The de Broglie Wavelength02:32

The de Broglie Wavelength

25.7K
In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Electromagnetic Waves in Matter

2.8K
Electromagnetic waves can travel in the vacuum as well as in matter. For example light, which is an electromagnetic wave, can travel through air, water, or glass.
Consider the electromagnetic wave passing through a dielectric medium. In such a case, Maxwell's equations get modified. In Ampere's law, ε0 , the dielectric permittivity of free space is replaced with ε, the permittivity of dielectric. Also, the vacuum permeability μ0 is replaced by the permeability of the medium,...

Area of Science:

  • Quantum Information Science
  • Solid-State Physics
  • Quantum Optics

Background:

  • Reversible transfer of quantum states between light and matter is crucial for quantum communication.
  • Quantum memories must preserve entanglement during storage for applications like quantum repeaters and networks.
  • Existing quantum memory protocols have limitations in spectral bandwidth.

Purpose of the Study:

  • To demonstrate reversible transfer of photon-photon entanglement into entanglement between a photon and atomic excitation.
  • To develop a broadband quantum memory with enhanced spectral acceptance.
  • To assess the entanglement-preserving capabilities of the developed quantum memory.

Main Methods:

  • Utilized a thulium-doped lithium niobate waveguide.
  • Employed a photon-echo quantum memory protocol.
  • Increased spectral acceptance from 100 MHz to 5 GHz.
  • Assessed entanglement preservation via Bell inequality violations and pre/post-storage entanglement comparison.

Main Results:

  • Achieved reversible transfer of photon-photon entanglement into photon-collective atomic excitation entanglement.
  • Demonstrated a significant increase in spectral acceptance to 5 GHz.
  • Bell inequality violations and entanglement comparison confirmed a near-perfect mapping process, within statistical error.
  • Developed a broadband, integrated quantum memory device.

Conclusions:

  • The developed broadband quantum memory successfully stores and retrieves entanglement with high fidelity.
  • This integrated lithium niobate device simplifies frequency matching for quantum communication interfaces.
  • The advancement brings fully quantum-enabled networks closer to reality.
