5 min read“We’re on the precipice of quantum systems becoming a real utility within an overall advanced computing ecosystem,” says Bob Sorensen, chief analyst for quantum computing at Hyperion Research. But that precipice is still a few years out, and the path is littered with hype, hard physics problems, and a herd of hardware startups that will inevitably thin. In this episode of Catalyst, Shayle Kann and Sorensen cut through the breathless headlines to assess where quantum computing actually stands, what it can and cannot do today, and what the next few years will realistically bring.
Where quantum is today: noisy, intermediate, and not yet useful
Quantum computing’s origin story begins with physicist Richard Feynman in the 1980s, who observed that simulating quantum phenomena on a classical computer is “intractable”—some problems would take the age of the universe to solve. A quantum system, by contrast, operates in the quantum realm itself, offering dramatic speedups on a narrow class of problems. But forty years later, the technology is still in what Sorensen calls the “noisy intermediate-scale quantum” (NISQ) era. The “noisy” part is critical: quantum systems are error-prone. You don’t run a quantum algorithm once and get an answer; you run it a thousand times and get a histogram of outputs, hoping the correct answer appears 78 or 80 percent of the time.

What you'll learn
- 1 (00:06) **Episode Introduction & Framing** - Shayle Kann sets up the episode: $12B into quantum startups last year, $50B+ in government commitments, and the big promises (break encryption, design drugs, simulate molecules). The core question: how close are we to the promised land?
- 2 (03:08) **Current State & Brief History of Quantum Computing** - Bob starts with Richard Feynman’s insight: quantum phenomena are intractable for classical computers. Quantum systems are “sandboxes” to simulate the quantum realm.
- 3 (04:54) **Where Are We on the Journey? From Science Experiment to Product** - Bob describes the shift from “when?” (5-6 years ago) to now, where systems can be ordered for delivery.
- 4 (07:05) **Has Quantum Demonstrated a Real Advantage Yet?** - Shayle presses: has anyone solved a real problem faster? Bob explains that benchmark claims are often misleading.
- 5 (10:49) **Why the Gap Between Toy Problems and Real Applications?** - Shayle asks why Plinko-like problems can’t be quickly translated to, say, route optimization. Bob explains the core challenge: algorithm development.
- 6 (14:36) **Is Hardware Good Enough Now? The NISQ Era and Error Correction** - Bob introduces the “Noisy Intermediate-Scale Quantum” (NISQ) era, which is ending. Noise means you run an algorithm 1000 times and get a histogram of results—it’s statistical.
- 7 (18:09) **How to Get to Fault Tolerance: Multiple Levers** - Shayle asks about the ratio of physical to logical qubits. Bob explains progress on all fronts: more reliable hardware, architectural improvements, and better software/algorithms.

Show Notes
Over the course of the past decade, quantum computing (or the concept thereof) has ridden hype cycles, just like AI or the internet writ large.
In the past year, however, as governments across the globe have committed north of $50 billion to the sector, and billions more have poured into quantum startups, the technology is finding itself in the midst of a particularly dramatic hype wave.
Yet even as the money pours in, quantum remains a nascent technology that hasn’t seen any use in the real world. Among other applications, it offers enormous potential to revolutionize material discovery and molecular design, and to turbo charge clean energy tech. But how close we are to actually moving from isolated chips in a lab to bringing these real-world commercial applications to life remains a bit of a mystery.
In this episode, Shayle speaks to Bob Sorensen, chief analyst for quantum computing at Hyperion Research. They dig past the VC hype to map out the current state of quantum hardware, look at the timeline for fault-tolerant computing, and evaluate where the true performance gains lie.
Shayle and Bob discuss:
- Why recent claims of "quantum advantage" are often based on artificial constructs without much real-world relevance
- The difference between physical and logical qubits, and why reducing the "noise" is a defining hurdle for the hardware industry
- How data-driven AI models and science-driven quantum architectures complement each other differently in materials discovery
- Why 85 independent hardware vendors are far too many for the current ecosystem, and how market consolidation might impact investor confidence
