Quantum computing is no longer defined solely by qubits — it’s increasingly shaped by how we measure, control, and integrate entire systems. Many of the breakthroughs driving progress today, from high-fidelity readout to real-time feedback, stem from advances in quantum measurement science.

These capabilities are critical to scaling quantum processors and enabling practical error correction.At the same time, innovation is being accelerated by regional ecosystems and national initiatives, where universities, national laboratories, and industry work together to build scalable quantum platforms. California has emerged as a leading hub in this model, anchored by UC Berkeley and Lawrence Berkeley National Laboratory, alongside a rapidly expanding startup landscape.

In this conversation, Prof. Irfan Siddiqi — Professor at UC Berkeley, Faculty Scientist at Berkeley Lab, and Director of the Advanced Quantum Testbed — brings a firsthand perspective from the forefront of the field. A pioneer of quantum measurement science and real-time quantum control, his work bridges foundational physics, system engineering, and large-scale collaboration.
