Deep within solids, individual electrons zip around on a nanoscale highway paved with atoms. For the most part, these electrons avoid one another, kept in separate lanes by their mutual repulsion. But vibrations in the atomic road can blur their lanes and sometimes allow the tiny particles to pair up. The result is smooth and lossless travel, and it’s one way to create superconductivity.But...

Quantum Thermometer or Optical Refrigerator?Versatile optomechanical beams have potential applications in biology, chemistry, electronics.
- June 23, 2017
- Research News
In an arranged marriage of optics and mechanics, JQI-NIST physicists have created microscopic structural beams that have a variety of powerful uses when light strikes them. Able to operate in ordinary, room-temperature environments, yet exploiting some of the deepest principles of quantum physics, these optomechanical systems can act as inherently accurate thermometers, or conversely, as a...

Researchers have found that a small stretch is enough to unleash the exotic electrical properties of a recently discovered topological insulator, unshackling a behavior previously locked away at cryogenic temperatures.The compound, called samarium hexaboride, has been studied for decades. But recently it has enjoyed a surge of renewed interest as scientists ... Continue Reading
Lauren Aycock, a recent JQI graduate researcher, has been awarded a Congressional Science Fellowship from the American Physical Society.The fellowship, which lasts for one year, aims to provide members of Congress with the scientific and technical expertise of trained scientists. In turn, fellows like Aycock get to learn first-hand about public policy and communicate with Congress on behalf of... Continue Reading
Trapped ions and superconductors face off in quantum benchmark
The race to build larger and larger quantum computers is heating up, with several technologies competing for a role in future devices. Each potential platform has strengths and weaknesses, but little has been done to directly compare the performance of early prototypes. Now, researchers at the JQI have performed a first-of-its-kind benchmark test of two small quantum computers built from... Continue Reading

Shantanu Debnath is a graduate student in Chris Monroe's trapped ion quantum information group. He earned an undergraduate degree in engineering physics from the Indian Institute of Technology-Mumbai and afterward briefly studied the correlations that arise in 3- and 4-qubit entangled quantum states. As a PhD student at JQI, he has helped develop a 5-qubit trapped ion quantum computer that a user can program with any sequence of logic gates. This software-defined connectivity of many qubits opens up the possibility of executing large-scale quantum algorithms and simulations.
Stephen Eckel is postdoctoral researcher at the JQI, and a National Research Council postdoctoral fellow from 2013-2014. After receiving his undergraduate degree in physics at Lehigh University, he received numerous fellowships and prizes while pursuing a PhD in physics at Yale. There, he performed two precision measurements searching for the electron’s electric dipole moment, one using a solid-state sample and another using molecular lead-oxide. At JQI, he works with Gretchen Campbell on creating superfluid analogs of superconducting quantum interference devices (SQuIDs) using Bose-Einstein condensates of sodium atoms. He is currently working with a team of graduate students to build a new experiment that can incorporate both ultra-cold sodium and erbium.
Campbell is a NIST JQI fellow and works in the Laser Cooling and Trapping group. In her atom circuits lab, reserachers probe Na BECs in toroidal traps. The goals of these experiments include studying superfluidity, as well as superfluid analogs to superconducting circuits. A second experiment with ultracold strontium is being built. She received a Ph.D from MIT in 2006, where she worked with Wolfgang Ketterle and Dave Pritchard. There, she used Rb BECs in optical lattices to study atom interferometry, nonlinear atom optics and the superfluid – Mott insulator phase transition. These experiments included the first direct observation of the atomic recoil momentum in dispersive media. More recently, she worked with Jun Ye on precision measurements and frequency metrology with an 87Sr optical lattice clock.
Nicholas Grabon is a JQI graduate fellow who received an undergraduate degree in physics at the University of Wisconsin-Madison. There, he helped design silicon chips with embedded quantum logic. At JQI, he previously worked on the theory of topological states on a lattice containing individual sites. Now, he is working with Vladimir Manucharyan to build smaller resonators with higher quality, design (fluxonium) qubits with decreased noise and better understand many-body physics.
Aaron Lee, a JQI graduate student, received his undergraduate degree in physics at UMD. He worked with Chris Monroe’s trapped ion group, using ytterbium ions to simulate other quantum systems. As a graduate student, he has continued to study quantum information with the Monroe group and hopes his work can contribute to eventually building a quantum computer.
Alexey V. Gorshkov
Alexey Gorshkov is a JQI fellow and theoretical physicist at NIST. He attended Harvard for his undergraduate and graduate degrees, obtaining a physics PhD in 2010 studying under Mikhail Lukin. After that he was a postdoctoral fellow at Caltech, working with John Preskill. He won numerous university teaching and research awards during these years. His research is at the intersection of AMO physics, condensed matter physics, and quantum information science. He has authored dozens of papers and has a patent entitled: “Scalable Room Temperature Quantum Information Processor.”
