Crucial Leap in Error Mitigation for Quantum Computers
Researchers at Lawrence Berkeley National Laboratory’s Advanced Quantum Testbed (AQT) demonstrated that an experimental method known as randomized compiling (RC) can dramatically reduce error rates in quantum algorithms and lead to more accurate and stable quantum computations. No longer just a theoretical concept for quantum computing, the multidisciplinary team’s breakthrough experimental results are published in Physical Review X.

U.S. Taxpayers Supply $2.7M to Dartmouth Engineering in the Name of Qubit Database Development
Funded by a new $2.7 million grant from the US Department of Energy (DOE), Dartmouth Engineering Professor Geoffroy Hautier will lead a three-year, multi-institutional effort to identify qbits, a basic unit of quantum information, in order to transform and advance quantum computing. The team aims to build a database of viable qbits, which can store information in their spin, by analyzing defects in solids.

U.S. Women of Quantum Computing Go Big
In the Computational Chemistry, Materials, and Climate (CCMC) Group at Lawrence Berkeley National Laboratory (Berkeley Lab), the future of quantum information science is being driven in part by a group of women scientists who see that future — and theirs along with it — as quite bright. Early in their careers and coming from a variety of academic fields, these women comprise more than half of the postdoctoral researchers in the group, a rarity in computing science. But if they have their way, gender parity in their field won’t be an oddity much longer.
U.S. Quantum Information Science Centers Already Producing Research Results
Quantum material’s subtle spin behavior proves theoretical predictions Spin chains in a quantum system undergo a collective twisting motion as the result of quasiparticles clustering together. Demonstrating this KPZ dynamics concept are pairs of neighboring spins, shown in red, pointing upward in contrast to their peers, in blue, which alternate directions.
