Effect of pure dephasing quantum noise in the quantum search algorithm: an undergraduate approach using Atos Quantum Assembly

Abstract

Quantum computing is tipped to lead the future of global technological progress. However, the obstacles related to quantum software development are an actual challenge to overcome. In particular, there is a discrepant lack of trained and skilled workforce to implement new quantum software on the recent quantum hardware. In this scenario, this work presents a didactic implementation of the quantum search algorithm in Atos Quantum Assembly Language (AQASM). In addition, we present the creation of a virtual quantum processor whose configurable architecture allows the analysis of induced quantum noise effects on the quantum algorithms. The codes are available throughout the manuscript so that readers, even those with little scientific computing experience, can replicate them and apply the methods discussed in this article to solve their own quantum computing projects. The presented results are consistent with theoretical predictions and demonstrate that AQASM and myQLM are powerful tools for teaching quantum computing and building, implementing, and simulating quantum hardware.
