“talking knots were recording devices fashioned from strings. The Inca people used them for collecting data and keeping records, monitoring tax obligations, properly collecting census records, calendrical information, and for military organization” (more about Quipu)
“we illustrate a step-by-step process for the design of a generic quantum computation device which implements a Turing-equivalent finite state machine capable of using superposition for all instructions, data, and state. In other words, it can execute completely separate branching instructions in quantum superposition.” (more about QQFSM — A Quantum Finite-State Machine).
Quantum knots — experimental observations of knots in quantum matter — knotted solitary waves, or knot solitons, in the quantum-mechanical field describing a gas of superfluid atoms, also known as a Bose–Einstein condensate.
