The convergence of quantum information science, cryogenic engineering, and cryogenic electronics is driving a new era in computing. This talk explores the enabling technologies and system-level innovations required for scalable quantum and energy-efficient classical platforms. Utility-scale quantum computers will require millions of qubits, supported by advanced control electronics, high-density interconnects, and cryogenic infrastructure. Cryogenic cooling also offers a path to more efficient classical computing by overcoming thermal limits through custom silicon and superconducting technologies. We will highlight current directions at Emergence Quantum and discuss why cryogenic electronics are foundational to future computing architectures.
