### Magic states offer surprisingly low error rates for quantum computing

(Phys.org)—Quantum computers hold a special allure, as they offer a way to harness quantum phenomena and put it to use to do things that are impossible for ordinary computers. But as powerful as quantum computers could ...

### Electrical control of quantum bits in silicon paves the way to large quantum computers

A UNSW-led research team has encoded quantum information in silicon using simple electrical pulses for the first time, bringing the construction of affordable large-scale quantum computers one step closer to reality.

### Team tightens bounds on quantum information 'speed limit'

If you're designing a new computer, you want it to solve problems as fast as possible. Just how fast is possible is an open question when it comes to quantum computers, but physicists at the National Institute of Standards ...

### Quantum compute this—Mathematicians build code to take on toughest of cyber attacks

Washington State University mathematicians have designed an encryption code capable of fending off the phenomenal hacking power of a quantum computer.

### Quantum teleportation on a chip

The core circuits of quantum teleportation, which generate and detect quantum entanglement, have been successfully integrated into a photonic chip by an international team of scientists from the universities of Bristol, Tokyo, ...

### Researchers develop the first-ever quantum device that detects and corrects its own errors

When scientists develop a full quantum computer, the world of computing will undergo a revolution of sophistication, speed and energy efficiency that will make even our beefiest conventional machines seem like Stone Age clunkers ...

### 'Fibonacci quasiparticle' could form basis of future quantum computers

(Phys.org)—Topological quantum computing (TQC) is a newer type of quantum computing that uses "braids" of particle tracks, rather than actual particles such as ions and electrons, as the qubits to implement computations. ...

### Getting the measure of matter

Peter Rohde and his collaborators develop big ideas – and a measure of corny humour – using photons, the smallest possible units of light. (Did you hear about the photon that walked into a hotel and the clerk asked for ...

### New largest number factored on a quantum device is 56,153

(Phys.org)—Researchers have set a new record for the quantum factorization of the largest number to date, 56,153, smashing the previous record of 143 that was set in 2012. They have shown that the exact same room-temperature ...
