IonQ (NYSE: IONQ), in collaboration with Hyundai Motor Company, has successfully demonstrated the accurate computation of atomic-level forces using the quantum-classical auxiliary-field quantum Monte Carlo (QC-AFQMC) algorithm. This demonstration represents a significant advancement in quantum […]
A team of international physicists has brought Bayes’ centuries-old probability rule into the quantum world. By applying the “principle of minimum change” — updating beliefs as little as possible while remaining consistent with new data […]
The 2025 Nobel Prize in physics honors three quantum physicists—John Clarke, Michel H. Devoret and John M. Martinis—for their study of quantum mechanics in a macroscopic electrical circuit. Click to rate this post! [Total: 0 […]
In 1939, upon arriving late to his statistics course at the University of California, Berkeley, George Dantzig — a first-year graduate student — copied two problems off the blackboard, thinking they were a homework assignment. […]
Quantum 9, 1884 (2025). https://doi.org/10.22331/q-2025-10-13-1884 We investigate quantum error correction protocols for neutral atoms quantum processors in the presence of atom loss. We complement the surface code with loss detection units (LDU) and analyze its […]
Quantum 9, 1883 (2025). https://doi.org/10.22331/q-2025-10-13-1883 In this work, we show that learning the output distributions of brickwork random quantum circuits is average-case hard in the statistical query model. This learning model is widely used as […]
Quantum 9, 1882 (2025). https://doi.org/10.22331/q-2025-10-13-1882 Despite its popularity, several empirical and theoretical studies suggest that the quantum approximate optimization algorithm (QAOA) has persistent issues in providing a substantial practical advantage. Numerical results for few qubits […]

Quantum 9, 1881 (2025). https://doi.org/10.22331/q-2025-10-13-1881 We propose efficient algorithms for classically simulating Gaussian unitaries and measurements applied to non-Gaussian initial states. The constructions are based on decomposing the non-Gaussian states into linear combinations of Gaussian […]
