This paper compares the entanglement of two quanta using the conventional formulation of quantum mechanics and a time-symmetric formulation without collapse postulate. It explores discrepancies in the analysis of the Hanbury Brown–Twiss experiment, potential solutions to nonlocality and measurement problems, and addresses time asymmetries in the conventional formulation.
Heaney shows that a time‑symmetric, collapse‑free formulation reproduces all standard quantum predictions while providing a more symmetric ontological picture. The approach retains the familiar mathematics (the integrand is the same overlap of wavefunctions) but interprets it as a spacetime‑distributed transition density. This resolves several foundational puzzles (measurement collapse, arrow of time, retrodiction) and suggests new experimental checks on classic interference experiments such as HBT.
