Quantum entanglement (1).pptx

Quantum entanglement is a phenomenon where the quantum properties of two or more particles become linked in such a way that measuring one particle instantly affects the other, even if they are separated by a large distance. Einstein referred to this as "spooky action at a distance" as it appears to contradict relativity. When the spin of one entangled particle is measured, the other particle will automatically resolve to the opposite spin instantaneously. This effect seems to allow faster-than-light communication, though the exact mechanism remains unclear. Potential applications include quantum computing and teleportation.

z QUANTUM ENTANGLEMENT
z 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'.
z 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.
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.
z z WHY?
z FIRST INTERPRETATION  The two entangled particles may be linked by some kind of electromagnetic “force/link”.
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.
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.
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.
z APPLICATIONS QUANTUM COMPUTING QUANTUM TELEPORTATION
z 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.
