A promising pairing: Scientists demonstrate new combination of materials for quantum science
Diamond and lithium niobate are often touted as high-performance quantum materials. Now scientists have combined the two materials as a single quantum device. In a study reported in ACS Photonics, researchers sent light from the diamond to the lithium niobate and measured the fraction of light that successfully made it across. The result: An extraordinary 92% of the light made the jump from diamond to lithium niobate. Read More

Researchers invent new way to stretch diamond for better quantum bits
A team of researchers at the University of Chicago, Argonne National Laboratory and Cambridge University have announced a breakthrough in quantum network engineering: By “stretching” thin films of diamond, they created quantum bits that can operate with significantly reduced equipment and expense. The change also makes the bits easier to control. The researchers hope the findings, published Nov. 29 in Physical Review X, can make future quantum networks more feasible. Read More

Chitambar group establishes criterion for nonlocal quantum behavior in networks
From the University of Illinois Urbana-Champaign: In a study published in Physical Review Letters, Q-NEXT thrust lead Eric Chitambar and Amanda Gatto Lamas adapt techniques from quantum computing theory to create a new classification scheme for quantum nonlocality. This not only allowed the researchers to unify prior studies of the concept into a common framework, but it facilitated a proof that networked quantum systems can display nonlocality only if they possess a particular set of quantum features.
