Quantum computing uses the power of atoms to perform memory and processing tasks and remains a theoretical concept. However, it is widely believed that its creation is possible.
Most experts now agree that the creation of a quantum computer is simply a matter of engineering, and that the theoretical application will happen. Optimistic estimates for commercialization by the private sector vary between 5 and 15 years, while more conservative estimates by academics put it at 15-25 years.
The race to quantum supremacy
The drive to create the first quantum computer has been viewed as the new arms race. The milestone to reach is that of quantum supremacy, essentially the performance of computation that goes beyond the capability of the latest and best supercomputers in existence today. But this drive is underpinning another, more pressing race: quantum cybersecurity.
ABI Research forecasts that the first attack-capable quantum machines will make their market debut by 2030. Michela Menting, Research Director at ABI Research warns, “When they do, even the latest and best in class cybersecurity technologies will be vulnerable.”
The race to quantum supremacy is real: governmental R&D is accelerating the crystallization of the quantum computer, with more than $1.6 billion already invested globally. The potentially drastic repercussions on cybersecurity is equally real and has led to the focus on quantum-safe cryptography. Also known as post quantum cryptography, such research looks to the development of new cryptographic algorithms that could withstand breaking by quantum computers, ideally before such computers become commercially available. Standards agencies the world over, including the NIST and ETSI, are focusing their efforts on developing appropriate standards as time grows increasingly shorter.
Developing new cryptographic techniques
Beyond and ahead of quantum computers, the use of the theory has also aided in developing new cryptographic techniques, notably quantum key distribution (QKD). Considered as a type of quantum-safe cryptography, QKD will likely be commercialized before the advent of quantum computers, because it is achievable using current technologies such as lasers and fiber optics. In that sense, QKD is one of the first quantum theories to find real-world applications.
Heavy private sector investment is going into quantum R&D. Since 2012, VC funds have pumped over US$334 million into companies specializing in the space. Those standing out in the space include CipherQ, CryptaLabs, CryptoExperts, ID Quantique, ISARA, MagiQ Technologies, Post-Quantum Solutions, Qubitekk, QuintessenceLabs, QuNu Labs, and SecureRF.
“The transition to quantum resistant cryptography is bound to take time but enterprises should already start considering how to address this future security gap in in their risk assessments and pay attention to both standard developments and market solutions,” Menting concludes.
