FAQs
What is quantum entanglement, and why is it important?
Quantum entanglement is a phenomenon where two or more particles become connected in such a way that the state of one particle instantly affects the state of the others, regardless of the distance between them. It’s important because it forms the basis for secure quantum communication.
Can any problem be solved by quantum computers more quickly than by traditional ones?
No, quantum computers are not universally faster than classical computers. They excel in specific areas, such as optimization and simulating quantum systems, but for many everyday tasks, classical computers remain efficient.
How can I get started with quantum computing?
If you’re interested in quantum computing, you can begin by studying quantum mechanics, programming languages like Qiskit or Cirq, and exploring online resources and courses offered by institutions and organizations.
What are the limitations of quantum computing?
Quantum computers are still in their developmental stage and face challenges such as qubit stability, error correction, and scaling. They are not yet ready to replace classical computers for all tasks.
