摘要：
A quantum phase slip junction (QPSJ) based direct inverter gate is proposed in this article for the first time. The proposed inverter is simpler than the QPSJ-based inverter designed indirectly by using a two-input xor gate with specific input conditions. In the indirect inverter, one of the two inputs of the xor gate must be set to the clock pulse in order to perform the true inverter operation. However, the proposed direct inverter has only one input to which the input voltage can be applied directly, and therefore, it has a simpler structure with fewer elements that occupies less area on the chip. The true operation of the proposed inverter is verified by feeding its input with the standard pseudorandom binary sequence 3 and connecting its output to the next gate to test its ability for driving the next gate.
