In November 2008, Queen Elizabeth II posed the famous question at the London School of Economics: Why did nobody see the crisis coming? This inquiry laid bare the recurrent failures of mainstream macroeconomics. From the Great Depression, the stagflation of the 1970s, the global collapse in 2008, to the subsequent pandemic shocks and inflation volatility, the Dynamic Stochastic General Equilibrium (DSGE) framework rests on premises of linear causality, representative agents, stable equilibrium, rational expectations and observer neutrality. It treats the economy as a clockwork machine driven solely by exogenous shocks, rendering it inherently incapable of capturing genuine uncertainty, mutually entangled expectations, and financial systems with cascading nonlinear breakdown transmission. This monograph is the first work worldwide to systematically establish quantum macroeconomics. Before decisions are made, expectations and plans coexist as superpositions of multiple possible states; observation, forecasting or policy intervention collapses these superpositions into definite outcomes. Households, firms, banks and nation-states are mutually entangled: the state of one agent forms an intrinsic component of another's state, and shocks propagate in a nonlocal manner. Coherence amplifies booms and panics, while the loss of coherence triggers phase transitions between booms, recessions and crises. Classical economics is subsumed as a decoherent special case where interference vanishes, representing a sublation that preserves the valid components of the conventional framework.
