Modelling quantum register disentanglement

Abstract

Implementing quantum-inspired algorithms on classical computers suffers trade-off between the necessity of saving operational memory and the amount of memory necessary to fully represent a quantum state with possible entanglement. The latter is well known to consume the memory exponentially in the number of qubits. This paper sketches out the idea on how to reduce significantly the amount of necessary memory while distorting the entanglement moderately or not at all. At present, considered are real nonnegative probability amplitudes.
