The researchers also used a two-qubit quantum algorithm to demonstrate the programmability of the cryogenic control chip. The Deutsch-Jozsa algorithm is one of the simplest and is much more efficient on quantum computers than classical computers.
This demonstrates the ability to program a control chip with an arbitrary sequence of operations and opens the way for on-chip implementations and truly scalable quantum computers.
Computers, in particular, need chips to increase processing power.
