Description

About the NASA Postdoctoral Program

The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.

Description:

Future NASA missions ranging from deep-space navigation to high-precision gravitational wave detection will increasingly rely on quantum-enhanced technologies. However, the current state-of-the-art for generating entangled photons involves bulky, alignment-sensitive bulk-optic assemblies. These systems are ill-suited for the rigorous vibration, thermal cycling, and radiation environments of space flight. To bridge the gap between laboratory-grade quantum optics and flight-ready hardware, there is an urgent need for Photonic Integrated Circuit (PIC) platforms that can generate high-fidelity entanglement on a robust, chip-scale architecture.

• Background and Relevance to NASA

This research directly supports NASA’s mission to develop disruptive technologies for the Integrated Network (IN) and Quantum Sensing initiatives. By shifting entanglement generation to an integrated nonlinear platform, we can achieve unprecedented levels of stability and scalability. This technology is a critical enabler for:

• Space-to-Ground Quantum Networks: Providing the "quantum backbone" for secure data transmission.

• Quantum-Enhanced Sensing: Enabling sub-shot-noise interferometry and high-resolution imaging for Earth science and planetary exploration.

• Fundamental Physics: Facilitating long-baseline Bell tests and relativistic quantum experiments in microgravity environments.

• General Methodology

The postdoctoral researcher will focus on the design, fabrication oversight, and characterization of high-performance integrated quantum sources. The research plan includes:

• Resonant and Non-Resonant Design: Optimizing waveguide geometries and micro-resonator architectures to enhance nonlinear optical conversion efficiency (e.g., via SPDC or SFWM) while maintaining high spectral purity.

• Dispersion Engineering: Tailoring the phase-matching conditions to generate entanglement across various degrees of freedom (polarization, time-energy, or frequency).

• Robustness Characterization: Evaluating the source performance under environmental constraints relevant to NASA, including power-efficiency metrics and thermal stability of the chip-to-fiber interfaces.

• System-Level Validation: Performing quantum state tomography and coincidence measurements to verify entanglement fidelity against mission-specific benchmarks.

• Expected Results and Significance

The primary output of this project will be a high-brightness, chip-scale entangled photon source that demonstrates a significant reduction in Size, Weight, and Power (SWaP) compared to traditional sources. Expected outcomes include:

• Demonstration of high-rate pair generation with fidelities exceeding 90-95% on an integrated footprint.

• Validation of a modular architecture that can be integrated into larger NASA quantum payloads.

• A comprehensive performance map of the PIC source across a range of operational temperatures, ensuring reliability for varied mission profiles.

By miniaturizing these sources, this work paves the way for the deployment of quantum nodes on SmallSats and CubeSats, democratizing access to quantum-enhanced capabilities across NASA’s fleet.
