Abstract

The Deutsch-Jozsa quantum algortihm is demonstrated experimentally for three-qubit functions using pure cotherent superpositions (wave packets) of molecular (Li2) rovibrational eigenstates. An oracle encodes the function into a phase-tailored femtosecond laser pulse that transforms the molecule into a corresponding superposition. The function's character (constant/balanced) is evaluated by probing the overall superposition through its projection on an ionic final state. It is done by ionizing the molecule using a second femtosecond pulse at a specific time delay. The present experimental implementation is carried out in the framework of coherent computation using quantum molecular elements, distinguishable from quantum computation based on entanglement.
