Quantum computing expert Daniel Lidar explains what problems scientists are still trying to overcome to make quantum computing useful.
Quantum computers can explore every possible solution to a problem at the same time.
You’ll be hearing a lot about quantum computing in 2025. Here’s where the field is at – and where it’s all going.
Three Conversation science editors look ahead to what to expect in 2025 on The Conversation Weekly podcast.
Here are some of the changes in technology we can expect to see in 2025.
An ‘80s-style accord may be the best way to find consensus in the uncertain and divided arena of quantum technology.
Researchers are studying how quantum computers can help optimise net-zero power grid operation and expansion planning.
Quantum information theory is the field behind quantum computing, but experts in this field are also applying their way of thinking to some big questions in quantum physics.
Universities and colleges nationwide are beginning to investigate quantum education to develop a workforce ready for quantum technology.
Tech giants, major powers and top research universities are all in a race to build viable quantum systems. Why now?
Novel metaphors can make it easier to understand complex concepts such as quantum computing.
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 computers that work at slightly higher temperatures could be cheaper and more accessible.
Quantum computing has huge promise from a technical perspective, but the practical benefits are less clear.
End-to-end encryption provides strong protection for keeping your communications private, but not every messaging app uses it, and even some of the ones that do don’t have it turned on by default.
Quantum computers are proving extremely difficult to build, and there is no guarantee they will live up to their designers’ hopes.
Several companies have made quantum computers, but these early models have yet to demonstrate quantum advantage: the ability to outstrip ordinary supercomputers.
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
