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]
