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 ...

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve ...

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 ...

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 ...

Quantum computers, devices that can perform computations relying on the principles of quantum mechanics, are expected to outperform classical computers on some types of optimization and processing ...

After the applied mathematician Peter Shor, then at Bell Labs in New Jersey, showed that a quantum algorithm could, in theory ...

In a laboratory at Oxford University, scientists have achieved something that once seemed science fiction: they made two separate quantum computers work together as one. Instead of being connected by ...
