Scientists built a quantum gate linking four-state photons, showing complex quantum tasks can be done with fewer steps using qudits.

Researchers have developed a new protocol for characterizing quantum gate errors, paving the way toward more reliable quantum simulations and fault-tolerant quantum computing. Researchers have ...

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 ...

Google has issued a blog in which the company claims that its “Willow” quantum chip has achieved the first-ever demonstration of verifiable quantum advantage. “This milestone is a critical step toward ...

Lead author and PhD student Vassili Matsos looking at the Paul trap quantum computing device in the Quantum Control Laboratory at the University of Sydney. To build a large-scale quantum computer that ...
