Questions & Answers

Q: How are quantum computers different from parallel computers?

Quantum computers are entangled systems with qubits in multiple states, unlike independent processes in parallel computing.

Q: What is the impact of noise on quantum algorithms?

Noise in physical qubits affects quantum states, necessitating high-qubit quality and quantum error correction techniques.

Q: Can quantum computers break internet encryption?

Quantum algorithms like Shor's require millions of qubits for encryption, far exceeding current capabilities, ensuring internet encryption safety.

Q: Is quantum computing's scalability a concern?

Uncertainty exists on achieving functional quantum computers at scale due to noise issues and the need for substantial qubit improvements.

Summary & Key Takeaways

• Quantum computers are not infinitely parallel like standard description implies; qubits in entangled state.

• Difference between theoretical ideal qubits and physical qubits, noise impact, and quantum error correction.

• Internet encryption safety due to current qubit limitations and uncertainty of quantum computing scalability.
