Detailed explanation-1: -Quantum computers excel at complex problem solving. The unique properties of qubits let them solve certain classes of problems faster and more efficiently than traditional computers. Quantum technology is advantageous for materials science, pharmaceutical research, subatomic physics, and logistics.
Detailed explanation-2: -Researchers typically estimate that it will be many years until quantum computers can crack cryptographic keys-the strings of characters used in an encryption algorithm to protect data-faster than ordinary computers.
Detailed explanation-3: -The main advantage of quantum computing is the ability to work with data in different dimensions at once. This feature allows quantum computers to perform many calculations simultaneously and increase their processing power exponentially, solving complex problems that are impossible on classical computers.
Detailed explanation-4: -Strong encryption begins with a source of genuine randomness (entropy); numbers used to seed keys must not be vulnerable to prediction or bias. In the quantum era, randomness will become even more crucial because quantum computers will be able to ascertain patterns much quicker than classical computers.
