For more than 60 years, many ternary or quaternary circuits have been proposed based on similar assumptions. We successively examine four of these assumptions and demonstrate that they are wrong. The fundamental reason for which m-valued combinational circuits are more complicated than the corresponding binary ones is explained. M-valued flash memories are used in USB devices because access times in not critical and a trade-off is possible between access time and chip area. If m-valued circuits are reduced to a very small niche in the binary world with semi-conductor technologies, there is a significant exception: quantum devices and computers are a true breakthrough as qbits are intrinsically multivalued. Successful m-valued circuits need m-valued devices as qbits.

A demonstration that e=2.718 rounded to 3 is the best radix for computation is disproved. The MOSFET-like CNTFET technology is used to compare inverters, Nand, adders, multipliers, D Flip-Flops and SRAM cells. The transistor count ratio between ternary and binary circuits is generally greater than the log(3)/log(2) information ratio. The only exceptions concern a circuit approach that combines two circuit drawbacks (an additional power supply and a circuit conflict between transistors) and only when it implements circuits based on the ternary inverter. For arithmetic circuits such as adders and multipliers, the ternary circuits are always outperformed by the binary ones using the same technology.

For more than 45 years, many multi-valued circuits have been presented. With very rare exceptions, they have been unsuccessful for fundamental reasons that can be explained. Each time a new circuit technology is presented, a lot of new MVL circuits are proposed. Can new circuit technologies overcome the fundamental disadvantages of MVL circuits? The evolution of IC technologies in the last decades unfortunately increases the disadvantage of MVL circuits versus binary ones. For non conventional technologies, only quantum devices look promising, even if implementation is challenging and applications are restricted to a small niche.
