Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
benefits of quantum computer
A
computers are very fast an powerful, can create and break conventional encryption
B
to provide DC power for internal components of a computer
C
a device that connects to a computer and is used to project the video output from the computer onto a wall or screen
D
connectivity affected by resistance of buildings and interference, limited range, slow
Explanation: 

Detailed explanation-1: -Specifically, a quantum computer could take a publicly available public key and derive the associated private key from it. This means that any data encrypted using that public key could now be decrypted without the consent of the party that sought to protect that data.

Detailed explanation-2: -Quantum computers use quantum bits, or qubits, to measure and extract information. Unlike the bits of classical computers, which can store a 1 or 0, qubits can store multiple values at the same time. This theoretically gives them a huge speed advantage over classical computers and algorithms.
