Generating energy usually means wasted heat. Semiconductors let the electrons flow with zero waste – but so far scientists only know how to get them to work at ultra-low temperatures.

A quantum technology boom is coming, and Australia must act to avoid missing out. A new CSIRO roadmap plots a course for this new industry.
Quantum communication is needed to make the internet much more secure.
A paper published by researchers at Google claimed that they had achieved computing quantum supremacy, but leaks and counter-claims have created a stir.
Google claims quantum supremacy – IBM says not so fast. One researcher explains why he doesn’t see quantum computers outpacing classical computers any time soon … and maybe not ever.
On October 23 Google announced that it built a quantum computer thousands of times faster than classic computers. This could have immense impacts on finance, cryptography and other fields.
A quantum experiment raises deeply philosophical questions about the fundamental nature of reality.
Quantum computers aren’t about to take over, but this is an important milestone.
Most quantum computers require a near perfect vacuum, extremely low temperatures and no disturbances to operate. They are also hard to scale up.
A leaked research paper shows that quantum computer researchers may have overtaken conventional ones for the first time
Manufacturing quantum computers would be a lot easier with existing technology than the exotic components currently used to build them.

Quantum machine learning is an exciting, rapidly growing field.
The head of Google’s Quantum AI Labs, Hartmut Neven, claims the current speed of development means a quantum computing breakthrough is near.
Quantum machine learning is an exciting and rapidly growing field.
Computers were once considered high-end technology, only accessible to scientists and trained professionals. Today, almost everyone has one. Will quantum computing follow the same path?
Quantum computers are set to revolutionise technology, but very few people know how to use them.
Combining quantum computing with neural networks could produce AI that can make very complex decisions quickly.
It is hard to predict when quantum computers will be strong and fast enough to crack the codes that keep bitcoin safe. But that day is coming.
Physicists have designed an electrical component that breaks time-reversal symmetry. Not quite the time machine from Hollywood but it should help with communication technology and quantum computing.
