quantum algorithms:
In quantum computation the term “dynamic lifting” (mostly used in the Quipper-community, starting around Green et al (2013), p. 5) refers to the outcome of quantum measurement-results — which can be known only during runtime (ie. “dynamically”), due to the intrinsic stochastic nature of quantum physics — being turned into (ie. “lifted” back to) variables on which subsequent classical computation may be conditioned, which may then in turn control further quantum circuits, etc.:
Dynamic lifting is thought (eg. Rand (2018),p. 52) to be optional in cases like the quantum teleportation protocol but necessary for applications like
quantum error correction (e.g. Paler, Herr & Devitt (2019), §4.1), where error correction steps are conditioned on quantum measurement of syndrome qbits;
repeat-until-success computing, where a quantum circuit is re-run on its input data until a failure syndrome measurement indicates success.
There have been several (partial) proposals for the precise categorical semantics of this idea, see the references below. Another formalization, via monadic effects of potentiality modalities in dependent linear type theory, is discussed at quantum circuits via dependent linear types (CQTS 2022, see there).
The general but informal idea of quantum computation with classical control that may itself be conditioned on quantum measurement results (see also at Quantum Computation – Classical control and quantum data) may be argued to be implicit already in Knill (1996).
Explicit discussion includes:
The term “dynamic lifting” is mainly used in discussion of the quantum programming language Quipper. Its first (brief) appearance might be that in:

Proposals for categorical semantics of “dynamic lifting”, mostly following along the lines of some dependent linear type theory:
