Nanocomputer

A nanocomputer refers to a computer with molecular-sized switching elements, allowing it to be much smaller than in a conventional microcomputer.

Examples
Designs for mechanical nanocomputers which use single-molecule sliding rods for their logic have been proposed for use as controllers.

was cited for his work in dating back to 1959 where s could theoretically function as a form of nanocomputer. In January 2019, IBM introduced its quantum computer with a 20-  quantum processor. However, it is housed in a 2.7m glass cube which is needed to provide a controlled airtight environment.

Mobile devices, such as iPhones, have been thought of as nanocomputers as the fabrication process has been shrinking down below 5 s in size. Smaller Apple Watches have also created a new class of wearable devices.
