Oskar J. Painter

Oskar J. Painter is the John G. Braun Professor of Applied Physics and Professor of Physics at the California Institute of Technology. He leads the Quantum Photonics Group (QPG), which focuses on quantum photonic devices, superconducting quantum circuits, and precision optomechanical sensors.

• Education: B.S. from University of British Columbia (1994), M.S. (1995), and Ph.D. (2001) from Caltech.

His research spans superconducting metamaterials, hybrid quantum circuits, and optomechanical systems. The QPG explores the integration of microwave-frequency acoustic phonons with superconducting qubits to enable novel quantum transducers and memory elements. They also investigate non-Markovian dissipative environments for quantum state engineering.

The QPG's work includes advancements in cavity QED with atomic-like mirrors, telecom-band quantum optics, and hypersonic crystal electromechanics. Their research aims to realize scalable platforms for quantum information processing and many-body physics simulations using superconducting qubit chains.
