Tomografìa de las puertas cuanticas de las computadoras IBM

Abstract

Quantum tomography processes in order to characterise single- and multi-qubit quantum gates. Generally, quantum gates realised by quantum computers are not perfect. Therefore, characterisation by means of quantum tomography is necessary for the optimal design of quantum algorithms, therefore, the aim of the present research was "To develop tomography of quantum gates of IBM computers". The methodology implemented had a quantitative approach because the analysis of this type of data consists of statistically analysing the collected scores, e.g. through research questions and at the same time their development on quantum processors. The object of study is descriptive and the methodology to be applied to deduce a good or circumstance that is being presented. The work will be quasi-experimental because variables will be manipulated, and its inference will be hypothetical. The study will have a cross-sectional period because it will have a determined period in the development of quantum tomography of IBM computers. By means of this methodology, it was determined that using the results to be obtained, the error level of the quantum gates studied will be established. In the context it is concluded that from this reconstructed density matrix, relevant quantum information quantities can be calculated, such as the degree of entanglement and entropy, it will be demonstrated how non-orthogonal measurements allow the reconstruction of the state of the system if the measurements span the Hilbert space.
