The Last Stop on the Railroads Series
This is the third (and final) installment of our Railroads of… series.
We covered space. We covered robotics. Today we close the trilogy with the one that may make all of the above run faster, cheaper, and stranger than anything we've yet seen.
Welcome to the railroads of quantum computing.
What Quantum Computing Actually Is
Forget the marketing hype for a second. The thing that makes quantum computing different is one idea: the qubit.
Classical computers think in zeros and ones. Quantum computers add a third state — a qubit — that can be a zero, a one, or both at once.
That "both at once" part isn't a faster computer. It's a fundamentally different way of analyzing a problem.
The maze analogy works best. A classical computer solving a maze walks every path one at a time and tells you which one was right. A quantum computer walks every path simultaneously and tells you the answer instantly.
The implications get vivid quickly. An 8-character password that would take a classical computer "a couple of lifetimes" to crack? A quantum computer can do it in about an hour.
That single fact is why every major government, every major tech company, and every major cybersecurity firm is paying very close attention.
Why This Matters Beyond Cryptography
Cybersecurity is the headline. The bigger story is everywhere else.
- Logistics & supply chain optimization. Every 1% improvement in global supply-chain efficiency is worth billions.
- Pharmaceutical drug discovery. Compressing the timeline from molecule to FDA approval could be worth billions per drug.
- AI acceleration. When quantum and AI eventually merge — and they will — the combined capability is genuinely hard to predict.
- Financial modeling. Risk and portfolio optimization at scales that simply aren't tractable today.
- Materials science & energy. Better batteries, better catalysts, better everything that involves modeling atoms.
This is another trillion-dollar idea hiding in plain sight.
Whether we hit that scale in this decade or the next is the open question.
The Three Pick-and-Shovel Layers
If you've followed the prior two episodes in this series, the structure will feel familiar:
- Cloud platforms — Quantum-as-a-Service. Most enterprises will never own a quantum computer; they'll rent time on one. The cloud providers win that fight.
- Hardware — semiconductors, cryogenics, control systems. Quantum computers run at near-absolute-zero temperatures. Whoever makes the cooling work, makes a lot of money.
- Software & hybrid computing — the layer that translates "I have a problem" into "here's the qubit instruction set that solves it." A real frontier — and a real opportunity.
The Pure-Play Quantum Names
Here are the names actually trying to build the machines themselves. These are highly speculative, not yet profitable, and have moved in both directions violently. None of these are recommendations.
- Rigetti Computing (RGTI) — superconducting qubits, vertically integrated. Stock has moved in a range of roughly +500% to +5,700% over the trailing window. High capital intensity — the business burns money to make money.
- IonQ (IONQ) — trapped-ion quantum, the high-accuracy approach. ~$130M in 2025 revenue, still losing money. Partnered with AWS. Trailing returns roughly +250% to +700%.
- D-Wave Quantum (QBTS) — more commercial use cases today than peers, less flexible technically. Trailing returns roughly +200% to +1,000%.
- Quantum Computing Inc. (QUBT) — photonics and quantum-inspired systems. Trailing returns around +1,000%.
When you see numbers like that, slow down. By the time the average retail investor reads about these stocks, sophisticated investors have already been in for a year. The hottest news is often the worst entry point.
The Big-Tech Quantum Plays
If you want exposure to quantum and a profitable, well-capitalized business behind it, this is the more reasonable lane:
- IBM — arguably the leader in enterprise quantum cloud work, running a serious superconducting quantum program.
- Alphabet / Google (GOOGL) — nearly bottomless R&D budget, and crucially, ownership of the training data. Good data is the limiting reagent here.
- Microsoft (MSFT) — the Azure Quantum platform, betting across multiple qubit architectures. If quantum hits Excel and Office at scale, this becomes enormous.
- Amazon (AMZN) — AWS Braket as a quantum cloud, plus their growing chip-manufacturing footprint.
The simplest read: the pure-play names give you the upside and the heart attack. The big-tech names give you exposure with a balance sheet behind it.
The Honest Problems
Every honest investment story has its hole in the floor. Quantum's are real.
- Energy. Cooling a quantum computer is an "outer-space-temperatures" problem. Combine that with the AI energy curve and the grid has a serious math problem.
- Profitability is years away. The pure-play companies are pouring every dollar back into R&D, not into the shareholder.
- Multiples are stretched. Even the better names trade at 30x earnings or far worse. You're paying for a story, not a result.
- Acquisition risk runs both ways. One pure-play company could be acquired by Google at 10x its share price. Another could quietly cease to exist. The same investor probability tree.
- Timeline. The honest analyst consensus is that mainstream quantum impact arrives in the mid-2030s, not next quarter. A decade is a long horizon for a speculative position.
How to Get Exposure Without Betting the Farm
Two approaches we'd suggest considering, in order of seriousness:
1. The barbell approach. Keep the core of your portfolio in stable, profitable, dividend-paying businesses. Allocate a small, contained percentage to speculative names like the pure-play quantum stocks. If they go to zero, you survive. If one becomes the IBM of 2040, you participated.
2. The ETF route. A few baskets worth knowing:
- QTUM — Defiance Quantum ETF. The closest thing to a pure-play quantum basket, though it also includes AI and semiconductor names.
- ARKQ — ARK Autonomous Tech & Robotics. Has quantum exposure folded into its broader tech-disruption mandate.
- BOTZ — Global X Robotics & AI. Crosses over into quantum via several of its holdings.
- ROBO — ROBO Global Robotics & Automation. Industrial-leaning, but also captures quantum-adjacent names.
None of these are recommendations — they're tools to research.
The Big Picture: Why the Railroads Series Mattered
Step back. Look at all three:
- Space gets the satellites and the imagery and the trillion-dollar SpaceX IPO.
- Robotics gives us the labor and the reshored factories.
- Quantum gives all of it a brain that thinks differently.
These three industries don't live in separate boxes. They intersect.
The robot lifted to orbit on a reusable rocket, running quantum-trained logistics from a cloud platform — that isn't science fiction anymore. It's a 10-year roadmap. Quantum computing might be the pick-and-shovel that ultimately makes the other two railroads run.
Quantum is real. It's just very early.
Think back to 2010, when AI was an academic curiosity. Today it's reshaping every industry on the planet. Quantum sits where AI sat 15 years ago.
Be informed. Be intentional. Be a good steward of what you have been entrusted with.

Frequently Asked Question
What is a qubit, and why does it make quantum computing different?
A qubit (quantum bit) is the fundamental unit of quantum computing. Unlike a classical bit, which is either 0 or 1, a qubit can be 0, 1, or both at once — a property called superposition. This lets a quantum computer explore many possible solutions to a problem simultaneously rather than one at a time. That's why quantum computers can theoretically solve certain problems — like cracking encryption, optimizing logistics, or modeling complex molecules — orders of magnitude faster than classical computers, even though they aren't simply "faster computers" in the traditional sense.
