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 ...

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team has developed a method ...

The company said it is able to reduce error rates in its quantum computing capabilities by 1,000-fold thanks to four-dimensional geometric codes. Quantum Computing ...

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 ...

Quantum dynamics—the study of how particles behave and interact in a quantum system—has long fascinated physicists due to its puzzling and sometimes bizarre behaviors. Unlike classical systems, where ...
