Quantum computer works with more than zero and one

We all learn from early on that computers work with zeros and ones, also known as binary information. This approach has been so successful that computers now power everything from coffee machines to self-driving cars and ...

Can entangled qubits be used to probe black holes? (Update)

Physicists have used a seven-qubit quantum computer to simulate the scrambling of information inside a black hole, heralding a future in which entangled quantum bits might be used to probe the mysterious interiors of these ...

Can we peek at Schrodinger's cat without disturbing it?

Quantum physics is difficult and explaining it even more so. Associate Professor Holger F. Hofmann from Hiroshima University and Kartik Patekar from the Indian Institute of Technology Bombay have tried to solve one of the ...

Transferring quantum information using sound

Quantum physics has led to new types of sensors, secure data transmission methods and researchers are working toward computers. However, the main obstacle is finding the right way to couple and precisely control a sufficient ...

A quantum radar that outperforms classical radar by 20%

Quantum technologies, a wide range of devices that operate by leveraging the principles of quantum mechanics, could significantly outperform classical devices on some tasks. Physicists and engineers worldwide have thus been ...

Less is more for Maxwell's Demon in quantum heat engines

Over 150 years after the famous Scottish scientist James Clerk Maxwell first introduced the idea, the concept of Maxwell's demon continues to perplex physicists and information scientists. The demon he dreamed up in a thought ...

Quantum computers offer another look at classic physics concepts

"Think what we can do if we teach a quantum computer to do statistical mechanics," posed Michael McGuigan, a computational scientist with the Computational Science Initiative at the U.S. Department of Energy's Brookhaven ...
