Execution Model

The model which governs the execution of a program.

Classical

Quantum

Full Definition

The execution model defines the behavior between different components in the programming language, the interaction between the classical computer and the quantum computer (intermediate or non-intermediate) including scheduling. The execution model is enforced by the runtime environment. The program execution can be defined by operational semantics. In quantum computing three models have been defined 1:

  1. The QRAM Model
  2. The Restricted HQCC Model
  3. The Refined HQCC Model
