Abstract
Quantum entanglement is the quintessential characteristic of quantum mechanics and
the basis for quantum information processing. When one of two maximally entangled
particles is measured, without measurement the state of another one is determined
simultaneously no matter how far the two particles is from each other. How can these
phenomena take place since no object can move faster than light speed in a vacuum?
The key problem is due to the ignorance of the interaction between a particle and
a quantum vacuum. Just like the case where a gun suffers recoil from its firing of
a bullet, when a particle is created from the quantum vacuum, the vacuum will be somewhat
"broken" correspondingly, which can be described by a shadow state in the vacuum.
Through their shadows in the vacuum two quantum entangled particles can have a distance-independent
instantaneous interaction with each other. Quantum teleportation, quantum swap, and
wave function collapse are explained in a similar way. Quantum object can be interpreted
as a composite made up of a particle and the shadowed quantum vacuum which is responsible
for the wave characteristic of the particle wave duality. The quantum vacuum is not
only the origin of all possible kinds of particles, but also the origin and the core
of Eastern mystics.
