“On bits and qubits” is the keynote lecture that belongs to the Digital Transformation Module of C1B3RWall Academy 2021, which brings us closer to the set of quantum phenomena applied to the field of cybersecurity. Mariano Caruso will give this lecture, he holds a degree in physics from the National University of La Plata (Buenos Aires), a master’s degree and a PhD from the University of Granada and is currently working in the area of research and development at the Fundacion I+D del Software Libre (FIDESOL).

If we seek to secure datasets using quantum technologies, we must first understand how information can be encoded in a quantum medium. The concept of the bit as a representation of fundamental information is well known, however, the concept of the qubit is not as well known. The aim is to highlight the huge contrast between these two concepts and then apply it to a secure key distribution protocol in the context of quantum cryptography.

The qubit represents a radical change in the notion of system state. Thanks to the existence of theories that explain quantum phenomena, we have access to all kinds of technologies.

– A bit takes only one value from the set 0, 1.

– A qubit takes some value from the set 0, 1.

Quantum systems are very sensitive to measurements. When a measurement or experiment is performed, the result will be that the final state of the qubit will be one or the other, north pole or south pole (measurement context).
