According to Financial Times News, Google-Alphabet’s senior vice-president for research reveals that quantum computing is advancing more rapidly than public perception acknowledges, with recent breakthroughs including a 20-fold decrease in the estimated size of quantum computer needed to crack RSA-2048 encryption using Shor’s algorithm. The article highlights that Google’s quantum processor completed in minutes what would take today’s fastest supercomputers 10 septillion years, while researchers have identified at least 70 algorithms across mathematics, data science, and simulation that could outperform classical computers. Recent demonstrations include “below threshold” error correction and the first algorithm with verifiable quantum advantage on hardware, developed with University of California, Berkeley, showing potential for understanding molecular structure. The timeline suggests real-world applications could emerge within five years, even before large-scale error-corrected systems arrive, with the current stage compared to artificial intelligence in 2010 before major breakthroughs like AlphaFold and generative AI. This accelerated progress suggests we need to rethink our assumptions about quantum computing’s timeline.

The Quantum Continuum Is Already Here
What most observers miss about quantum computing is that we’re not waiting for a single breakthrough moment when everything changes overnight. The reality is more nuanced—we’re already in what I call the “quantum utility phase” where these systems provide value for specific, targeted problems even with their current limitations. The comparison to AI in 2010 is particularly insightful, as we’re at that inflection point where the technology transitions from academic curiosity to practical tool. Just as neural networks were solving real problems before ChatGPT made them mainstream, quantum systems are already advancing materials science and fundamental physics research in ways classical computers cannot match.
The Real Significance of Error Correction
The mention of “below threshold” error correction represents one of the most underappreciated developments in the field. For decades, quantum error correction was considered the fundamental barrier to practical quantum computing—the equivalent of trying to build a skyscraper on shifting sand. The demonstration that we can actually reduce errors below the threshold where they become manageable suggests we’ve solved the foundational physics problem. This doesn’t mean fault-tolerant quantum computers are around the corner, but it does mean we now understand the path forward. The engineering challenges remain immense, particularly around scaling and maintaining quantum coherence, but the theoretical roadblocks are falling faster than anticipated.
Near-Term Applications Beyond the Hype
While much public discussion focuses on breaking encryption—a legitimate concern given the recent advances with Shor’s algorithm—the more immediate applications lie in simulation and optimization. Quantum systems excel at modeling other quantum systems, which makes them uniquely suited for drug discovery, materials design, and catalyst development. Pharmaceutical companies are already experimenting with quantum algorithms to simulate protein folding and molecular interactions that would take classical supercomputers years to calculate. The growing library of quantum algorithms includes specialized approaches for financial modeling, supply chain optimization, and machine learning that could deliver practical advantages within the current hardware limitations.
Why Businesses Can’t Wait to Prepare
The most urgent message for industry leaders is that quantum readiness requires starting now, not when the technology matures. Companies in sectors like finance, pharmaceuticals, and materials science should be mapping their computational workflows to identify which problems are “quantum-ready”—meaning they’re both valuable to solve and amenable to quantum approaches. This involves building internal expertise, establishing relationships with quantum hardware and software providers, and potentially running pilot projects on existing quantum systems. The transition won’t be like flipping a switch; it will involve hybrid approaches where quantum and classical computers work together, with each handling the parts they do best.
The Coming Quantum Skills Gap
Perhaps the most immediate challenge is the talent shortage. We’re facing a massive skills gap in quantum-ready engineers, developers, and technicians. Unlike traditional computing where software developers can work abstracted from the underlying hardware, quantum programming requires understanding the physical principles of how quantum computers actually work. Educational institutions are scrambling to develop curricula, but the pipeline is years behind the accelerating technology. Professionals looking to future-proof their careers should consider how quantum principles might apply to their fields, whether through formal education or self-directed learning in quantum information science.
The Encryption Race Is Real
The accelerated timeline for breaking current encryption standards should concern every organization handling sensitive data. While the immediate risk might seem distant, the reality is that data encrypted today could be harvested and stored for decryption once sufficiently powerful quantum computers arrive. The migration to post-quantum cryptography standards is not a future problem—it’s a current imperative. Organizations with long-term data protection needs, particularly in government, finance, and healthcare, should already be testing and implementing quantum-resistant encryption methods. The transition will be complex and time-consuming, making early adoption crucial for security.
Realistic Expectations for the Next Decade
Looking ahead, we should expect quantum computing to follow a trajectory similar to other transformative technologies: initial overhyped expectations, followed by a period of disillusionment when the technology fails to deliver immediate miracles, and then gradual, steady integration into specific applications where it provides unique advantages. The companies that will benefit most are those taking a measured, strategic approach—investing in understanding the technology’s capabilities and limitations, building partnerships with research institutions, and identifying specific use cases rather than chasing quantum for quantum’s sake. The revolution won’t be televised because it’s already happening quietly in research labs and early-adopter industries.
