The Quantum Control Stack with Niels Bultink

Every quantum computer — superconducting, spin, trapped ion, or neutral atom — depends on a layer most people never see: the precisely timed electronics that play qubits like a microwave-frequency piano and read the answers back. Niels Bultink, co-founder and CEO of Qblox, joins Sebastian to explain why the quantum control stack has become a strategic bottleneck for scaling quantum hardware, and how a Delft spinout is building the picks-and-shovels of fault-tolerant quantum computing while expanding into the U.S. through a Boston headquarters, U.S. manufacturing in Massachusetts, and a partnership with Fermilab on the open-source QICK platform.
