Quantum’s “impossible problem” is finally shiftingfrom science → engineering.
In Part 2 of myconversation with Yuval Boger (CCO, QuEra)on Beyond the Qubit, we went deep into Error correction, Scaling and the physics that will determine which platforms survive.
Hereare the insights 👇
1. Every qubit technology has a fundamental weakness…until you correct it.
Yuval put itbluntly:
“Qubitsare fragile. Everything in the universe wants to disturb them.”
Cosmic rays,vibrations, electromagnetic noise, even a gate failing 1 in 10,000 times becomes catastrophic when your algorithmrequires millions of operations.
This is why error correction is the real battleground.
Not qubit count.
Not coherence time.
Not marketingslides.
This clicked for me:you don’t win by adding more qubits, you win byadding the right ones.
2. Mobility changes everything about logical qubits.
Most qubit platformsare fixed in place.
Neutral atoms move, and that changes the math.
Yuval gave a visualI can’t unsee:
Two logical qubits,each made of five physical qubits.
Static hardware?
You must connectthem pair by pair, accumulating errorswith every handshake.
Neutral atoms?
➡️ Move the qubits physically
➡️ Apply one pulse of light
➡️ Create all interactionsin parallel
Parallelism → feweroperations
Fewer operations →fewer errors
Fewer errors → farfewer physical qubits needed per logical qubit
Neutral atoms aren’tjust another modality, they’re a differentscaling strategy.
3. The telecom analogy that reframes the entirearchitecture
I comparedsuperconducting qubits to fixed fiber and neutral atoms to wireless networks.
Yuval extended itbeautifully:
If the central nodefails, fixed-line users are stuck.
Wireless? You movethe tower closer and reconnect.
Neutral atomsprovide that same architectural freedom:
4. Neutral-atom scaling isn’t PowerPoint. It’sphysics.
Many companies claimthey’ll scale.
Yuval asked thequestion that matters:
“Areyou relying on miracles, or engineering?”
Neutral atoms scalethrough:
Scale-out acrossmachines? Possible.
But what struck meis that scaling within a single system has aclear physics-based roadmap, unlike many competing architectures.
5. Error correction is no longer theoretical, QuEra isdemonstrating it.
Yuvalwalked through the early steps:
He didn’t revealtheir full roadmap, but the direction is unmistakable.
6. Quantum is becoming practical and customers arevoting with usage, not words.
Yuval shared severalsignals that quantum is crossing from research into industry:
These aren’texperiments, they’re real workloads on real systems.
Talk is cheap; usageis not.
This isn’t hype.
This is earlyindustrialization.
🤔 Which modality do you believe reaches fault-tolerant scale first?
Neutral atoms?Superconducting? Trapped ions? Photonics?
Or somethingcompletely different?
I’d love to hearyour perspective.
