Entanglement is one of the strangest phenomena predicted by quantum
mechanics, the theory that underlies most of modern physics. It says
that two particles can be so inextricably connected that the state of
one particle can instantly influence the state of the other, no
matter how far apart they are.
Just one century ago, entanglement was at the center of intense
theoretical debate, leaving scientists like Albert Einstein baffled.
Today, however, entanglement is accepted as a fact of nature and is
actively being explored as a resource for future technologies
including quantum computers, quantum communication networks, and
high-precision quantum sensors.
Entanglement is also one of nature's most elusive phenomena.
Producing entanglement between particles requires that they start out
in a highly ordered state, which is disfavored by thermodynamics, the
process that governs the interactions between heat and other forms of
energy. This poses a particularly formidable challenge when trying to
realize entanglement at the macroscopic scale, among huge numbers of
particles.

Quantum entanglement is a myth. Even the most sophisticated
so called experimental proofs of the mystical powers of QT are
essentially hoaxes. And can be explained classically.

Quantum entanglement is a physical phenomenon that occurs when pairs
or groups of particles are generated or interact in ways such that
the quantum state of each particle cannot be described
independently—instead, a quantum state may be given for the system as
a whole.
Measurements of physical properties such as position, momentum, spin,
polarization, etc. performed on entangled particles are found to be
appropriately correlated. For example, if a pair of particles is
generated in such a way that their total spin is known to be zero,
and one particle is found to have clockwise spin on a certain axis,
then the spin of the other particle, measured on the same axis, will
be found to be counterclockwise; because of the nature of quantum
measurement. However, this behavior gives rise to paradoxical
effects: any measurement of a property of a particle can be seen as
acting on that particle (e.g. by collapsing a number of superposed
states); and in the case of entangled particles, such action must be
on the entangled system as a whole. It thus appears that one particle
of an entangled pair "knows" what measurement has been performed on
the other, and with what outcome, even though there is no known means
for such information to be communicated between the particles, which
at the time of measurement may be separated by arbitrarily large
distances.
Such phenomena were the subject of a 1935 paper by Albert Einstein,
Boris Podolsky, and Nathan Rosen,[1] and several papers by Erwin
Schrödinger shortly thereafter,[2][3] describing what came to be
known as the EPR paradox. Einstein and others considered such
behavior to be impossible, as it violated the local realist view of
causality (Einstein referring to it as "spooky action at a
distance")[4] and argued that the accepted formulation of quantum
mechanics must therefore be incomplete. Later, however, the
counterintuitive predictions of quantum mechanics were verified
experimentally.[5] Experiments have been performed involving
measuring the polarization or spin of entangled particles in
different directions, which — by producing violations of Bell's
inequality — demonstrate statistically that the local realist view
cannot be correct. This has been shown to occur even when the
measurements are performed more quickly than light could travel
between the sites of measurement: there is no lightspeed or slower
influence that can pass between the entangled particles.[6] Recent
experiments have measured entangled particles within less than one
one-hundredth of a percent of the travel time of light between
them.[7] According to the formalism of quantum theory, the effect of
measurement happens instantly.[8][9] It is not possible, however, to
use this effect to transmit classical information at
faster-than-light speeds[10] (see Faster-than-light → Quantum
mechanics).
Quantum entanglement is an area of extremely active research by the
physics community, and its effects have been demonstrated
experimentally with photons,[11][12][13][14] electrons, molecules the
size of buckyballs,[15][16] and even small diamonds.[17][18] [19][20]
Research is also focused on the utilization of entanglement effects
in communication and computation.
