To progress in the characterization of noise for quantum computers, gate set tomography (GST) has emerged as a self-consistent protocol that accurately estimates noisy gates, state preparations, and ...

Simulating the non-equilibrium dynamics of quantum field theories in nature is generally intractable with classical methods, but is a promising application for quantum computers. Unfortunately, ...

Conventional quantum algorithms are not feasible for solving combinatorial optimization problems (COPs) with constraints in the operation time of quantum computers. To address this issue, researchers ...

Quantum advantage refers to the point at which a quantum computer solves a clearly defined task faster or more efficiently than any classical computer—or makes it solvable in the first place. For many ...

Every optimization algorithm needs an honest referee. For combinatorial problems written as Ising spin glasses or quadratic ...

Q-day is shorthand for the point when a cryptographically relevant quantum computer can break widely used public-key ...

In a milestone that brings quantum computing tangibly closer to large-scale practical use, scientists at Oxford University Physics have demonstrated the first instance of distributed quantum computing ...

Quantum is quickly advancing toward commercial utility, bringing revolutionary benefits to numerous industries and solving intractable problems. Quantum computing's potential stems from its very ...

When a quantum computer processes data, it must translate it into understandable quantum data. Algorithms that carry out this 'quantum compilation' typically optimize one target at a time. However, a ...

French companies C12 and Thales have introduced QuantumTrack, a hybrid quantum-classical system for real-time radar tracking ...

Quantum computing exists beyond the realm of science fiction. Technology is now integrating with artificial intelligence to transform machine learning capabilities, adaptation and reasoning abilities.

Researchers said it was the first time a quantum computer “posed a real and substantial threat” to encryption, but multiple limitations still hamper a full-scale hack. Chinese researchers using a ...
