❓ Frequently Asked Questions
What is quantum computing and how does it differ from classical computing?
Quantum computing harnesses quantum mechanical phenomena to perform computations fundamentally different from classical computers. Classical computers use bits (0 or 1) while quantum computers use quantum bits (qubits) that can exist in superposition of both 0 and 1 simultaneously. Quantum entanglement allows qubits to be correlated, enabling complex parallel computations. Quantum interference allows constructive and destructive interference of quantum states. Quantum tunneling enables particles to pass through energy barriers. Decoherence represents loss of quantum properties due to environmental interaction. Quantum supremacy demonstrates quantum computers solving problems classical computers cannot efficiently solve. Quantum algorithms like Shor's algorithm factor large numbers exponentially faster than classical algorithms. Grover's algorithm searches unsorted databases quadratically faster than classical search.
