Barren plateaus are stretches of the quantum algorithm optimization landscape so unnervingly flat that gradient‑based methods ...

Los Alamos National Laboratory has led the world in trying to understand one of the most frustrating barriers that faces ...

Scientists have developed an exact approach to a key quantum error correction problem once believed to be unsolvable, and have shown that what appeared to be hardware-related errors may in fact be due ...

The computing giant's new quantum roadmap shows its plan to achieve one of the most important goals in all of quantum ...

Enhanced Optimisation: Quantum algorithms like the Quantum Approximate Optimisation Algorithm (QAOA) and Variational Quantum Eigensolver (VQE) show promise in optimising AI models. These ...

Physicists have made a striking leap toward solving one of science’s deepest riddles—what lies at the heart of a black hole. In a pioneering study published in PRX Quantum, a team led by Enrico ...
