However, quantum annealing functions more like a traditional anneal, which is a process for repeatedly heating and cooling metal slowly enough to minimize its internal stress so it becomes stronger. Gate-based quantum computer. An annealing process that experiences no interference from outside energy sources and evolves the Hamiltonian slowly enough is called an adiabatic process, and this is where the name adiabatic quantum computing comes from.

There is universality with gate-based systems that cannot be replicated with QA systems which have specific use cases.

1. Since Quantum Annealing is extremely powerful for optimization it is limited in scope. Quantum logic gates are represented by unitary matrices.A gate which acts on qubits is represented by a unitary matrix, and the set of all such gates with the group operation of matrix multiplication is the symmetry group U(2 n).The quantum states that the gates act upon are unit vectors in complex dimensions, with the complex Euclidean norm (the 2-norm).

for this purpose is the quantum annealing algorithm. An optimization problem is when one searches for the best configuration out of many possible combinations. However, when a universal Quantum Computer based on gates arrives, it will have a wider scope including optimization as well.
