As Senior Quantum Engineer, Readout, you will optimize superconducting qubit readout and reset on Rigetti’s quantum processors and fault-tolerant prototypes. You will lead a range of experimental efforts to characterize and improve measurement protocols, signal chains, amplifiers, and device layouts. In collaboration with an interdisciplinary group of engineers in theory, hardware, and chip design, you will advance the speed and fidelity of readout and reset in Rigetti Computing’s quantum computing systems to fulfill its ambitious roadmap toward fault tolerance.
Key Responsibilities
Lead superconducting qubit measurements to characterize dispersive readout of our quantum circuitsDevelop novel measurement techniques and pulse optimizations for readout speed or fidelity, and implement them in Rigetti’s Python-based calibration and characterization softwareCollaborate with theory and simulation teams to build or validate models that describe readout performanceSpecify improvements to the quantum chip layout, signal lines, and electronics, work with the hardware and device design teams to build themDevelop protocols to accelerate circuit execution and enable error-correcting codes, including reset, mid-circuit measurement, and ancilla readout
Required Qualifications
