Quantum computing


Quantum computer is a device which uses the quantum phenomenon of superpostion for computation purpose.
      In general computer computation is done on two fundamental aspects true or false(zero and one) in general the glowing bulb represents a true(1) and the other one a false(0)
               
so here the condition may by either true or false oly tow conditions are possible but in case of quantum computer there exist a qbit which can be zero,one or either zero or one at the same time.
which means there a more possible.
If there is a stream of 1's and 0's 101010101110 here each bit can be either zero or one at any instant.
follow the video for further details.. :)
Advantages :
-> more data can be stored
->fast computations
Disadvantages :
->normal programming cannot be applied here
->cant be implemented to all kinds of computing problems
