What is quantum computing? List down its characteristics

Answer 1

Quantum computing is a type of computing that uses the principles of quantum mechanics to perform computations. These computers are exponentially faster than classical computers for certain types of problems. The characteristics of quantum computing are:

1. Superposition - A quantum bit or qubit can be in multiple states at the same time.

2. Entanglement - Two qubits can be entangled, meaning that their states are interdependent, even if they are far apart.

3. Quantum Tunneling - Quantum particles can tunnel through potential barriers that would be impenetrable to classical particles.

4. Quantum Decoherence - The state of a quantum bit can be easily disrupted by outside interference.

5. Exponential Speedup - Quantum computers can perform certain types of calculations exponentially faster than classical computers.

6. Probabilistic Outputs - The outputs of quantum computers are probabilistic, meaning that they may not always give the exact answer, but they give a probability of the answer.
