Key to the researchers’ discovery were rescued particles they dubbed “neglectons,” a name that reflects both their overlooked status and their newfound importance. (Image generated using MidJourney)
Mathematicians use ‘neglected’ particles that could rescue quantum computing
With one overlooked ingredient, researchers show how to turn a promising quantum system into a universal computer.
Quantum computers have the potential to solve problems far beyond the reach of today’s fastest supercomputers. But today’s machines are notoriously fragile. The quantum bits, or “qubits,” that store and process information are easily disrupted by their environment, leading to errors that quickly accumulate.
One of the most promising approaches to overcoming this challenge is topological quantum computing, which aims to protect quantum information by encoding it in the geometric properties of exotic particles called anyons. These particles, predicted to exist in certain two-dimensional materials, are expected to be far more resistant to noise and interference than conventional qubits.
