Quantum Information Technology: A Glimpse Into the Future

Executive Summary

The swiftly advancing landscape of 21st century information generation, transmission, and processing is quickly surpassing the capabilities of traditional electromagnetic systems. This calls for a progressive shift towards Quantum Information Technology (QIT). This technical whitepaper provides a broad overview, from the motivations for developing QIT to the roles of standardization associated with expected QIT products.
A myriad of factors are driving an increase in investments in QIT. These include, but are not limited to, projected domestic economic growth, benefits of quantum computing, the need for physically secure communication protocols, and the technological requirement for improved sensing devices. This paper also explores the evolving landscape of QIT through research, technological and market status.
As these technologies are still in developmental stages, this paper looks at both the near-term (0-10 years) and long-term (>10 years) potential of QIT.

Technical Overview

Quantum computing encompasses areas such as quantum hardware, quantum error correction, quantum algorithms, and quantum software. Quantum communications involve technologies for transmission/reception elements for quantum cryptographic key distribution. Quantum sensing includes research into quantum-based clocks, magnetic-field sensors, high-energy physics, inertial sensors, single photonic elements, and quantum imaging. These technological domains are rapidly evolving, with some potential applications in fields like deciphering, drug research and development, quantum machine learning, and search engines.

System Architecture

Quantum computing research revolves around superconducting quantum computing, ion-trap quantum computing, optical quantum computing, semiconductor quantum dots systems, quantum software, and quantum simulators. Quantum communication research primarily focuses on Quantum Key Distribution (QKD) technologies. Quantum sensing research is currently centered on prototyping of photon sensors, atomic clocks for timing and network synchronisation, devices measuring frequency spectrum, and sensing based on quantum entanglement.

Implementation Details

Quantum computing use cases include quantum chemistry, quantum AI, quantum computing in the financial industry, quantum optimization, and quantum cloud computing. Quantum communication use cases include leased lines, virtual private networks, electric power communications, wireless communications, and more. Given the nascent stage of these technologies, it is crucial to anticipate potential challenges and plan accordingly.
