Eric Kievit, chief executive of Qblox, talks in this video filmed at the 2023 March Meeting of the American Physical Society in Las Vegas about the firm’s approach to quantum technology . This rapidly growing Dutch company specializes in building quantum-computer control stacks.

Bilal Kalyoncu, lead application scientist, explains how the Qblox control stacks support a range of qubit platforms including superconducting qubits, spin qubits and NV centres. He outlines the new Fast Scalable Feedback system, which is built on top of architecture consisting of 120 cores in a single device, all working together. This cluster mainframe is able to distribute measurement outcomes with auto-connectivity, so that up to 80 output channels are linked to up to 40 input channels for feedback operations. This scalable approach brings feedback applications to a level where many qubit quantum error corrections algorithms are possible.

Kalyoncu goes on to explain that Qblox has an open architecture approach and, as part of the Quantum Internet Alliance, collaborates and innovates with other organizations across Europe to accelerate the path to a quantum internet.
