Abstract
One of the most common problems in cybersecurity is related to the fraudulent activities that are performed in various settings and predominantly through the Internet. Securing online card transactions is a tough nut to crack for the banking sector, for which fraud detection is an essential measure. Fraud detection problems involve huge datasets and require fast and efficient algorithms. In this paper, we report on the use of a quantum machine learning algorithm for dealing with this problem and present the results of experimenting on a case study. By enhancing statistical models with the computational power of quantum computing, quantum machine learning promises great advantages for cybersecurity.

Notes
- 1.
For the purposes of this paper, it is sufficient to restrict ourselves to the finite-dimensional case where bounded linear operators can always be represented as matrices.
- 2.
The security of RSA and Diffie-Hellman cannot be demonstrated anymore with the prospective use of a quantum computer, since efficient quantum algorithms exist for factorization and for computing the discrete logarithm.
- 3.
The quantum computer currently available to the public is a very limited 16-qubit device, which is much too primitive (in terms of both stability and error tolerance) for practical problems.
