We are looking for a physicist to join our Ion Transport and Waveform Design team. As a simulation physicist, you’ll be part of a cross-functional team whose mission is to lead IonQ on its journey to build the world’s best quantum computers to solve the world’s most complex problems. In this role, you will study the physics of ion transport. You will collaborate with experimental teams to validate simulation results and physics understanding, commercial teams to design transport waveforms used in our quantum computers, and quantum architects to inform the design of next-generation ion traps.

• Develop novel control schemes for fast, robust, and low-excitation ion transport.

• Design and optimize control waveforms to perform operations such as ion loading, transport, qubit routing, and gate operations.

• Simulate the physics of ion chains in the RF Paul traps at the heart of our systems.

• Collaborate with interdisciplinary teams comprising physicists, engineers, and researchers to integrate
