Why trapped-ion quantum computing matters to investors
There are many types of competing quantum computing technologies right now, so it makes sense to pay attention to what is moving into more practical applications and where. Although still in development and possibly decades from having practical uses, trapped-ion quantum computers have one main advantage: They can operate at room temperature. Because they can be operated at room temperature, it may be easier to implement trapped-ion quantum computers in a wider range of facilities, since no special equipment will be needed to keep them supercooled.
They still have significant downsides, like their relative lack of speed compared to competitors, but for some applications, this won't matter. Regardless of your opinion on this emerging technology, quantum computing stocks should be approached as a long-term and highly risky investment, so go slow, choose your plays carefully, and plan to hold on to them for a decade or more to see what they become.
