Abstract
Systems and methods are provided for coordinating decisions between noncommunicating parties using quantum physics. The procedure includes recognizing and identifying features of a coordinating decisions between non-communicating parties (CDNP) problem, expressing these features in a precise and mathematical manner, finding a solution using quantum states and measurements, and physically implementing the solution. Since quantum mechanics can violate Bell inequalities, quantum solutions to a CDNP problem have advantages over non-quantum solutions.

A system for coordinating decisions, the system comprising:
- at least one processer;

- providing the quantum protocol to a first subsystem configurable to:
- obtain a first observation in the set of observations;
- select, according to the first mapping, a first set of measurement operators of the sets of measurement operators based on the first observation;
