- 13. Superposition gives quantum computers superior computing power Superposition Superposition is condition in which a quantum system can exist in multiple states because a qubit is a quantum mechanical system, it can exist in the “0” state, the “1” state, or any state that is a linear combination of 0 and 1. |ψ⟩ = α|0⟩ + β|1⟩
- 14. Entanglement When two qubits are entangled there exists a special connection between them. The entanglement will become clear from the results of measurements. The outcome of the measurements on the individual qubits could be 0 or 1.

- 17. THE PROBLEM the Secret (Number) The Bernstein-Vazirani Algorithm specializes in finding a secret number. (In our case, the number is going to be some bitstring) So say we put a secret number in a box, say it’s 1001 (the number 9 in binary) THE CLASSICAL APPROACH the first guess is always going to be leading zeros, followed by a 1 ' 0001' . Now the algorithm use and AND comparison to see if there’s a 1 in the same spot. We can see that they both have a 1 as the last bit, so this means that the algorithm has found a 1 in that place. (Since AND(1,1) = 1) This series of guesses is repeated for every bit in the secret bitsring. So our next guesses is 0010, then 0100, and so forth. Our algorithm just keeps performing these AND operations to see if there is a 1 in that place.
- 18. we will generate an Oracle(Uf) for function f(x) where f(x) = x ·a, where x shall be the input bits and a shall be the secret string. After applying Oracle the result shall be |a⟩. Let us consider a = 1001, which is a 9 bit string. The expected output for Bernstein-Vazirani problem shall be |1001⟩ The B̶e̶t̶t̶e̶r̶ Quantum Approach
