  • Quantum Information Science
  • Integrated Photonics
  • Quantum Optics

Background:

  • Integrated quantum optical circuits are crucial for single-photon quantum information processing.
  • Essential components like sources, gates, and detectors are available.
  • A critical missing component for on-chip synchronization is a single-photon buffer.

Purpose of the Study:

  • To develop and demonstrate an on-chip single-photon buffer.
  • To facilitate circuit synchronization in photonic quantum information processing.
  • To maintain the non-classical properties and entanglement of single photons.

Main Methods:

  • Utilized a coupled resonator optical waveguide (CROW) structure.
  • The CROW comprised 400 high-Q photonic crystal line-defect nanocavities.
  • Tested buffering of pulsed single photons and time-bin entangled states.

Main Results:

  • Successfully buffered a pulsed single photon for 150 ps with 50-ps tunability.
  • Demonstrated preservation of non-classical photon properties.
  • Showcased entanglement preservation by storing and retrieving one photon from an entangled pair.

Conclusions:

  • The developed CROW serves as an effective on-chip single-photon buffer.
  • This buffer successfully maintains quantum properties and entanglement.
  • Represents a significant advancement towards all-optical integrated quantum information processors.
