Quantum computing is often discussed in terms of the security challenges it could create for existing encryption. But as the technology advances, enterprises are also beginning to explore another question: where could quantum computing improve the performance of artificial intelligence?
A recent CIO feature examines how quantum processing units could eventually complement the CPUs and GPUs that power today’s AI workloads. The article includes perspective from Arjun Kudinoor, quantum security advisor at Protegrity, on both the potential of quantum-enabled AI and the technical limitations organizations should keep in mind.
Where Quantum Computing Could Support AI
The CIO article explores the potential for hybrid computing environments that combine quantum processing units, CPUs, and GPUs. Rather than replacing traditional infrastructure, quantum systems could eventually be used for specific problems where classical computing encounters limitations in scale, time, or complexity.
For enterprise AI, that could mean using quantum computing for targeted portions of larger workloads while relying on traditional processors for the rest.
Protegrity Perspective: Quantum Will Not Replace GPUs Overnight
Arjun Kudinoor cautions against assuming that quantum computing will broadly replace the GPUs currently used for AI. GPUs remain well suited to the matrix operations that underpin many machine learning workloads, while quantum systems continue to face significant challenges around data loading, measurement, and error correction.
Arjun notes that quantum computers could eventually accelerate some AI workloads, but the benefits are more likely to apply to specific subroutines within larger workflows rather than serving as a wholesale replacement for existing AI infrastructure.
Security Remains Part of the Quantum Conversation
The article also addresses the cybersecurity implications of continued progress in quantum computing. Arjun points to the potential for sufficiently capable quantum systems to threaten widely used RSA- and ECC-based encryption.
That creates two parallel considerations for technology leaders: understanding where quantum computing may eventually create new opportunities for AI while also preparing for the security implications of advances in quantum capability.
A Practical Approach for CIOs
For CIOs and other IT leaders, the near-term priority is not to make large investments based on speculative timelines. It is to monitor developments, understand where quantum approaches may provide meaningful advantages, and evaluate claims against credible technical evidence.
Arjun recommends approaching the intersection of quantum computing and AI with cautious optimism, relying on trusted subject matter experts and avoiding hype-driven investment decisions.
As quantum technology matures, hybrid architectures may become increasingly relevant to enterprise AI. Organizations that build knowledge now will be better positioned to evaluate where quantum capabilities provide real value and where established computing approaches remain the better fit.
