IQM Quantum Computers has developed a new quantum error-correcting code that it says can ...

A research team has created a quantum logic gate that uses fewer qubits by encoding them with the powerful GKP error-correction code. By entangling quantum vibrations inside a single atom, they ...

Quantum computing may one day outperform classical machines in solving certain complex problems, but when and how this “quantum advantage” emerges has remained unclear. Now, researchers from Kyoto ...

Quantum computers are computing systems that process information leveraging quantum mechanical effects. These computers rely on qubits (i.e., the quantum equivalent of bits), which can store ...

To build a large-scale quantum computer that works, scientists and engineers need to overcome the spontaneous errors that quantum bits, or qubits, create as they operate. Scientists encode these ...

Classical computing has operated as the fundamental power behind our digital world for many decades. Modern civilization relies on classical systems to operate smartphones and global financial ...

Algorithms called phantom codes could help quantum computers run complex programs without errors, overcoming a big hurdle for making the technology more broadly useful. Many popular error-correcting ...
