What We Build

Efficient quantum infrastructure for when every photon counts

Photon Queue develops quantum memories that are useful today, not ten years from now. Our devices store, synchronize, and release photons with the fidelity and efficiency that utility-scale quantum systems demand — in a compact, room-temperature package that’s ready to integrate.

Why Choose Photon Queue

  • High Efficiency.

    High Efficiency.

    Our optical delay line memories are designed to store and release photons with high efficiency, helping quantum systems preserve valuable photonic states.
  • Broad wavelength compatibility.

    Broad wavelength compatibility.

    Photon Queue memories offer ultra-broad bandwidth at virtually any operating wavelength.
  • High fidelity.

    High fidelity.

    Our linear-optics approach ensures quantum information is preserved across multiple qubit encoding.

What We Enable

Photon storage for quantum systems

Quantum systems must be connected to scale, and our technology enables that connection.

  • 01

    Configurable multiplexing

    Store and release photons on demand — synchronizing asynchronous sources into a unified, coherent output.
  • 02

    Photon buffering

    Fixed-delay reflection cells that keep photons alive while the rest of your system catches up.
  • 03

    Qubit conversion

    Bridge polarization and time-bin encodings — converting between qubit encodings without sacrificing fidelity.

DESIGN YOUR MEMORY

System Specifications

For general planning purposes. Test different loop durations for your application and see how that effects efficiency.

Control Panel

Min Duration: 10 ns
Max Duration: 10000 ns
For 1 – 2 loop systems, set unused loop durations to 0
For 2 – 3 loop systems, loop durations should be integer multiples of the shortest loop
