Quantum computing has made significant advancements in recent years, with improvements in qubit count, coherence time, and gate fidelity. However, according to Forrester’s 2024 Quantum Computing Trends report, quantum systems have not yet reached a point where they can outperform classical computers in practical applications.
While there has been substantial progress in the field of quantum computing, Forrester analysts believe that a true breakthrough has yet to occur. Despite this, the Global Risk Institute estimates that by 2030, there is a significant probability that quantum computers will be able to crack commonly used cryptographic methods.
Experts predict that widespread applications of quantum computing are still at least a decade away, leading to discussions about Post-Quantum Computing (PQC). This concept focuses on developing new cryptographic algorithms that are secure against quantum attacks, ensuring data protection in a quantum-enabled world.
Amdocs’ Avishai Sharlin believes that PQC will see significant advancements in 2025 as businesses and governments begin adopting Quantum-Safe encryption to secure their data.
In August 2024, the National Institute of Standards and Technology (NIST) finalized the first set of encryption algorithms designed to withstand potential threats from quantum computers. These standards represent a crucial step in safeguarding digital communications and data against the capabilities of quantum computing.
Transitioning to post-quantum computing and integrating quantum-safe encryption pose challenges for organizations. It requires a clear understanding of the threat posed by quantum computing, mapping of applications, and updating software to support PQC algorithms.
Sharlin emphasizes the importance of building relevant skills, preparing for the adoption of PQC solutions, and understanding the implications of quantum computing on cybersecurity. He notes that heavy lifting enterprises will be prioritized in adopting PQC due to the significant risks associated with outdated encryption technologies.
As the prevalence of quantum computing and associated cyber threats grows, post-quantum computing will play a crucial role in securing data. However, cybersecurity expertise will remain essential in combating evolving threats in the digital landscape.
