The best of both worlds: how to solve real problems on modern quantum computers

Argonne National Laboratory
July 11, 2019

In recent years, quantum devices have become available that enable researchers — for the first time — to use real quantum hardware to begin to solve scientific problems. However, in the near term, the number and quality of qubits (the basic unit of quantum information) for quantum computers are expected to remain limited, making it difficult to use these machines for practical applications.A hybrid quantum and classical approach may be the answer…

Predicting material properties with quantum Monte Carlo

Argonne National Laboratory
July 9, 2019

Recent advances in quantum Monte Carlo (QMC) methods have the potential to revolutionize computational materials science, a discipline traditionally driven by density functional theory (DFT). While DFT provides convenience to its practitioners and has unquestionably yielded a great many successes throughout the decades since its formulation, it is not without shortcomings…

Scientists combine light and matter to make particles with new behaviors

University of Chicago
July 3, 2019

Every type of atom in the universe has a unique fingerprint: It only absorbs or emits light at the particular energies that match the allowed orbits of its electrons. That fingerprint enables scientists to identify an atom wherever it is found. A hydrogen atom in outer space absorbs light at the same energies as one on Earth…

U.S. Department of Energy Renews Midwest Integrated Center for Computational Materials

Argonne National Laboratory
June 28, 2019

The U.S. Department of Energy (DOE) has announced that, over the next four years, it will invest $32 million to accelerate the design of new materials through use of high-performance computing. Seven projects separately led by three national laboratories and four universities will be developing open-source software for design of new materials based on DOE’s current leadership class and future exascale computing facilities.

The race to develop quantum technology is getting crowded

June 24, 2019

Quantum mechanics looks at how particles smaller than atoms interact. At this minuscule scale, entirely different laws of physics apply. But in the global race to develop quantum technology, the U.S. is competing in an increasingly crowded field. NewsHour Weekend’s Christopher Booker reports

The young physicist creating matter from light
June 21,2019

Growing up, Jonathan Simon loved playing Dungeons & Dragons — but not because the game involved elves, orcs or other fantastical creatures. It was all about the dice: Rolling them determined the outcome of every action. “What I thought was cool was that someone had gone through the effort of making rules to determine how a universe worked,” he says.

You’ve conquered the escape room. But can you escape the lab?

New York Times
May 4, 2019

URBANA, Ill. — It was 10 p.m., and we were locked in a room at the mall.It had been a long day. I had woken up at 5 that morning to finish writing an article. Then I had spent a day talking to University of Illinois students and professors. The physics department had invited me and two other science writers to visit, part of an effort to…

Cold atoms act as messengers at a distance

Particles can interact directly by repelling or attracting each other. But how do particles that are far apart interact? In a paper published by Nature on April 3, researchers at the University of Chicago report that atoms can exchange information using intermediary particles. This is the first time the phenomenon has been observed…

Researchers use light to create a one-way street for mechanical energy

Is it possible to create a “one-way street” for mechanical energy that only allows heat and sound to flow in one direction? In most standard set-ups, this is impossible: if acoustic energy can flow in one direction, then it can also flow in the reverse direction. Finding new ways to break this basic symmetry has sparked the interest of…
