Quantum Computing: When Bits Become Qubits
How quantum mechanics will reshape computation within this decade
Classical computers use bits. Quantum computers use qubits that can be 0, 1, or both simultaneously — and this changes everything.
Start here: make a prediction before reading
Quantum computing exploits quantum mechanical phenomena — superposition, entanglement, and interference — to process information in ways classical computers cannot. Where a classical bit is always exactly 0 or 1, a qubit exists in superposition: a combination of both states until measured.
