Abstract
Computers based quantum logic are believed to solve problems faster and more efficiently than computers based on classical boolean logic. However, a large-scale universal quantum computer with error correction may not be realized in near future. But we can ask the question: can we devise a specific problem that a quantum device can solve faster than current state of the art super computers? One such problem is the so called "Boson Sampling" problem introduced by Aaronson and Arkhipov. The problem is to generate random numbers according to same distribution as the output number configurations of photons in linear optics. It was shown that this is a very hard task for classical computers, but can be realized using quantum devices. However, realizing this in photonic systems is proving to be harder than ever because of various challenges in preparation and measurements. We propose and analyze an alternate platform to implement this problem, ultra-cold atoms trapped in one-dimensional optical lattices.
