A multinational team has cracked a long-standing barrier to reliable quantum computing by inventing an algorithm that lets ordinary computers faithfully mimic a fault-tolerant quantum circuit built on ...

For more than a decade, the world of digital currency has been built on a single foundation: the blockchain. This complex, code-based system of distributed ledgers was a revolutionary approach to ...

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 ...

One of the main issues in developing the machines is they often struggle with data errors. But IBM says its chips could make a difference. Technology giant IBM has reached a major milestone in its ...
