Houck shares insights from his leadership roles at both Princeton and the Center for Co-Design of Quantum Advantage (C2QA), focusing on how interdisciplinary efforts are pushing the boundaries of coherence times, materials science, and scalable quantum architectures. The conversation covers the importance of co-design across the quantum stack, the challenges and surprises in improving qubit performance, and the vision for the next era of quantum research.KEY TOPICS DISCUSSEDMission of C2QA:The central goal is to build the components necessary to move beyond the NISQ (Noisy Intermediate-Scale Quantum) era into fault-tolerant quantum computing. This requires integrating expertise in materials, devices, software, error correction, and architecture to ensure compatibility and progress at every level.Materials Breakthroughs:Houck discusses the surprising impact of using tantalum in superconducting qubits, which has significantly reduced surface losses compared to other metals. He explains the ongoing quest to identify and mitigate sources of decoherence, such as two-level systems (TLSs) and interface defects.Co-Design Philosophy:The episode delves into two types of co-design:Vertical co-design: Aligning advances in materials, devices, error correction, and architecture to optimize the full quantum computing stack.Cross-platform co-design: Bridging ideas and techniques across different qubit modalities and even across disciplines, such as applying methods from quantum sensing to quantum computing.Error Correction Innovations:Houck highlights breakthroughs like using GKP states for error correction, which have achieved performance beyond the break-even point, thanks to improvements in materials and device design.Bosonic Modes and Custom Architectures:The conversation touches on leveraging native bosonic modes in...","thumbnail_url":"https://img.transistorcdn.com/0bJ0_ffy0r0O2l32QT5Tn9-3l9jtqpUcMVwNZnZXwRM/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS8yZmZl/YmRlZTAxNDY3MWJk/NmI2MGVkMGMxYmFh/MTM2Mi5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
