About the job

Requirements
  • Must be currently enrolled in a university, graduate program, or an equivalent academic institution.
  • Have a background in physics, mathematics, computer science, engineering, or a related field.
  • Have a basic understanding of quantum computation and quantum communication.
Responsibilities
  • Develop and implement a high-performance decoding algorithm for quantum error correction and fault-tolerant quantum computation.
  • Survey and develop quantum or classical error-correcting codes.
  • Design architectural frameworks for fault-tolerant quantum computation tailored to physical systems such as cavity quantum electrodynamics and neutral atoms.
  • Explore fundamental properties of quantum error correction and fault-tolerant quantum computation.
  • Research and develop algorithms and protocols that leverage quantum information processing in areas such as quantum algorithms, communication, cryptography, and sensing.
  • Design efficient algorithms or protocols optimized for fault-tolerant quantum computation or error-corrected quantum repeaters, adapted to physical-system constraints.
  • Contribute to developing a simulator library and hardware application programming interface for cavity quantum electrodynamics-based quantum computers and quantum repeaters.
  • Develop or optimize gate operations, entangled-state generation, and other qubit operations in cavity quantum electrodynamics systems.
  • Conduct fundamental research into light-matter interaction and quantum many-body dynamics in cavity quantum electrodynamics systems.
Desired Qualifications
  • Knowledge of quantum error-correcting codes and fault-tolerant quantum computation.
  • Knowledge of theoretical computer science, such as coding theory and cryptography.
  • Research experience in atomic, molecular, and optical physics.
  • Coding experience in Python or Julia.
  • Extensive experience with simulation libraries for quantum systems, such as QuTiP, QuantumOptics.jl, QuLACS, PennyLane, and Stim.

About the company

NanoQT develops quantum hardware that uses nanofiber cavity QED to connect atoms and photons in an all-fiber system. Its fiber-connected Quantum Processing Unit acts as both a quantum processor and a quantum repeater/interconnect, enabling high-fidelity links over existing fiber networks. The device uses neutral atoms as qubits and photons as information carriers to enable distributed quantum computing via a fiber-based atom–photon interface. Its goal is to enable ultra-secure, long-distance quantum communications by tying together quantum processors across global telecom networks.

Simplify's Take

What believers are saying

  • NanoQT closed a $14 million Series A on September 24, 2025.
  • UMD and Maryland support NanoQT's College Park expansion with Global Gateway and MIPS funding.
  • NEDO backs NanoQT's quantum repeater work and NIST network trials through July 2025.

What critics are saying

  • Distributed quantum computing remains unproven; NanoQT must deliver a working demo after 2025.
  • NanoQT depends on government grants, including NEDO's JPY 492 million program through 2025FY.
  • IonQ and other quantum firms in Maryland compete for the same talent, contracts, and pilots.

What makes NanoQT unique

  • NanoQT's nanofiber cavity-QED interconnect targets neutral-atom QPUs over standard fiber links.
  • Mitsubishi Electric launched a joint trial with NanoQT on April 24, 2025.
  • QuEra collaboration lets NanoQT test networking interfaces on an established neutral-atom QPU.
