"Grover Algorithm implementation"


The power of a quantum algorithm compared to a classical one is of great interest but the realisation of such a functional system is an ambitious technologically goal. An example of this power was enlighted by L.K. Grover in 1996 when he developed an algorithm that use quantum parallelism to find an element in a database faster than all classical algorithm.
After an introduction to show the different system physicists can use to implement this algorithm, I will explain how to create a "quantum database" and how to find an element in this latter. Then I will focus on our experiment, a single molecular magnet spin based transistor. Recent measurements shown that we are able to read out and coherently manipulate the 4 states of a single nuclear spin exhibiting coherence time up to 300 µs.
Finally I will show that we can create a 4 elements database to implement Grover’s algorithm.
