The passage around this formula
The program first reproduces published overlap or decoherence curves inside their stated regimes. Only then does it calculate D , , , , and threshold times. A separate finite-time module approximates the admissible-future optimization needed for . Its result is labeled exploratory until it reproduces benchmark purification cases from the 2025 work.
Learn the underlying idea
A subscript is a label attached below a symbol. It often selects a time step, component, category, or member of a sequence.
