de Broglie wavelength

De Broglie wavelength

The wavelength γ = h/p associated with a beam of particles (or with a single particle) of momentum p; h = 6.626 × 1034 joule-second is Planck's constant. The same formula gives the momentum of an individual photon associated with a light wave of wavelength γ. This formula, along with the profound proposition that all matter has wavelike properties, was first put forth by Louis de Broglie in 1924, and is fundamental to the modern theory of matter and its interaction with electromagnetic radiation.

Although a reduced de Broglie wavelength (60) has been reported for three, (61) four, (62),(63) and even six (64) photons, the SQL has only been beaten with two photons.
We also demonstrated that measurement of a reduced de Broglie wavelength does not mean beating the SQL, via another experiment, which shows high-visibility multi-photon fringes, but cannot beat the SQL.
Furthermore, since the electron possesses a de Broglie radius (with a corresponding de Broglie wavelength 2nrd), it exhibits a wave-like nature throughout the trajectory.
