Quantum computing researchers at Northwestern University report a new take on quantum compilers helped improve the efficiency and reliability of “chiplet-based” modular quantum computers.

Although it sounds like something that might be in a bag next to the pretzels at your next party, chiplets are, in fact, an intriguing approach to building quantum computers. As we’ll discover later, they are small, modular pieces of a computer processor that are designed to function as a building block for creating larger, more complex chips.

In a recent study posted on arXiv, a team of Northwestern University researchers report their Stratify-Elaborate Quantum Compiler (SEQC) boosts circuit fidelity by up to 36% and speeds up compilation by 2 to 4 times compared to existing tools, addressing critical scalability challenges in this emerging era of chiplet-based quantum systems.
