MIT Technology Review’s James O'Donnell delivered a thorough profile of PsiQuantum this week, focusing on the company’s efforts to raise operating temperatures for its equipment and on its supply-chain strategy. From the article:

“PsiQuantum’s bet is that this entire supply chain, byzantine as it might sound, will make the company more efficient than its competitors. That’s because, if you squint, it looks like a souped-up and high-precision version of the existing supply chain for silicon photonic chips, another type of technology that transmits information with light—one that’s already used in data centers. If PsiQuantum produces its chips at scale, it can take advantage of tools and infrastructure that already exist.”

Researchers from MIT Lincoln Lab and Caltech demonstrated a new quantum error-correction protocol in a single atomic ion. It reduces errors by about a factor of 2.2 and extends qubit lifetime by up to 1.5x compared with an unencoded qubit. “The approach is applicable to a range of finite-dimensional quantum platforms and could serve either as a component of larger error-correction codes or as a standalone strategy in few-qubit devices such as quantum network nodes,” the team said.

This work was published in Nature Communications.

IBM, Oak Ridge National Lab, and Cleveland Clinic announced that they calculated nine molecular configurations of a liquid salt that is a leading candidate material for extracting tritium fuel for fusion reactors. Solving this issue is a key element of the DOE’s Genesis Mission.
