As Lead Quantum Engineer Readout you will lead initiatives to optimize superconducting qubit readout and reset on our quantum processors and faulttolerant prototypes. Working alongside theorists as well as the hardware and device design teams you will develop and execute on wideranging experimental programs to empirically characterize and improve measurement protocols signal chains amplifiers and device designs. Using the resulting empirical and theoretical models you will develop fast highfidelity readout and reset in our most advanced quantum computers.
Key Responsibilities
Lead Rigettis experimental programs to characterize and improve the full readout stack
Develop models for readout performance (both inside and outside of the rotating wave approximation) and use them to design readout circuits capable of fast highfidelity operation
Identify novel measurement techniques and pulse optimizations to better characterize and improve readout performance and implement these in Rigettis Pythonbased calibration and characterization software
Corroborate experimental results with detailed theory and simulation
Work with the hardware and device design teams to design shortloops and testchips intended to isolate relevant aspects of the full readout stack and accelerate R&D
Develop fast qubit reset protocols to accelerate circuit and enable errorcorrecting codes
Optimize Rigettis readout for quantum error correction including high fidelity rapid midcircuit measurement and ancilla readout
Collaborate with diverse teams of engineers and scientists in device theory algorithms software control hardware chip design and gate operation
Required Qualifications
