Quantum technologies have three primary applications: computing, communication and sensing. Computing still attracts most of the research and development (R&D) effort and investor money. However, pushed by quantum computing developments, the other two are also starting to attract more attention: quantum networking will be necessary to interconnect quantum computers, and new applications will require ultra-sensitive sensors based on quantum effects.

Eric Mounier, Ph.D., director of market research at Yole Intelligence said, “As quantum computers become readily available, they will be able to break the current integrity keys used for data exchange. This creates a direct connection to quantum cryptography, and post-quantum approaches are being developed to prevent future hacking by quantum computers (communication, bitcoins, cryptocurrency, etc., could also be compromised by quantum computers).”


In this context, Yole Intelligence releases its brand-new emerging technology report, Quantum Technologies 2023. With this report, the company, part of Yole Group, gives an overview of the quantum technologies for computing (hardware and software), networking and sensing applications.

The involvement of semiconductor players, including GlobalFoundries, TSMC, X-FAB, Intel, photonics with Ligentec, and equipment makers (for example, Keysight, Formfactor, Oxford Instruments, AMAT) is setting up a robust technological base for future quantum technologies: spin QD is, of course, also of interest, as it leverages Si CMOS technology.

But partnerships are still critical since only relatively few companies can pursue different R&D approaches simultaneously. Infineon Technologies is quite the exception, with R&D on three different technological qubit techniques: superconducting, trapped ions and spin.

The trend today is to have a “full stack approach” from the quantum chips up to the computer and software/service level. However, as this approach requires significant R&D resources, people, budget and effort, not all players can do it.
