Four Argonne scientists receive 2024 DOE Early Career Research Awards
As winners of the 2024 U.S. Department of Energy’s Early Career Research Program, four scientists from Argonne National Laboratory are each receiving an award of $550,000 a year for five years to help them answer complex questions.
Quantum error correction research reveals fundamental insights on quantum systems
New research has implications for fundamental science, quantum computing and future technological applications.
Nonreciprocal interactions go nonlinear
Using two optically trapped glass nanoparticles, researchers observed a novel collective Non-Hermitian and nonlinear dynamic driven by nonreciprocal interactions. This contribution expands traditional optical levitation with tweezer arrays by incorporating the so called non-conservative interactions.
Success Generating Two-Qutrit Entangling Gates With High Fidelity
Quantum information processors that operate with ternary logic (qutrits) offer significant potential advantages in quantum simulation and error correction, as well as the ability to improve specific quantum algorithms and applications. Building on previous R&D with qutrits at the Advanced Quantum Testbed (AQT), the paper’s experimental team, led by a promising UC Berkeley graduate student, successfully entangled two transmon qutrits with gate fidelities significantly higher than in previously reported works.
Breakthrough boosts quantum AI
A groundbreaking theoretical proof shows that a technique called overparametrization enhances performance in quantum machine learning for applications that stymie classical computers.
Quantum computer in reverse gear
Today’s computers are based on microprocessors that execute so-called gates. A gate can, for example, be an AND operation, i.e. an operation that adds two bits.
Study seeks to define quantum compression
A study led by Oak Ridge National Laboratory researchers identifies a new potential application in quantum computing that could be part of the next computational revolution.
Five Ways QSA is Advancing Quantum Computing
The Quantum Systems Accelerator has issued an impact report that details progress made since the center launched in 2020. Highlights include a record-setting quantum sensor that could be used to hunt dark matter, a machine learning algorithm to correct qubit errors in real time, and the first observation of several exotic states of matter using a 256-atom quantum device.
How to reverse unknown quantum processes
In the world around us processes appear to follow a certain time-direction: dandelions eventually turn into blowballs. However, the quantum realm does not play by the same rules. Physicists from the University of Vienna and IQOQI Vienna have now shown that for certain quantum systems the time-direction of processes can be reversed. This demonstration of a so-called rewinding protocol has been published in the Journal “Optica”.
UTEP to Build on Research Strengths with Brookhaven National Laboratory Partnership
The University of Texas at El Paso signed a memorandum of understanding with the U.S. Department of Energy’s Brookhaven National Laboratory to create new research opportunities for UTEP faculty and students as well as internship and employment opportunities in critical fields such as energy, data science and quantum information.
New Form of Universal Quantum Computers
Quantum bits (qubits) in a quantum computer serve as a computing unit and memory at the same time. Because quantum information cannot be copied, it cannot be stored in a memory as in a classical computer.
National Quantum Information Science Research Centers to Host Virtual Career Fair Sept. 14
UPTON, NY– After a successful first event, the U.S. Department of Energy Office of Science’s National Quantum Information Science (QIS) Research Centers are preparing for their second virtual QIS Career Fair, to be held on Sept. 14, 2022. The event aims to make undergraduate, graduate, and postdoc communities aware of the wide range of QIS careers they can pursue—from technical and scientific roles to positions that facilitate research and bring awareness to the field, in areas including communications, marketing, and human resources.

Scientists at Oak Ridge National Laboratory and the University of Nebraska have developed an easier way to generate electrons for nanoscale imaging and sensing, providing a useful new tool for material science, bioimaging and fundamental quantum research.
Grasshopper jumping on Bloch sphere finds new quantum insights
New research at the University of Warwick has (pardon the pun) put a new spin on a mathematical analogy involving a jumping grasshopper and its ideal lawn shape. This work could help us understand the spin states of quantum-entangled particles.
Creating the Heart of a Quantum Computer: Developing Qubits
To use quantum computers on a large scale, we need to improve the technology at their heart – qubits. Qubits are the quantum version of conventional computers’ most basic form of information, bits. The DOE’s Office of Science is supporting research into developing the ingredients and recipes to build these challenging qubits.
