Colder Than Space: Quantum Hardware and the Race for Logical Qubits

Deep End Era. Engineering with Sankalp · Oct 28, 2026 · 54m

Fictional hardware engineer Wilhelmina Ostrowski gives pharmaceutical chemist Fergus Adeyemi an honest tour of quantum computing. We cover superposition, interference and entanglement, Shor, Grover and quantum simulation (FeMoco), decoherence, the NISQ era and D-Wave, the three-qubit code worked by hand, the threshold theorem and surface code, transmons and Google's Willow below-threshold result, trapped ions and Quantinuum Helios, neutral atoms and the Harvard/QuEra results, photonics, Microsoft's Majorana claims, cat qubits, the engineering inside the fridge, seven questions to ask of any…
