Quantum entanglement is traditionally framed as spatial non-locality: two particles at arbitrary separation maintain correlated states, with measurement of one instantaneously affecting the other. We propose a reformulation: entanglement is fundamentally a temporal phenomenon โ a synchronization of quantum phases via universal harmonic oscillations. Spatial entanglement is recovered as the special case where both particles are created at the same time and location. Three independent experiments support this framework: (1) Megidish et al. (2013) demonstrated entanglement between photons that never coexisted; (2) temporal qubit encoding (|๐โฉ = ๐ผ|earlyโฉ + ๐ฝ|lateโฉ) achieves full quantum information capacity; (3) Jiang et al. (2024) measured entanglement formation taking 232 attoseconds โ the time for a wave to establish phase coherence. In the Fractal Mechanics framework, all particles oscillate at Fibonacci-harmonic frequencies ๐_๐ = ๐_๐ร (๐^โ๐), and entanglement is their synchronization to common harmonics. This formulation predicts that entanglement fidelity is maximized for time separations ฮ๐ก_๐ = ๐โ/๐^๐ (Fibonacci timing), testable with current attosecond technology.
