In the world of quantum computing, the Hilbert space dimension—the measure of the number of quantum states that a quantum computer can access—is a prized possession. Having a larger Hilbert space ...

Quantum computing is still in its infancy, easily beaten by traditional computers. One of the biggest challenges? The fact that quantum bits — qubits — are much more fragile than the bits in silicon ...

Mistakes happen — especially in quantum computers. The fragile quantum bits, or qubits, that make up the machines are notoriously error-prone, but now scientists have shown that they can fix the flubs ...

Steve Brierley argues that quantum computers must implement comprehensive error-correction techniques before they can become fully useful to society Exploiting their advantage Quantum computers will ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. In a paper published in Nature this week, Google’s Quantum AI ...

Error-corrected magic: Clifford circuits attain universality – that is, the ability to compute any function that quantum theory permits – upon injection of special states called magic states.

Astronaut John Glenn was wary about trusting a computer. It was 1962, early in the computer age, and a room-sized machine had calculated the flight path for his upcoming orbit of Earth — the first for ...

When running a server, especially one with mission-critical applications, it’s common practice to use error-correcting code (ECC) memory. As the name suggests, it uses an error-correcting algorithm to ...

As memory bit cells of any type become smaller, bit error rates increase due to lower margins and process variation. This can be dealt with using error correction to ...
