Overview
Quantum control electronics is a critical component in the development of quantum computing systems. Qubits, the fundamental building blocks of a quantum processor, require precise electromagnetic pulses in the gigahertz frequency range and latency in nanoseconds for effective control and readout.
Our research addresses three main challenges associated with room temperature electronics used for controlling and measuring superconducting qubits: scalability, direct microwave synthesis, and a unified user interface.
To tackle these challenges, we have developed a scalable indigenous quantum control electronics platform specifically designed for quantum computing systems. This platform ensures that the control and measurement of qubits are both efficient and reliable, paving the way for advancements in quantum computing technology.
Our innovative solutions in quantum control electronics are poised to significantly enhance the performance and scalability of quantum processors, making them more accessible and practical for a wide range of applications.
