Simulating quantum dynamical phenomena using classical oscillators*

Classical oscillators are ubiquitous in nature. With some modifications, they provide
analogues of systems from other fields of physics. An important example here is a basic system of quantum
mechanics and quantum technologies, a two-level system, or qubit. A qubit is described by its tuned energy
levels. Being driven, such system experiences resonant transitions, which is important for both system
characterization and control. However, in a number of works in different contexts, it was argued that diverse
classical systems can behave like qubits. Such systems include mechanical, opto-mechanical, electrical, and
optical realizations. A quantum system can be driven by either sinusoidal, rectangular or noisy signals. In the
literature, these regimes are referred to as Landau-Zener-Stückelberg-Majorana interferometry, latching
modulation, and motional averaging, respectively.[1]
