PURPOSE: To provide a quantum device which can execute a complicated logical function with a single device, operates at a temperature higher than a room temperature, and can be programmed electrically to perform a plurality of kinds of logical operations in a binary or m-ary arithmetic circuit. CONSTITUTION: A multifunctional resonant tunneling logic gate incorporates a resonant tunneling transistor 12 having first, and second and third terminals. A plurality of signal inputs are connected to the first terminal of the transistor 12 through an adder 10 and a bias input gives a bias to the first terminal of the transistor 12 so that the transmission characteristic of the transistor 12 may be shifted relatively to the signal inputs. |
