Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...
Quantum computers are a little like librarians: both abhor noise. Compared with their classical counterparts, quantum computers are finicky and need a serene environment to perform their calculations ...
On Tuesday, Microsoft made a series of announcements related to its Azure Quantum Cloud service. Among them was a demonstration of logical operations using the largest number of error-corrected qubits ...
On grid: oscillator grid states have been used to do quantum error correction in a superconducting qubit. (Courtesy: Shutterstock/Dmitriy-Rybin) A practical ...
Written for you by our author Tejasri Gururaj, edited by Gaby Clark, and fact-checked and reviewed by Robert Egan —this article is the result of careful human work. We rely on readers like you to keep ...
Extended lifetime Quantum information is protected by encoding it in a more complicated system, such as the “GKP state”. (Courtesy: Volodymyr Sivak, Yale University) A team of researchers at Yale ...
