This ppt explains about Quantum entanglement

Quantum entanglement
had riled Einstein who
called it "spooky action at
a distance "as it appears
to contradict the special
theory of relativity .
Later Schrodinger defined
the idea as
'entanglement'.

WHAT IS QUANTUM
ENTANGLEMENT?
 Quantum entanglement is a phenomenon wherein the quantum
properties of two (or more) particles become codependent,
with the properties of one being instantaneously affected by
measurements conducted on the other.

4. z
Example
 A pair of electrons having opposite spins, with the
actual spin of each particle remaining in a state of
quantum uncertainty .On the separation of the
pair of particles, even by a huge distance, and on
measuring one particle’s spin the other particle’s
spin will automatically resolve itself in the other
direction. On the separation of the pair of
particles, even by a huge distance, and on
measuring one particle’s spin the other particle’s
spin will automatically resolve itself in the other
direction. This effect occurs instantaneously,
apparently breaching the velocity of light and the
rules of relativity, a phenomenon that Einstein
referred to as spooky action at a distance.

WHY?

6. z
FIRST INTERPRETATION
 The two entangled particles may be linked by some kind of
electromagnetic “force/link”.

7. z
SECOND INTERPRETATION
 The two entangled particles may theoretically be simultaneously
controlled by a “brain” or “controller”. This “brain/controller” may
theoretically issue a signal to both particles at the same instant
causing them to act as they do at the same instant.

8. z
THIRD INTERPRETATION
 Information from one of the two entangled particles may
theoretically be carried to the other particle by an extremely fast
carrier wave that travels faster than the velocity of light causing
the other particle to act with an opposite spin at practically the
same instant .These particles are known as Tachyons.

9. z
 Quantum entanglement does in fact happen and entangled
particles do appear to “communicate” with each other across
space faster than the velocity of light. Experiments with more
than two entangled particles switching states together across
many tens of kilometers have already been conducted.

QUANTUM COMPUTING
 Calculations currently uses binary operations
 Recent use of particles 'Quantum states', with calculations
performed using principle of superposition .
 Information stored as qubits.
 Calculations based on end product of interference.
 Quantum computers should be more efficient by 2030.
