Google’s latest quantum chip, Willow, recently demonstrated remarkable progress in this area. The more qubits Google used in Willow, the more it reduced the errors. This achievement marks a ...
However, in many cases, quantum simulators can be used instead: one quantum system (for example, a cloud of ultracold atoms) is studied in order to learn something about another system that looks ...
The optical nature of exciton-polaritons enables new types of devices that leverage coherent quantum effects. Here the authors demonstrate a ring-shaped Josephson junction on a solid-state exciton ...
