1. 
   1. What is Quantum Computing?
   • Quantum computing harnesses the principles of quantum mechanics to perform computations that classical computers struggle with.
   • Unlike classical bits, which can be either 0 or 1, quantum bits (qubits) can exist in a superposition of both states simultaneously.
   • Quantum computers leverage phenomena like quantum entanglement and quantum superposition to manipulate qubits and solve complex problems.

2. How Does It Work?

   • Quantum algorithms are designed to efficiently perform calculations on quantum computers.
   • However, building and maintaining high-quality qubits is challenging due to quantum decoherence caused by interactions with the environment.
   • Quantum computers are inherently nondeterministic, providing probabilistic results upon measurement.
   • Quantum advantage lies in time complexity, allowing exponential speedup for specific tasks compared to classical computers.

3. Applications and Challenges:

   • Quantum computers could revolutionize fields like cryptography, drug discovery, and optimization.
   • Challenges include noise, error accumulation, and scalability.
   • While quantum speedup is not universal, it holds promise for certain tasks.
