ChangeAnsatzes
ChangeAnsatzes is a term used in quantum computing and numerical methods to describe strategies that modify the assumed form of the solution, called the ansatz, during computation. In variational quantum algorithms, the ansatz is a parameterized quantum circuit designed to approximate a target state. ChangeAnsatzes refers to adaptive or dynamic approaches in which the structure of the ansatz is expanded, contracted, or reconfigured during optimization to balance expressivity and trainability.
Common implementations include adaptive ansatz construction, where operators are added to the circuit in response to
Benefits of ChangeAnsatzes include improved accuracy for a given resource budget, better mitigation of barren plateaus,
Applications are prominent in quantum chemistry and materials science, where dynamically adapting the ansatz can lead
