Watch a movie backwards and you’ll likely get confused – but a quantum computer wouldn’t. That’s the conclusion of researcher Mile Gu at the Centre for Quantum Technologies (CQT) at the National University of Singapore and Nanyang Technological University and collaborators. In research published 18 July in Physical Review X, the international team show that a…
Reversing Cause and Effect is no Trouble for Quantum Computers
Watch a movie backwards and you’ll likely get confused – but a quantum computer wouldn’t. That’s the conclusion of researcher Mile Gu at the Centre for Quantum Technologies (CQT) at the National University of Singapore and Nanyang Technological University and collaborators. In research published 18 July in Physical Review X, the international team show that a…
Want More Efficient Simulators? Store Time in a Quantum Superposition
Quantum Algorithm Could Help AI Think Faster
Retrospective Test for Quantum Computers can Build Trust
Tech companies are racing to make quantum computers available to customers. A new scheme from researchers in Singapore and Japan could help customers establish trust in what they get if they buy time on such machines – and protect companies from dishonest customers. Quantum computers have the potential to solve problems that are beyond the…
Butterfly Emerges from Quantum Simulation
Quantum simulators, which are special-purpose quantum computers, will help researchers identify materials with new and useful properties. This enticing future has just taken a step forward thanks to a collaboration between Google and researchers at universities in California, Singapore and Greece. The international team used photons in Google’s quantum chip to simulate the surprising and…
Light, Meet Atom
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what you’re looking at. Some photons reflect off, reaching your eyes. Others get absorbed. The main decider of which happens is the photon’s energy — its color. But…
Nanosatellite Tests Particles for Global Quantum Network
You can’t sign up for the quantum Internet just yet, but researchers have reported a major experimental milestone towards building a global quantum network — and it’s happening in space. With a network that carries information in the quantum properties of single particles, you can create secure keys for secret messaging and potentially connect powerful…
