The present application provides a method and device for encoding and decoding a set of point vector index representation strings and a unit base vector string without using a flag bit, but automatically alternating the encoding. When encoding and decoding each set of point vector index representation strings, a variable called string number and its syntax element, which indicates how many point vector index representation strings in the set, is first encoded and decoded; then the point vector index representation strings in the set are encoded and decoded one by one, and the encoding and decoding of a unit base vector string is automatically started, and the encoding and decoding of the point vector index representation strings and the unit base vector string are alternated continuously until all the strings in the current compression unit are encoded and decoded. In this way, each unit base vector string can save a flag bit, and the point prediction encoding efficiency is effectively improved.

A quantum computing demonstration device comprises a labyrinth model, the labyrinth model comprises path units, lamp bead units which are sequentially connected in series on the same path unit form lamp bead unit string groups, and the lamp bead unit string groups on the intersected path units are connected in parallel. When the switch is switched on, the first lamp bead unit on the path unit at the entrance of the labyrinth model is lightened, the lamp bead units connected in series subsequently are lightened in sequence, and the current at the tail end of the path unit is divided into two parts to lighten the lamp bead units on the crossed lamp bead unit string group. The labyrinth model is used as a demonstration device, the lamp bead units on all the path units are lightened at the intersection node positions of the path units at the same time, the process that the labyrinth model searches for an outlet is simulated, the demonstration speed of the labyrinth model for searching for the outlet is greatly increased, the parallel operation thought in quantum calculation is vividly simulated, and the calculation efficiency is improved. And the advantages of quantum computing are visually displayed to the public.
