Quantum Concepts - 5/5: Decoherence Quantum states are fragile — and decoherence is the reason. A qubit isn’t “broken”… it’s leaking information to its environment (heat, noise, tiny interactions). That leak scrambles the phase, so superposition entanglement fade. That’s why quantum computing is a race against time: do the calculation before the qubit starts acting like a normal bit #QuantumComputing #QuantumPhysics #Qubits #Decoherence #Superposition
