“What does the ultimate computer look like under the laws of physics?”

That’s the question Ish Dhand has been obsessed with for years.It’s also what ledhim from academia, to Xanadu, and now toco-founding QC Design.I’m excited to sharethat Ish is joining me on Beyond the Qubit.What struck me mostin our conversation wasn’t hype or timelines, it was how hard the problem really is.A few takeaways thatstayed with me:• Fault-tolerantquantum computers aren’t blocked by a single breakthrough, but by thousands of interacting design decisions• Error correctionisn’t just a physics problem, it’s an architecture,control, and decoding problem all at once• Many hardwareteams underestimate how early they needto think about fault tolerance• Software canunlock orders-of-magnitude improvements,but only if it’s grounded in realistic noise models and hardware constraintsAt one point, Ishdescribed QC Design as the Cadence / Synopsysof quantum computing.Not building thehardware itself, but helping hardware teams understand what they’re actually building before they build it.What I appreciatedmost was his bias for action:ship early, getfeedback from real hardware teams, iterate fast, even when the problem space ismessy and incomplete.In this episode, wego deep into:• how logical qubitsreally emerge from physical ones• why differentqubit platforms face fundamentally different error profiles• why “software willfix it later” is often the wrong mental model• and what actuallyneeds to go right for fault-tolerant quantum computing to arriveIf you care about how quantum systems are designed,  not just announced,  this is a conversation worth your time.🎙️Beyond the Qubit,  episodewith Ish Dhand🔗 (link)https://youtu.be/GOuYABNmfjM #QuantumComputing#FaultTolerantQuantum #QuantumArchitecture#ErrorCorrection#QuantumSoftware #BeyondTheQubit ⁨@IshDhand⁩ ⁨@QC_Design⁩ 📌 Disclaimer: This post is shared on a personal basis and I do notrepresent any company
