Area of Science:

  • Quantum Information Science
  • Photonics
  • Quantum Computing

Background:

  • Single photons possess multiple degrees of freedom (spatial, temporal, polarization) for encoding quantum information.
  • Current single-photon quantum operations are limited to two qubits.
  • Realizing multi-qubit operations is crucial for advancing quantum information processing.

Purpose of the Study:

  • To experimentally demonstrate three-qubit single-photon quantum gates.
  • To develop a robust and versatile platform for implementing controlled unitary operations on single photons.
  • To generate and verify complex three-qubit entangled states.

Main Methods:

  • Exploiting photon polarization as a control qubit.
  • Utilizing the two-dimensional spatial-parity symmetry of the transverse single-photon field.
  • Employing a polarization-sensitive spatial light modulator for deterministic gate implementation.
  • Performing tomographical reconstruction of single-photon density matrices to confirm generated states.

Main Results:

  • Successful experimental demonstration of three-qubit single-photon linear deterministic quantum gates.
  • Generation of maximally entangled three-qubit Greenberger-Horne-Zeilinger (GHZ) and W states.
  • Confirmation of generated states via tomographical reconstruction, validating the gate operations.

Conclusions:

  • The developed quantum gates provide access to a wide range of three-qubit states and operations.
  • This approach offers a robust, non-interferometric platform for few-qubit quantum information processing.
  • The advancement overcomes previous limitations, enabling more complex quantum protocols using single photons.
