An *implementation* is a concrete physical realization of a theoretical concept. The [[Hamiltonian Operator|Hamiltonian]] of a quantum system can, for example, be *implemented* with the help of [[Platform - Cold Atoms|atoms]], or with [[Platform - Ions|trapped ions]], [[Platform - Superconducting Circuits|superconducting qubits]], etc. Sometimes an *implementation* is referred to as a [[Platforms|platform]]. Different implementations have their (often application-specific) advantages and disadvantages. If a physical model describes a system with long-range interactions, the implementation should reflect this. Other abstract concepts, such as [[Quantum Algorithm|quantum algorithms]], are also implemented in practice with the help of [[Platforms|specific implementations]]. In classical computer science, the concept of [[Bit|bits]] is embodied in various realizations. [[Bit|Bits]] can be realized with the help of magnetic domains on a hard drive or with the help of electric current in cables. >[!read]- Further Reading >[[Platforms]] >[!ref]- References
