Quantum Computing And Security Of
Information Systems

Abstract
Quantum computing (QC) is a fundamentally new interdisciplinary idea at the
interface of physics, mathematics and informatics. Today QC is still in its initial
stages in terms of its practical implementation due to difficulties related with
maintaining a high level of quantum coherency at the macroscopic level.
However, theoretical principles of QC are presently well understood and there is
a significant on-going progress towards actual prototypes of functioning QC.
Present protocols of secure electronic communication can be easily cracked by
QC. Thus, the advent of QC can make almost all existing systems of confidential
communications utterly unreliable. The present paper gives a non-specialist
overview of the principles of QC and discusses some of its possible applications,
and also addresses the above challenges concerning the reliability and security of
information and communication systems.
Keywords: quantum computing, quantum communication systems, secure
electronic communications, information generation systems, prime numbers,
quantum nonlocality.
1 Introduction
Security and confidentiality issues related to the generation, storage and
transmission of information were invariably important in the course of history in
many different ways. Before the advent of modern electronic information and
communication systems, information security largely consisted in physical
protection of paper-bound documents and communication channels. The science
and practical tools of cryptology – methods of coding and decoding of
information – constituted a significant facet of the security activity. All existing
methods of cryptology, some of which go back to ancient times, rely on the fact
