Beyond Binary
Classical computers think in 0s and 1s. Quantum computers think in probabilities.
The Qubit
A qubit can exist in a state of superposition, being both 0 and 1 simultaneously until observed.
pythonfrom qiskit import QuantumCircuit # Create a Quantum Circuit acting on a quantum register of three qubits circ = QuantumCircuit(3) # Add a H gate on qubit 0, putting this qubit in superposition. circ.h(0) # Add a CX (CNOT) gate on control qubit 0 and target qubit 1 circ.cx(0, 1) # Add a CX (CNOT) gate on control qubit 0 and target qubit 2 circ.cx(0, 2)
Why it Matters
Shor's algorithm can theoretically break RSA encryption. This means our current security infrastructure has an expiration date.
Quantum Chip
We must adapt now. Post-quantum cryptography is not optional; it is survival.
