Questions & Answers

Q: What are the building blocks of a quantum computer?

Quantum computers use quantum bits, or qubits, as their building blocks. Unlike classical bits, qubits can be in multiple states simultaneously, thanks to superposition.

Q: How does entanglement work in quantum computing?

Entanglement is the phenomenon where qubits become part of one large quantum state together. Changing the state of one qubit affects the entire system, regardless of the number of qubits.

Q: Are there any limitations to quantum computers?

Quantum computers face challenges like decoherence and scalability. Decoherence occurs when qubits interact with the environment, causing information loss. Scalability becomes an issue as the number of entangled qubits increases.

Q: What are some potential applications of quantum simulation?

Quantum simulation can be used to improve solar panels, batteries, develop new drugs, chemicals, materials, and study climate change. It allows for faster and more cost-effective testing of different physical parameters.
