Researchers at UC Santa Barbara have successfully developed a quantum chip with von Neumann architecture.

Most quantum computing to date has been based on architecture that predates von Neumann.

Even there, though, during much of the history of computers, Von Neumann machines executed only one instruction at a time.

Hans Bethe believed that without John von Neumann, the development of modern computers would at best have been delayed ten years or more.

In his short life, von Neumann especially had many other interests, including work on quantum theory and the design of the first electronic computers.

Von Neumann was an American mathematician who, by coincidence, had also been born in Hungary and had attended the same school as Mr Harsanyi.

Unless you fancy using three different machines to run Word, Excel and PowerPoint, give credit to the fathers of Eniac, the first reprogrammable computer: John Mauchly, Presper Eckert and John von Neumann.
