Is the quantum computer revolution really just five years away?
9 February 2018
Many of those involved in the race to unleash the power of quantum computing predict it will happen soon. Here's why, says Graeme Malcolm
We’ve figured out how to ensure quantum computers can be trusted
7 November 2017
Quantum computers will be useless if we can't trust their calculations. Now, two teams have programmed quantum systems to detect their own errors
Quantum code: why building the ultimate computer is the easy bit
1 November 2017
After decades of hype, quantum computers are poised to prove their superiority over classical machines. Now the race is on to figure out what to do with them
This qubit redesign may make it easier to make quantum computers
6 September 2017
Revamping the qubit to allow it to communicate across greater distances makes room for the electronics needed to power a quantum computer
Google on track for quantum computer breakthrough by end of 2017
22 June 2017
The search giant is testing a 20-qubit processor, its most powerful quantum chip yet, and says it will be able to outperform ordinary computers by the end of the year
Nanofridge could keep quantum computers cool enough to calculate
8 May 2017
Quantum computers need to be kept cool, just like regular computers, but an ordinary fan won’t cut it. A nanofridge that sorts electrons by temperature just might
