horizon memory

What did you create?
Horizon Memory is a physics-based simulation of quantum decoherence in the vicinity of a Reissner-Nordström black hole based on my previously published research. You can view a qubit being pulled into the black hole, with the live coherence decay expressed in a complex plane spiral graph where you can click the “Measure” button to stop the qubit in its journey at some cost.

What was difficult?
The most challenging bug I encountered was the race condition, where tapping the “Measure” button multiple times before the previous effect finished would lead to multiple timeouts trying to use the same variable simultaneously. Therefore, I managed to track down that bug early on by using the console and noting the trends.

What accomplishment are you most proud of?
The surface gravity is not represented using the slider but rather is output based on a real Reissner-Nordström horizon formula; plus, it takes into account the phenomenon known from the physics where we see κ heading toward zero when charge moving toward mass. This finding was drawn from my research, rather than an approximate assumption.
