  • what   is  quantum   computer?
1.A  Quantum  computer  makes  use  of  the  natural  laws  of quantum mechanics to perform a calculation.

2.quantum computer are extremely powerful and capable than classical computer while doing the task.

3.A quantum computer is a device that performs quantum computing.such a computer is different from binary digital electronic computer based on transistor.


  • what  is  Quantum ?
A classical binary bit always is one of two states _0 or 1_ while a quantum bit  exists in both of its possible states at once,a condition known as a superposition.


→ History   of    Quantum  Computer  

Quantum  computer  tends  to  trace  its  roots  back  to  a  1959   speech  by  Richard p. Feynman in  which  he  spoke  about  the   idea  of  exploiting   quantum  affect  to  create   more  powerful.

         Applications:
   
          ➜ Cryptography
              
                  ➜ Artificial intelligence 
                            
                          ➜ Teleportation

                                                    ➜Quantum communication

                                      
                                   







  •  Quantum  Computer  main  features:



1. uses quantum bits.

2. works with  quantum  parallelism.

3. Entanglement.

4.   keeps  coherence.


  • Quantum computer Requirements :

1. well  defined  extendable  array,  that  allows  to  scale  the  system.

2. the  system  must  be   prepare   in  the [0000...]ground   state.

3. a  universal  set  of  quantum  gates.


      Benefits of  quantum  computer :

  • large sets of  data  can  be  evaluated  much  quicker  than   with   conventional   computers  / parallel  computing.

  • operations  are  reversible  as  long  as  the  resulting  state  is  still  intact.




        what  is  the  IBM  quantum  experience?
  • it  is  web  based  Application   to   :
     . A real  quantum  processor   which  is  currently  working  on  the  IBM   quantum  computing  lab.

. A  simulator   that   allows  to  setup  your  own  topology. 

.     How do quantum computer work ?

→ quantum  computer  perform  calculations  based   on  the  probability  of  an  objects  state  before  it  is  measured- instead  of  just  1 s or  0 s  - which  means  they  have  the  potential  to  process  exponentially  more  data  compared  to  classical  computer.

.  Conclusion:
                         . a quantum  computer  outperformed  a  conventional  machine  by  100  million  times .

.  can  quantum  computers  solve  complete  problems  in  polynomial  time ?

How to create jarvis system / own A.I. assistance Have you want computer like Jarvis. So, your computer will respond to your voice by speaking to you like a human being. Here is procedure how to make   AI System your own just by RAW coding and some tools. Step 1: You have to remove all thing (i.e. all the icons and files) from desktop and set the taskbar to auto hide mode. Follow this: on mouse Right click> view> show desktop icon Step 2: Now download rain meter from given link below: http://rainmeter.net/ After installing rain meter you will see some gadgets on the screen. Step 3: You can move these gadgets just by left-clicking and can do some operations just by a right click. Step 4: Now download these 2 themes from given links: 1.IRON man: http://scrollsofaryavart.deviantart.com/art/IronMan-Jarvis-Theme-Version-2-271590499 2.Avengers: http://chinni1991.deviantart.com/art/Elegant-Theme-1-1-387048490 After downloading these themes install the theme

Stack data structure

Stack Data Structure (Introduction and Program) Stack is a linear data structure which follows a particular order in which the operations are performed. The order may be LIFO(Last In First Out) or FILO(First In Last Out). Mainly the following three basic operations are performed in the stack: Push:  Adds an item in the stack. If the stack is full, then it is said to be an Overflow condition. Pop:  Removes an item from the stack. The items are popped in the reversed order in which they are pushed. If the stack is empty, then it is said to be an Underflow condition. Peek or Top:  Returns top element of stack. isEmpty:  Returns true if stack is empty, else false. How to understand a stack practically? There are many real-life examples of a stack. Consider the simple example of plates stacked over one another in a canteen. The plate which is at the top is the first one to be removed, i.e. the plate which has been placed at the bottommost position remains in the st
