Quantum Information Processing Using Molecular Nanomagnets As Qubits

摘要

The idea that the superposition of quantum states could be utilized as a way of performing computation seems, at least on the surface, almost self-contradictory. However in 1994 Shor proposed an algorithm that would allow a quantum computer to factorize numbers much faster than a classical computer, and, shortly afterwards, Grover proposed an algorithm that would lead to much faster database searching with a quantum computer. As a result of these proposals much effort has been expended on finding physical systems that could be used in quantum information processing (QIP). One of the most promising systems—and one where chemists can make a very significant contribution through the synthesis of appropriate molecules—involves using molecular nanomagnets.
