** Bernstein Vazirani Method;

There is a secret number in a box. It is contain with 6 Bits (Zeros & ones)

A classical computer can accomplish this task in 6 tries.

A quantum computer using the (Bernstien Vazirani Method), can do the same task in 1 shot.

Using Secret Number: 101001


Classical Computer Algorithm to Determine What Is In The Box;

Code in Box;
+------------+
| 1 0 1 0 0 1|
+------------+

Classical Computer ~ AND STATEMENTS; (X = No Match | M = Match)

+------------+
| 0 0 0 0 0 1|
+------------+
            M
+------------+
| 0 0 0 0 1 0|
+------------+

Classical Computer Finally Matches Code In Box!

A quantum computer can achieve same goal in 1 try!

This is shown by simulating all possible options at the same time
