Quantum computing with qiskit; what is a 'promise'?
In the context of quantum computing with Qiskit, a "promise" typically refers to a condition or constraint that is guaranteed to be true for a given problem. This concept is often used in the context of quantum algorithms, particularly in promise problems.
A promise problem is a type of computational problem where the input is guaranteed to satisfy a certain condition (the promise). This allows the algorithm to focus on solving the problem under the assumption that the input meets the specified criteria. For example, Grover's algorithm is designed to search an unsorted database, but it assumes that there is exactly one item that matches the search criteria. This assumption is the "promise" of the problem.
In summary, a promise in quantum computing is a predefined condition that the input to a problem must satisfy, allowing the algorithm to operate under specific constraints and potentially achieve better performance1
If you have any specific questions about how promises are used in quantum algorithms or need further clarification, feel free to ask!

Checked in with the Coding with Qiskit site and the Derek Wang series. I am up to
Episode 5, so will be working throught that in the next few days. It is what I was hoping
for: how to create dynamic circuits that use classical code to link quantum operations.
