MIT physicists have taken a key step toward solving the puzzle of what leads electrons to split into fractions of themselves. Their solution sheds light on the conditions that give rise to exotic electronic states in graphene and other two-dimensional systems. The new work is an effort to make sense of a discovery that was reported earlier this year by a different group of physicists at MIT, led by Assistant Professor Long Ju. Ju’s team found that electrons appear to exhibit “fractional charge” in pentalayer graphene — a configuration of five graphene layers that are stacked atop a similarly structured sheet of boron nitride.

IQM Quantum Computers (IQM), a global leader in designing, building, and selling superconducting quantum computers, today announced that its quantum cloud service IQM Resonance will be available to Oak Ridge National Laboratory (ORNL), the largest U.S. Department of Energy science and energy laboratory, for accelerating research.

In classical physics, complex systems eventually reach equilibrium (if you wait long enough, the ice always melts). However, certain quantum many-body systems defy this norm. For them, thermalization does not occur, and the system remains out of equilibrium. That is the case of a large class of strongly disordered systems —where features like particle interactions or individual energies exhibit a certain degree of randomness. This behavior is due to many-body localization (MBL), a mechanism that preserves the system’s initial conditions over time.

European scientists are using diamonds to build a new quantum computer that works without needing to be cooled to ultra-low temperatures. This technological approach promises to make quantum computers more practical and scalable, leading, for example, to faster development of life-saving drugs and more powerful optimisation algorithms in the finance sector.

Atlantic Quantum, in collaboration with Professor Kevin P. O’Brien at the Massachusetts Institute of Technology (MIT) Quantum Coherent Electronics (QCE) group, announces it has been selected by AFWERX for a Phase II STTR grant in the amount of $1.8 million focused on developing utility-scale superconducting quantum computers to address the most pressing challenges in the Department of the Air Force (DAF).

A research team led by physicists at the Department of Energy’s Pacific Northwest National Laboratory, in collaboration with colleagues at MIT’s Lincoln Laboratory, the National Institute of Standards and Technology, along with multiple academic partners, published their findings to assist the quantum computing community to prepare for the next generation of qubit development.

A €10m consortium funded by the European Commission and supported by the Quantum Flagship is using diamond and silicon carbide to build quantum computers and quantum simulators that can run at room temperature. The SPINUS project is developing quantum simulators with more than 50 qubits and quantum computers with over ten qubits, the team expects that their research will provide a strategy to scale up to over 1000 and 100 qubits, respectively, within five years post-project.

Rigetti Computing, Inc. (“Rigetti” or the “Company”), a pioneer in full-stack quantum-classical computing, today announced that Dr. Subodh Kulkarni, Rigetti CEO, will be delivering a keynote presentation at SEMICON Europa 2024 in Munich, Germany later today, November 13, 2024 at 2:45pm. Dr. Kulkarni will discuss the potential transformative power of superconducting quantum computing and how Rigetti is delivering hands-on access to state-of-art quantum hardware to enable research and innovation to continue to advance the industry.

In the QSolid collaborative project, Forschungszentrum Jülich and its partners have started operating the first prototype of a quantum computer with optimised qubit quality. It forms the basis of a future quantum computer being developed in Germany using superconducting qubits, which will be able to perform complex calculations for industry and research.

Rigetti, a pioneer in full-stack quantum-classical computing, announced the successful demonstration of real-time and low latency quantum error correction on a Rigetti quantum computer.
