Special Issue Information

Dear Colleagues,

Quantum computers (QCs) base their computing functionalities on the phenomena and properties of quantum mechanics (QM) theories, such as superposition and entanglement. When super-powerful quantum computing devices, with large numbers of qubits, become reality, it will shake our world! A large variety of applications will appear, ranging from cryptography to chemistry, medicine and pharmacology. Additionally, powerful, quantum machine learning algorithms will be proposed and applied to solve complex, heterogeneous and multi-dimensional data, and the majority of scientific fields will flourish. In particular, within days or months QCs will propose solutions for vaccines and drugs, which currently take years to discover and test. Additionally, cryptography and current cryptographic algorithms will no longer have power. Codes and passwords will break within seconds. In addition, chemical, healthcare and drug development industries, security and so on, will take advantage of the new and revolutionary computing era. Therefore, new meta-quantum cryptographic algorithms will have to be devised and take the lead. However, the problem of QC reliability remains, especially as qubit number and circuit size escalate.

In this Special Issue, research works as well as practical applications are of interest. We invite authors from universities and research centers as well as independent researchers to contribute. The Special Issue will mainly focus on high-quality research works focused on, but not limited to, one or more of the following topics:

  • Quantum computing research and applications on chemistry and material science, blockchain and cybersecurity, logistics, healthcare, agriculture, finance, and so on;
  • Quantum machine learning (algorithms, applications, and techniques);
  • Quantum processing units (QPUs) and error correction;
  • Quantum drug development;
  • Parallel computations on quantum computing devices;
  • Algorithms and quantum computing in the NISQ (noisy intermediate-scale quantum) era;
  • Quantum key distribution;
  • Post-quantum cryptography;
  • Quantum annealing and adiabatic quantum computing;
  • Quantum telecommunications;
  • Quantum networking and quantum internet;
  • Benchmarking quantum computing devices;
  • Quantum computing and optimization (i.e., modelling and simulation);
  • Quantum information theory (i.e., entropy, information channels);
  • Classical shadows;
  • Future trends of quantum computing;
  • Quantum applications (i.e., medical, defense, energy system, smart grid etc.).

An available trick to mitigate the interference of environmental noise in quantum communications is to modulate signals with time-polarization multiplexing. Conversely, due to effects of the atmospheric turbulence in free space, the polarization of signals fluctuates randomly, resulting in feasible information leakage when direct polarization demultiplexing is carried out at the receiver, drowning out the noise-contained signals. For enhancing the practical security of the continuous-variable quantum key distribution (CVQKD), we propose a machine learning (ML) approach for optimization of the dynamic polarization control (DPC) of signals transmitted through atmospheric turbulence. An optimal DPC scheme can be adaptively adjusted with ML algorithms, which is based on the received signals at the receiver for solving the loophole problem of information leakage since it provides an accurate response to the polarization changes regarding the anamorphic signals. The performance of the CVQKD system can be increased in terms of secret key rates and maximal transmission distance as well. Numerical simulation shows the positive effect of the ML-based DPC while taking into account the secret key rate of the CVQKD system. The ML-based DPC effectively reduces the feasibility of information leakage and hence results in an increased secret key rate of the practical CVQKD system. Full article

The rapid development of quantum computing devices promises powerful machines with the potential to confront a variety of problems that conventional computers cannot. Therefore, quantum computers generate new threats at unprecedented speed and scale and specifically pose an enormous threat to encryption. Lattice-based cryptography is regarded as the rival to a quantum computer attack and the future of post-quantum cryptography. So, cryptographic protocols based on lattices have a variety of benefits, such as security, efficiency, lower energy consumption, and speed. In this work, we study the most well-known lattice-based cryptosystems while a systematic evaluation and comparison is also presented. Full article

The drug discovery process is a rigorous and time-consuming endeavor, typically requiring several years of extensive research and development. Although classical machine learning (ML) has proven successful in this field, its computational demands in terms of speed and resources are significant. In recent years, researchers have sought to explore the potential benefits of quantum computing (QC) in the context of machine learning (ML), leading to the emergence of quantum machine learning (QML) as a distinct research field. The objective of the current study is twofold: first, to present a review of the proposed QML algorithms for application in the drug discovery pipeline, and second, to compare QML algorithms with their classical and hybrid counterparts in terms of their efficiency. A query-based search of various databases took place, and five different categories of algorithms were identified in which QML was implemented. The majority of QML applications in drug discovery are primarily focused on the initial stages of the drug discovery pipeline, particularly with regard to the identification of novel drug-like molecules. Comparison results revealed that QML algorithms are strong rivals to the classical ones, and a hybrid solution is the recommended approach at present. Full article
