As a Senior Quantum Engineer, Readout, you will optimise superconducting qubit readout and reset on Rigetti's quantum processors and fault-tolerant prototypes. You will lead a range of experimental efforts to characterise 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 fulfil its ambitious roadmap toward fault tolerance. Key responsibilities include leading superconducting qubit measurements to characterise dispersive readout of quantum circuits, developing novel measurement techniques and pulse optimisations for readout speed or fidelity, and collaborating with theory and simulation teams to build or validate models that describe readout performance. You will also specify improvements to the quantum chip layout, signal lines, and electronics, work with the hardware and device design teams to build them, and develop protocols to accelerate circuit execution and enable error-correcting codes, including reset, mid-circuit measurement, and ancilla readout. A Ph.D. in Physics, Applied Physics, Electrical Engineering or a related field, plus 2+ years of industry and/or postdoctoral experience, is required. Deep expertise in circuit quantum electrodynamics and dispersive readout in particular is essential, as is demonstrated ability to perform measurements on quantum systems and explain the results through theory and/or simulation. Experience with software development in an industry setting, in languages such as Python, C, C++, Rust, etc., is also necessary, as is experience with low-level pulse optimisation of quantum gates or readout. Ability to excel in a collaborative environment and excellent communication skills are also required.
