The Single-Spin Hologram In Quantum Information Holography, everything begins with one thing: a single spin of light—its angle and phase—copied across Planck-scale qubits. The singularity is the derivative: the source of changing phase, the “slope” of reality. The horizon is the integral: the sum over those slopes, an interference image that becomes the world you see. Each horizon pixel is a Bloch sphere. At every Planck tick, these pixels freeze a time-crystal frame, and the next frame renders
