In the context of quantum mechanics and information, "magic" is a key property of quantum states that describes the extent to which they deviate from so-called stabilizer states. Stabilizer states are ...

Quantum computers have performed the full slate of tricks needed for robust computation. And it all came down to a little magic. In a pair of papers submitted June 17 at arXiv.org, researchers ...

Quantum computers have the potential to outperform conventional computers on some tasks, including complex optimization problems. However, quantum computers are also vulnerable to noise, which can ...

For all its promise, quantum computing suffers from its own fragility. Even the slightest disturbance can scramble the information encoded in a quantum bit. UC Santa Barbara physics professor Andrea ...

Luke Coffman, a senior double majoring in physics and math, has been recognized for his outstanding research with a Stephen Halley White Undergraduate Research Award. The award is one of the top ...

Scientists have taken a major step toward ultra-secure quantum communication by demonstrating a remarkably stable quantum encryption system that worked across more than 120 kilometers of optical fiber ...

In a world-first, scientists used precisely controlled optical traps, known as "magic-wavelength optical tweezers," to create ...

We have been under the assumption that the encryption that protects our bank accounts, patient records, and government ...
