Quantum Reading
Natalia Morozova Painting
by Roberto Denti
From the reading of the title of the picture - "Entanglement between quantum and real spaces", the observer is encouraged to understand more the meaning and not to stop at a furtive, quick look. The question that arises is probably "what is this entanglement and what does it have to do with a semi-realistic picture"? I try to respond by degrees: entanglement is that particular phenomenon of quantum physics whereby if two particles came into contact, they remain in "communication" with each other even if placed at enormous distances from each other. This means that the quantum state of a physical system, in our case the two particles, cannot be described individually, but only as a superposition of multiple systems, each with its own characteristics.
