Description

The Leidos Quantum Incubator has an opening for a Quantum Networking Theorist with a background in quantum information science. This is an exciting opportunity to use your experience to help grow the Leidos quantum technologies portfolio of contract and internal R&D projects, benchmarking, and operational prototypes.  In this position, the Quantum Networking Theorist will participate in the full life cycle of research & development of optical systems for the study of quantum-enabled remote sensing and communications. Ideal candidates should be interested in a career devoted to applied research and development with strong mathematical and software skills and should be interested in maturing technologies from concept to prototype.

Primary Responsibilities

• Design, simulate, and analyze cutting edge devices in quantum communication, sensing, and precision positioning, navigation, and timing

• Develop new concepts for quantum communication and distributed quantum device protocols

• Design software to create high-fidelity simulation of quantum communications, photonics, or sensing experiments.

• Collaborate with other team members, engineers, and scientists across the company and different fields to leverage quantum technologies to achieve mission goals

Multiple openings at various levels. The various position’s minimum education and experience requirements are as follows:

• T3: Bachelor’s degree in physics, engineering, or related fields and 4+ years of prior relevant experience. Additional years of experience may be considered in lieu of degree requirements.

• T4: Bachelor’s degree in physics, engineering, or related fields and 8+ years of prior relevant experience. Additional years of experience may be considered in lieu of degree requirements.

Basic Qualifications:

• Research experience in one or more of the following areas: CV and DV quantum optics, quantum entanglement structure theory, quantum communications protocols, quantum information science, quantum error correction, and entangled quantum sensing

• Familiarity with quantum information software tools such as Qiskit, Pennylane, SeQUeNCE, QuTIP, etc.

• Experience developing innovative solutions based upon the application of relevant research results from a wide variety of sources
