Job description

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 withGlobal Technology Applied Research(GTAR) center at JPMorganChase. 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 Senior Associate 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

• Develop circuit gadgets and protocols for universal fault-tolerant quantum computation (FTQC)
• Numerically investigate and optimize fault-tolerant gadgets for real-world execution on quantum computing hardware
• Implement and experimentally validate 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
• Competency in 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
• Experience with analytical and numerical circuit-level investigation of QEC and FTQC: constructing circuits for QEC cycles, state preparation, and logical operations; specifying noise models; building detector error models; running numerical simulations; decoding; computing logical error rates
• Experience building quantum circuits in a major software framework such as Cirq, Qiskit, or Pytket
• Fluency in at least one of: Python, Julia, C++, Rust
• Strong oral and written communication skills, strong scientific publication record

Preferred qualifications, capabilities, and skills

• Experience developing a successful research program focused on the development of protocols for universal FTQC
• Experience designing fault-tolerant gadgets for state preparation and logical gates
• Understanding of magic-state distillation and cultivation protocols
• Understanding of generalized code surgery, code adapters and extractors
• Understanding of concatenated code constructions and code families
• Understanding of dynamical codes
• Understanding of ZX calculus and fault-tolerant rewrites and experience with circuit-level quantum compilation
