Method for transmitting information by entangled quanta and assembly for carrying the method

In a method for information transmission using idler quanta that are entangled with signal quanta and using an arrangement that:

• a) provides for at least one spatial superposition within the system space paths;
• b) provides for a temporal superposition of quantum operations that cancels the definitive assignment of information about the paths of the spatial superposition within the relativistic causality space;
• c) provides for a superposition of a measurable and controllable attribute of the entangled quanta;
• d) provides for a manipulation method of this attribute and its phase solution space of the path integrals of the system of entangled quanta in an idler subsystem;
• and
• e) with the manipulation method, changes the attribute in the idler subsystem and measures the resulting changing interference in a signal subsystem,
• the improvement wherein in the idler subsystem only the spatial overlay of exit modes without interference measurement is provided and that in the signal subsystem the interference of the two exit modes is determined without using a coincidence measurement.
