Why do we need quantum computers and what will they be used for?
By Edd Gent published
Quantum computers will one day outpace the fastest supercomputers on the planet, but what will they be used to accomplish?

'Quantum CD' could hold up to 1,000 times more data than today's optical discs
By Peter Ray Allison published
The new study models how light spreads at the nanometer scale to understand how energy moves between rare earth emitters and the quantum defects within a solid material.

Scientists have built the smallest quantum computer in the world
By Keumars Afifi-Sabet published
The smallest machine of its kind in the world uses a single photon as its qubit and it can perform calculations without needing the cumbersome equipment to cool it down to near absolute zero.

Chinese scientists claim they broke RSA encryption with a quantum computer — but there's a catch
By Peter Ray Allison published
Researchers claim to have broken RSA encryption using a quantum computer, but what really happened?

Google's Sycamore quantum computer chip can now outperform the fastest supercomputers, new study suggests
By Keumars Afifi-Sabet published
Experiments on Google's 67-qubit Sycamore processor showed operations entering a new "weak noise phase" in which calculations were complex enough to outperform supercomputers, based on benchmark testing.

History of quantum computing: 12 key moments that shaped the future of computers
By Edd Gent published
Although quantum computing is a nascent field, there are plenty of key moments that defined it over the last few decades as scientists strive to create machines that can solve impossible problems.

What is a quantum processing unit (QPU)?
By Peter Ray Allison published
At the core of a quantum computer is the quantum processor, but these technologies are vastly different from the CPUs found in conventional computers.

What is a quantum bit (qubit)?
By Peter Ray Allison published
Qubits are the fundamental building blocks of quantum computers — and, when fitted into these machines — rely on the weird laws of quantum mechanics to process calculations in parallel.
