Discloses is an electronic device and a method for its operation. The device has first and second electrodes and an active material. The active material has selectable and stable first and second macroscopic quantum states, such as charge density wave ordered states, having respectively first and second values of electrical resistivity &#x3c1;and &#x3c1;at the same temperature. &#x3c1;is at least 2 times &#x3c1;. The method includes the step of switching between the first and second macroscopic quantum states by injection of current via the electrodes.

Switchable macroscopic quantum state devices and methods for their operation

The invention refers to an ultrafast quench based nonvolatile bistable device which consists of an active material on a passive or active substrate which changes its physical properties, after exposure to a sufficiently temporally short external perturbation causing an ultrafast quench. The perturbation can be from an external ultrashort laser pulse or ultrafast electrical pulse from an electrooptic device or any other generator of ultrashort pulses. This change of the materials properties can be detected as a change of optical properties or electrical resistance. The dielectric properties can be reverted back to their original state by the application of a heat pulse applied by an electrical heater within the device or an external laser.
