The quantum nature of light can be harnessed for a variety of purposes.
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.
Plus new research finds a way to speed up the search for dark matter. Listen to episode 4 of The Conversation Weekly.
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.
Nobody expected that allowing more communication would make computational problems more reliable.
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?
