Better defined signals from electron spins in special crystals
Spin qubits are promising for quantum science, but they can be hard to manipulate. Scientists have found that using a special type of crystal to host a certain qubit class — the triplet exciton — enables more control over the quantum state. Read More

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

Helium lifts new quantum computing concept
A team led by Jacob Covey, who is part of Q-NEXT and is an Associate Professor at the University of Chicago, laid out a new concept that could turn helium’s light weight into the next generation of quantum computers. The design relies on helium-3, an isotope with different quantum properties than the helium-4 used to cool MRI machines and fill party balloons. Once built, the computer could use high-powered lasers as “optical tweezers” to capture and control individual atoms of helium. Read More

Silicon Chip Offers New Way to Probe Quantum Materials in Strong Magnetic Fields
Scientists have created a silicon chip that can detect the electrical behavior of very small materials by using very high-frequency waves. The chip is made only from silicon and other non-superconducting materials and still performs very well when cooled from room temperature down to about 4 Kelvin. Read More
