By increasing the number of degrees of freedom one can reduce overall number of devices required to perform logic operations. Here, Zhao, Zheng, Wang et al demonstrate a device using current direction, a vector property, allowing for the implementation of Boolean logic, including IMPLY in a single device, and further enabling the construction of a full adder with only two devices.
