Quantum State Engineering of Light with Continuous-wave Optical Parametric Oscillators

15.0K
We describe the reliable generation of non-Gaussian states of traveling optical fields, including single-photon states and coherent state superpositions, using a conditional preparation method operated on the non-classical light emitted by optical parametric oscillators. Type-I and type-II phase-matched oscillators are considered and common procedures, such as the required frequency filtering or the high-efficiency quantum state characterization by homodyning, are...

It is said that the energy of an electron in an atom is quantized; that is, it can be equal only to certain specific values and can jump from one energy level to another but not transition smoothly or stay between these levels.

Interference and Diffraction

51.8K
Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.

Area of Science:

  • Quantum physics
  • Quantum optics
  • Astrophysics

Background:

  • Classical light sources are typically thermal, and their quantum nature is not easily demonstrable.
  • Quantum phenomena like interference and entanglement are usually studied with controlled, localized sources.

Purpose of the Study:

  • To test quantum interference, entanglement, and nonlocality using two dissimilar photon sources.
  • To demonstrate the quantum nature of thermal light from the Sun.
  • To explore quantum optics experiments at astronomical scales.

Main Methods:

  • Utilized photons from the Sun and a semiconductor quantum dot, separated by ~150 million kilometers.
  • Made vastly dissimilar photons indistinguishable in all degrees of freedom.
  • Observed time-resolved two-photon quantum interference and postselected two-photon entanglement.

Main Results:

  • Achieved a raw visibility of 0.796(17) for two-photon quantum interference, exceeding the classical limit.
  • Demonstrated postselected two-photon entanglement with a state fidelity of 0.826(24).
  • Showed a violation of Bell inequality by 2.20(6).

Conclusions:

  • Provided unambiguous evidence for the quantum nature of thermal light.
  • Established entanglement and nonlocality between photons from disparate sources.
  • Opened a new route for quantum optics experiments at astronomical scales.
