accurately as possible.
