Technical Tools

cpppythonrust

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.

Lead superconducting qubit measurements to characterize dispersive readout of our quantum circuits

Develop novel measurement techniques and pulse optimizations for readout speed or fidelity, and implement them in Rigetti’s Python-based calibration and characterization software

Collaborate with theory and simulation teams to build or validate models that describe readout performance

Specify improvements to the quantum chip layout, signal lines, and electronics, work with the hardware and device design teams to build them

Develop protocols to accelerate circuit execution and enable error-correcting codes, including reset, mid-circuit measurement, and ancilla readout

Ph.D. in Physics, Applied Physics, Electrical Engineering or a related field, plus 2+ years of industry and/or postdoctoral experience

Deep expertise in circuit quantum electrodynamics and dispersive readout in particular

Demonstrated ability to perform measurements on quantum systems and explain the results through theory and/or simulation

Exposure to superconducting qubits, either in academic or industrial settings

Experience with software development in an industry setting, in languages such as Python, C, C++, Rust, etc.

Experience with low-level pulse optimization of quantum gates or readout

Ability to excel in a collaborative environment

Excellent communication skills
