The student of the Polytechnic University of Cartagena (UPCT) Sebastián García has put his grain of sand in the development of quantum supercomputing, an imminent technological revolution.

The student has formulated in his Final Degree Project in Industrial Technologies protocols to efficiently manipulate a quantum cubit or bit, basic element of processors based on quantum mechanics.

"Controlling a single cubit may seem little but we must bear in mind that the quantum processor created by Google, of which Nature published its results yesterday, only has 54 cubits and has proven to be far superior to the current supercomputers in certain types of calculations." , highlights Professor Javier Molina, who has directed the work with Juan Ignacio Mulero.

The student's work addresses the problem of the control of quantum systems that describes the famous paradox of Schrödinger's cat, who is both alive and dead in a box but if he stops being isolated he loses this overlap of states that defines his quantum nature

"The ulna are very delicate and their control requires extremely careful handling," says Molina.

The TFG thus describes control actions so that the ulna does not lose its quantum nature, with which it can simultaneously have the values ​​0 and 1 that the traditional binary bits contain.

"The superposition of states exponentially accelerates computational calculations and has great potential for the development of quantum cryptography," details the author of the work.

"Quantum control will be of great importance and I wanted to gain experience in this future technology," says the Cartagena student, who has started this course at the Master in Industrial Engineering at UPCT.

"The future is going through quantum technologies and we want a knowledge substrate in this research line at UPCT," said Molina, a member of the Quantum Many Body Systems and Quantum Technologies group and who has directed two other TFGs with Mulero in this field.

"The effort Sebastian has a great merit, for which we have requested Honor Registration, for training in quantum physics and putting the seeds for the development of quantum technologies in the Polytechnic," concludes Molina.
