Are you looking for an exciting opportunity to join a dynamic and growing team in a fast paced and challenging area? This is a unique opportunity for you to work with Global Technology Applied Research (GTAR) center at JPMorgan Chase. The goal of GTAR is to design and conduct research across multiple frontier technologies, in order to enable novel discoveries and inventions, and to inform and develop next-generation solutions for the firm’s clients and businesses.

As a Vice President quantum computing researcher within The Global Technology Applied Research (GTAR), you will develop, investigate, and optimize (both analytically and numerically) protocols for universal fault-tolerant quantum computation, implement these protocols for experimental validation, and use these protocols to execute quantum algorithms fault-tolerantly on quantum computing hardware.

Job responsibilities

• Lead a research agenda for the advancement and validation of state-of-the-art methods for universal fault-tolerant quantum computation on existing and near-term quantum computing hardware

• Lead the development of circuit gadgets and protocols for universal fault-tolerant quantum computation (FTQC)

• Lead the numerical investigation and optimization of fault-tolerant gadgets for real-world execution on quantum computing hardware

• Lead the implementation and experimental validation of protocols for universal FTQC on quantum computing hardware

• Document analytical, numerical, and experimental results in scientific papers

• Implement, maintain, and manage a codebase that colleagues without expertise in quantum error correction (QEC) or fault-tolerance can use to run quantum algorithms fault-tolerantly on quantum computing hardware

Required qualifications, capabilities, and skills

• Ph.D. degree in computer science, physics, math, engineering, or related fields, or equivalent experience, plus at least 2 years of relevant experience (industry or postdoc)

• Fluency with the basics of qubit-based stabilizer QEC: stabilizer and subsystem codes; CSS codes; parity check matrices; logical and gauge operators; thresholds and pseudo-thresholds; Clifford and non-Clifford gates; Shor, Steane, and Knill QEC; code distance and effective (circuit) distance
