Proposal Shows How Noisy Qubits Might Correct Themselves

One of the chief obstacles facing quantum computer designers—correcting the errors that creep into a processor’s calculations—could be overcome with a new approach by physicists from and the California Institute of Technology, who may have found a way to design quantum memory switches that would self-correct. The team’s theory paper, which was published Dec. 8, 2020 in the journal Physical Review Letters, suggests an easier path to creating stable quantum bits, or qubits, which ordinarily are subject to environmental disturbances and errors. Finding methods of correcting these errors is a major issue in quantum computer development, but the research team’s approach to qubit... Continue Reading
Enhanced Frequency Doubling Adds to Photonics Toolkit

The digital age has seen electronics, including computer chips, shrink in size at an amazing rate, with ever tinier chips powering devices like smartphones, laptops and even autonomous drones. In the wake of this progress, another miniature technology has been gaining steam: integrated photonics. Photons, which are the quantum particles of light, have some advantages over electrons, the namesakes of electronics. For some applications, photons offer faster and more accurate information transfer and use less power than electrons. And because on-chip photonics are largely built using the same technology created for the electronics industry, they carry the promise of... Continue Reading
Kollár Receives Air Force Young Investigator Grant

JQI Fellow Alicia Kollár has been awarded a grant by the Air Force’s Young Investigator Research Program (YIP). She is one of 36 early-career researchers around the US to receive the three-year, $450,000 award. Continue Reading
Two JQI Fellows Named 2020 Highly Cited Researchers

Two JQI Fellows are included on the Clarivate Web of Science Group’s 2020 list of Highly Cited Researchers, which recognizes influential scientists for their highly cited papers over the preceding decade. The two researchers are Sankar Das Sarma, the Director of the Condensed Matter Theory Center and the Richard E. Prange Chair and Distinguished University Professor of Physics at the University of Marlyand (UMD), and Christopher Monroe, Distinguished University Professor and the Bice Zorn Professor of Physics at UMD and a Fellow of the Joint Center for Quantum Information and Computer Science.

PRB Highlights Work of Das Sarma and Hwang

To mark the 50th anniversary of Physical Review B, editors selected “milestone” papers that have made lasting contributions to condensed matter physics, including one co-written by JQI Fellow Sankar Das Sarma. Das Sarma wrote the selected paper, Dielectric function, screening, and plasmons in two-dimensional graphene, with Euyheon Hwang. Continue Reading
A Billion Tiny Pendulums Could Detect the Universe’s Missing Mass

Researchers at JQI and their colleagues have proposed a novel method for finding dark matter, the cosmos’s mystery material that has eluded detection for decades. Dark matter makes up about 27% of the universe; ordinary matter, such as the stuff that builds stars and planets, accounts for just 5% of the cosmos. (A mysterious entity called dark energy, accounts for the other 68%.) Continue Reading
PRA Highlights Work of JQI Fellow during 50th Anniversary Celebration

A paper coauthored by JQI Fellow Ian Spielman in 2011 has been highlighted by the journal Physical Review A as part of its 50th anniversary celebration—one of only 26 that the journal plans to highlight in its “anniversary milestones” collection.The collection comprises papers published in the journal “that have made important contributions to atomic, molecular, and optical physics and quantum information by announcing significant discoveries or by initiating new areas of research.” Highlighting these notable papers is part of the American Physical Society’s celebration of the splitting of the journal Physical Review into four journals, Physical Review A-D, that each...
