Quantum Computing: Understanding Its Potential Business Applications

Quantum computing represents a paradigm shift in computational power. While still emerging, it promises to solve problems that are impossible for classical computers.

Classical vs Quantum

Classical computers use bits (0 or 1). Quantum computers use qubits that can exist in superposition — being 0, 1, or both simultaneously. This enables exponentially more possibilities.

Quantum Programming: Qiskit Example

# Python — Create a quantum circuit with Qiskit
from qiskit import QuantumCircuit, transpile
from qiskit_aer import AerSimulator

# Create a 2-qubit circuit
qc = QuantumCircuit(2, 2)

# Put qubit 0 in superposition
qc.h(0)

# Entangle qubits 0 and 1 (CNOT gate)
qc.cx(0, 1)

# Measure both qubits
qc.measure([0, 1], [0, 1])

# Simulate
simulator = AerSimulator()
compiled = transpile(qc, simulator)
result = simulator.run(compiled, shots=1000).result()
counts = result.get_counts()

print(counts)
# {'00': 498, '11': 502}
# Qubits are perfectly correlated! (entanglement)
