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

Turning a million-qubit quantum computing dream into reality
From The Next Platform: Earlier this year, Intel announced that it had successfully fabricated more than 10,000 arrays, each with three to 55 quantum dots, on a 300-millimeter wafer with a yield higher than 95%. Q-NEXT collaborator James Clarke, director of quantum hardware at Intel, says the feat was made possible thanks to the fact that Intel, unlike most other companies pursuing quantum, runs its own fabs, which the company also used to manufacture the control logic needed that allows such a high density of qubits.

U of C researchers make quantum breakthrough
From Crain's Chicago Business: University of Chicago researchers say they’ve made a breakthrough that might help bring quantum computing closer to reality. Researchers achieved a record time for memory, or “coherence,” in quantum bits, or qubits, of more than 5 seconds. Scientists are trying to harness quantum mechanics for the next generation of computing. One of the challenges is that particles maintain their quantum states, and their ability to store information, only briefly. Read More
