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 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

Required Qualifications

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

As engineering leaders, we value diversity and are committed to building a culture of inclusion to attract and engage innovative thinkers. Our technology, meant to serve all of humanity, cannot succeed if those who built it do not mirror the diversity of the communities we serve. Applications from women, minorities, and other under-represented groups are encouraged.
