"Design a modern and futuristic logo for a brand called 'Quantum Lightning' with the slogan 'Lightning Fast, Quantum Smart'. The logo should feature a stylized lightning bolt intertwined with a quantum circuit, symbolizing speed and intelligence. Use a sleek, metallic color palette with electric blue and silver tones. Incorporate subtle glowing effects to emphasize the energy and power of the brand. The slogan should be integrated seamlessly below the logo in a clean, contemporary font. The overall design should convey innovation, precision, and advanced technology."
