Transform of Quantum States Via Adiabatic Quantum Evolution

The success of quantum algorithms is to implement correctly quantum states transform,which is mainly achieved by suitable quantum operators.It is shown that the finding of a suitable quantum operator is a great challenge.Most of previous studies solve this problem by machine learning methods.However,these algorithms are different from the standard circuit model of quantum computation which characterizes as unitary quantum operations,thus they are difficult to be realized on quantum computers.It is shown that the transform of quantum states can be implemented by adiabatic quantum evolution,which is a kind of pure quantum effect and suitable well for physical implementation.The adiabatic theorem guarantees that the final state of the system would be the desired output.It is therefore a remarkable approach for quantum states transform in quantum computation and quantum communication.
