The Quantum Crystal Communicator harnesses the power of quantum crystal communication, allowing users to converse in real-time over interdimensional streaming video with a version of themself in another quantum timeline. In other words, the crystal allows you to speak with another you—one who made different decisions. Always wondered what your life might’ve amounted to if you’d taken a different fork somewhere along the way? What might your life have been like if you’d studied science instead of art, or married your High School crush, or been born into a better or worse situation? The quantum communication crystal allows you to find out! The objects are based on the Plaga Interworld Signaling Mechanism prisms found in Ted Chiang’s short story “Anxiety is the Dizziness of Freedom” in which a group of addicts become addicted to speaking with their quantum selves.

“Every prism — the name was a near acronym of the original designation, “Plaga interworld signaling mechanism” — had two LEDs, one red and one blue. When a prism was activated, a quantum measurement was performed inside the device, with two possible outcomes of equal probability: one outcome was indicated by the red LED lighting up, while the other was indicated by the blue one. From that moment forward, the prism allowed information transfer between two branches of the universal wave function. In colloquial terms, the prism created two newly divergent timelines, one in which the red LED lit up and one in which the blue one did, and it allowed communication between the two.”
