IT FROM QUBIT

The deep Newman-Penrose spin-frame structure of Wheeler-Feynman ---> Hoyle-Narlikar ---> Cramer ---> Aharonov-Vaidman

There are two kinds of Wheeler-Feynman QUBITs - advanced back from the future (support on local past light cone of emitter) & retarded past to future (support on future light cone of the emitter). Einstein's IT geometrodynamic field is an entangled 4 QUBIT STRING (In sense of quantum information theory) - note each term in the gravity metric tensor is a quartic product of advanced with retarded qubits -- similarly on the quadratic null light cone tetrad level.
