The cover features a deep indigo background symbolizing the mysterious and profound nature of quantum mechanics. At the center, there's an abstract, glowing graphic representation of the cesium atom's transition frequency spectrum, with radiating waveforms in vibrant blues and purples. Below it, a simplified diagram representing the Josephson Effect Voltage Standard is engraved in a fine golden outline, while on the bottom right corner, a visual depiction of the Quantum Hall Effect with stylized electric resistance loops in white and silver can be seen. Overlaying these visuals are soft, glowing gridlines that convey a sense of precision and measurement. Subtle mathematical formulas related to measurement uncertainty and quantum mechanics are embedded faintly in the background for added depth.

The book title is rendered in a clean and modern sans-serif font (e.g., "Avenir Next"), bold and in white, placed above the glowing cesium atom graphic. The subtitle, if required, is written in smaller text beneath the main title and in a matching sans-serif typeface. The author's name, "Zhenhui DU," is displayed at the bottom right in a classic serif font (e.g., "Garamond") for contrast and a degree of formality.

Title at the top center, followed by the graphical centerpiece of the cesium atom spectrum. The subtitle (if applicable) is smaller and positioned directly below the title. Key quantum standard visuals like the Josephson device diagram and Quantum Hall Effect representation are placed towards the lower half of the cover. These elements are evenly spaced to maintain balance, with formulas integrated seamlessly in the background. The author's name appears at the bottom right in a smaller size and with spacing from the edge for a clean look.
