There’s something quietly radical about using the ordinary to unlock the extraordinary. In a modest lab tucked inside the UK’s tech scene, Quantum Motion has done just that: built a quantum computer using standard CMOS technology. Yes, that CMOS—the same unassuming architecture running inside your phone, your laptop, even the servers quietly humming along behind every online search. It’s the infrastructure of modern life, rarely noticed, always working.
And that’s what makes this so interesting. Because instead of chasing the exotic, Quantum Motion has chosen to build quantum hardware using tools we already know. It’s not flashy. But it’s deeply strategic. CMOS—complementary metal–oxide–semiconductor—has been the foundation of electronics for decades. We’ve already built a global ecosystem around it. So if quantum processors can be made using the same basic process, we’re not just inching closer to practicality. We’re stepping into it with both feet.
This shift isn’t just technical. It’s tactical. Think of the advantage: no need to reinvent fabrication plants, no need to create entirely new supply chains or retrain a workforce from scratch. The infrastructure already exists. Billions of transistors are produced each year with astonishing precision. Quantum Motion isn’t betting on novelty. They’re betting on compatibility, on scaling what we already understand.
What lies at the core of this new apparatus? Spin qubits. Tiny packets of quantum information, each encoded in the spin of a single electron, are trapped in silicon. They’re quiet. Compact. They are significantly less demanding than superconducting qubits, which require near-absolute zero temperatures and highly specialized materials. These spin qubits thrive in silicon, which is key. Because to build quantum computers that move beyond the lab, one must consider fault-tolerant, stable machines with millions of qubits. We need a qubit that fits into the systems we already know how to build.
But Quantum Motion didn’t stop with compatibility. They leaned into modularity. Instead of creating a monolithic processor that does everything all at once, they’re designing quantum modules that are smaller, networked components that can be scaled up and connected, much like classical computing has evolved from single-core to multi-core to distributed systems. It’s a more organic way to grow, and it makes development less brittle. You can test, iterate, adjust, and add capacity without tearing everything down.
And yes, we’re still early. These aren’t million-qubit machines yet. We’re talking small, delicate prototypes. However, the significance lies not just in the number of qubits. It’s in the how. Quantum Motion has demonstrated a path that feels… familiar. That’s the real twist. We’re not waiting for some miraculous materials breakthrough or sci-fi cooling chamber. We’re examining silicon using tools we already have. We already possess the necessary knowledge. We have refined these processes over the course of several decades.
This might be one of the most grounded leaps in quantum history. No fireworks, just a quiet alignment of things that work. It’s the kind of shift that doesn’t announce itself with a bang, but one day you look around and realize everything is different. And it happened because someone asked a simple question: what if quantum could be built like everything else?
