Arrays of coupled superconducting qubits natively emulate the dynamics of interacting particles according to the Bose–Hubbard model. However, many interesting condensed-matter phenomena emerge only in the presence of electromagnetic fields. A team of researchers in the US (MIT, MIT Lincoln Laboratory) emulated the dynamics of charged particles in an electromagnetic field using a superconducting quantum simulator. They produced a broadly adjustable synthetic magnetic vector potential by applying continuous modulation tones to all qubits. The synthetic vector potential obeyed the required properties of electromagnetism… read more. TECHNICAL ARTICLE
