The quantum computing and communications market size is expected to see exponential growth in the next few years. It will grow to $6.93 billion in 2030 at a compound annual growth rate (CAGR) of 35.2%. The growth in the forecast period can be attributed to rising adoption of quantum computing as a service, increasing deployment of quantum communication networks, growing demand for quantum-secured communication solutions, expanding development of fault-tolerant quantum systems, and increasing investments in scalable quantum technologies. Major trends in the forecast period include increasing development of fault-tolerant quantum computing architectures, advancements in quantum communication network infrastructure, growing integration of quantum computing with communication capabilities, development of scalable quantum processors and quantum repeaters, and increasing adoption of quantum key distribution for secure communications.

The increasing digital transformation across industries is expected to propel the growth of the quantum computing and communications market going forward. Digital transformation across industries refers to the adoption of advanced digital technologies to modernize business operations, optimize processes, and enhance overall organizational performance across diverse sectors. Digital transformation across industries is increasing due to the growing need for operational efficiency, as organizations adopt digital technologies to automate processes, reduce costs, improve productivity, and respond more rapidly to changing market demands. Quantum computing and communications support digital transformation across industries by enabling significantly faster data processing, secure communication, and advanced optimization capabilities, helping organizations address complex problems and enhance operational efficiency. For instance, in November 2023, according to the Central Digital and Data Office, a UK-based government agency responsible for digital transformation across UK government departments, the overall size of the Government Digital and Data profession grew by 19% from April 2022 to April 2023. Therefore, the increasing digital transformation across industries is driving the growth of the quantum computing and communications market.

Leading companies operating in the quantum computing and communications market are focusing on developing innovative solutions such as error-corrected quantum computer platforms to accelerate fault-tolerant quantum computing, advance quantum error correction research, and improve system scalability and performance. Error-corrected quantum computer platforms refer to quantum computing systems designed with integrated quantum error correction technologies that detect and correct qubit errors, enabling more reliable and scalable quantum computations. For example, in November 2025, IQM Quantum Computers, a Finland-based quantum computing technology company, launched IQM Halocene, designed to support quantum error correction research through an open and modular on-premises quantum computing platform. It offers benefits such as advanced error correction functionality, an open and transparent modular error correction stack, and support for scalable logical qubit development with high-fidelity quantum processing. The launch aims to help customers accelerate quantum error correction research and develop fault-tolerant quantum computing capabilities while supporting the advancement of next-generation quantum computing technologies.
