| Description: | The electrical switching between macroscopic quantum states in 1T-TaS2 is presented according to the principle observed at fast laser switches in the same material. It is based on the findings that switching between macroscopic quantum states with sufficient differences in electrical resistance is surprisingly possible with the introduction of electric current. Switching devices based on macroscopic quantum states have a first and a second electrode and an active material, the active material has an optional and stable first and second macroscopic quantum state with a first and a second value of electrical resistance at the same temperature. Below a temperature of 180 K, the active material is in a commensurable (C) insulator state, from which it passes into a hidden quantum state (H – hidden) with the supplied electric current (writing W – write), which leads to a change of states and electrical resistance. The conditional reading step (R – read) can determine the resistance of the active material, and the erasing step (E – erase) returns the active material back to the first or second quantum state with a higher resistance with a longer current shock. |
