Using microwave beams could let quantum computers be small but mighty

13 August 2021

A decades-old theory to simplify silicon quantum processors has been shown to work, potentially paving the way for vastly more powerful quantum devices

Google researchers made a time crystal inside a quantum computer

3 August 2021

A time crystal is a unique phase of matter that flips between two configurations with no energy input necessary – first proposed in 2012, this type of matter has now been created inside a quantum computer built by Google

Google demonstrates vital step towards large-scale quantum computers

14 July 2021

Google has shown that its Sycamore quantum computer can detect and fix computational errors, an essential step for large-scale quantum computing, but its current system generates more errors than it solves

China beats Google to claim the world's most powerful quantum computer

5 July 2021

A team in China has demonstrated that it has the world's most powerful quantum computer, leapfrogging the previous record holder, Google

Quantum data link established between two distant Chinese cities

21 June 2021

A secure quantum link has been created between two Chinese cities, allowing researchers to send entangled photons more than 500 kilometres using a relay hub in the middle that doesn't need to be trusted

Quantum memory crystals are a step towards a futuristic internet

2 June 2021

A secure quantum internet is one step closer thanks to a quantum memory made from a crystal that can store entangled photons

Frozen cloud of molecules acts as a single quantum object

28 April 2021

For the first time, researchers have created a frozen cloud of molecules that share the same quantum state, meaning it behaves as if it were a single molecule
