Quantum 7, 1110 (2023). https://doi.org/10.22331/q-2023-09-11-1110 We present two quantum interior point methods for semidefinite optimization problems, building on recent advances in quantum linear system algorithms. The first scheme, more similar to a classical solution algorithm, […]
Quantum 7, 1109 (2023). https://doi.org/10.22331/q-2023-09-11-1109 In the lead up to fault tolerance, the utility of quantum computing will be determined by how adequately the effects of noise can be circumvented in quantum algorithms. Hybrid quantum-classical […]
In 1935, Albert Einstein and Erwin Schrödinger, two of the most prominent physicists of the day, got into a dispute over the nature of reality. Einstein had done the math and knew that the universe […]

Using laser light, researchers have developed the most robust method currently known to control individual qubits made of the chemical element barium. The ability to reliably control a qubit is an important achievement for realizing […]
Quantum computers, systems that perform computations by exploiting quantum mechanics phenomena, could help to efficiently tackle several complex tasks, including so-called combinatorial optimization problems. These are problems that entail identifying the optimal combination of variables […]
Research at Hokkaido University has revealed that elusive particles called neutrinos can interact with photons, the fundamental particles of light and other electromagnetic radiation, in ways not previously detected. The findings from Kenzo Ishikawa, Professor […]
