Amplification at the quantum limit
Development of parametric amplifiers for superconducting qubits at Google Quantum AI to achieve fast single-shot readout.
At Google, the Quantum AI team is building a useful quantum computer using superconducting circuits. Making a quantum computer function well involves fine-tuning different parts, and parametric amplifiers are key components as they allow fast single-shot readout of superconducting qubits. However, optimising their performance is not an easy task. For more on my work with the Quantum AI team, see this Google blog post.
