This paper describes the process of creating and using a quantum computing environment. It also discusses the manner in which first quantum experiments using mathematical models, simulators or commercially available quantum computers may be conducted. In addition, it explains how the available quantum algorithms may be understood and applied. Finally, the role of real-time systems and their control...
The aim of the paper is to show how graduated engineering students in classical ICT view practically the advent of the QIT. The students do their theses in El.Eng. and ICT and were asked how to implement now or in the future the QIT in their current or future work. Most of them have strictly defined research topics and in some cases the realization stage is advanced. Thus, most of the potential QIT...
Ion trap quantum computing (QC) is a promising technology with the potential to revolutionize many fields. However, there are still many challenges that need to be overcome before ion trap quantum computers become a reality. These challenges include scaling up the number of qubits, improving the co herence time of qubits, and developing new algorithms and software. Despite these challenges, ion trap...
Quantum integrated photonics (QIP) is one of the technological and system options for building quantum networks and compu ters. The carrier of multilateral, multidimensional quantum infor mation, in the state of coherent superposition and entanglement/ hyper-entanglement, is a single, most often heralded, or deter ministic photon or a cluster of photons. The material substrates for the operation of...
Quantum computers have emerged as a candidate for a trans formative technology with the potential to revolutionise va rious fields, from cryptography to drug discovery. Among the different types of quantum computers, ion trap-based systems have garnered significant attention due to their long coherence times and high-fidelity operations. In this article, we would like to scratch the surface of the...

Laser beam intensity stabilisation is an essential process in most quantum applications. Laser light intensity is a critical parameter in many quantum experiments, such as quantum computing, quantum communication, and quantum metrology. Even small fluctuations in laser intensity can lead to errors in the results of these experiments. This paper presents robust laser beam intensity stabilization methods...
The practical implementation of algorithms on a quantum computer requires creating and stabilising qubits and their appropriate entanglement. Currently, one systemic solution is to create entangled qubits in ion traps. The structure of the Quantum Computer Unit based on the Ca40 blade ion trap of up to 100 ions, supported by integrated optical, control and reading systems, will be discussed. These...
The report presents a thorough examination of quantum suprema cy and its far-reaching implications. Quantum computing, a cut ting-edge field, possesses the potential to reshape industries due to its unique quantum mechanical properties. Quantum suprema cy, wherein a quantum computer surpasses classical computers in specific tasks, has been achieved through ground-breaking experiments. While this marks...
Quantum computing is a rapidly developing field with the poten tial to revolutionise many aspects of technology, including the military. Quantum computers can solve specific problems much faster than classical computers, which could be used to develop new weapons systems, improve military communications, and secure military networks. However, there are also challenges to developing and using qu antum...
The article is a sort of advanced publication workshop prepared by a group of M.Sc. students in ICT participating in the course on QIT. The idea behind the publishing exercise is to try to link, if possible, individual own work just under realization for the thesis with new unique possibilities offered by the QIT. Each chapter is written by a single author defining concisely her/his research interest...
In this article we present a procedure that allows to synthesize optimal circuit representing any reversible function within reasonable size limits. The procedure allows to choose either the NCT or the MCT gate set and specify any number of ancillary qubits to be used in the circuit. We will explore efficacy of this procedure by synthesizing various sources of nonlinearity used in contemporary symmetric...
This article discusses four fields of study with the potential to revolutionize our understanding and interaction with biological systems: quantum biophotonics, molecular and supramolecular bioelectronics, quantum-based approaches in gaming, and nano-biophotonics. Quantum biophotonics uses photonics, biochemistry, biophysics, and quantum information technologies to study biological systems at the...
