NIST has chosen a new algorithm for post-quantum encryption called HQC, which will serve as a backup for ML-KEM, the main algorithm for general encryption.

D-Wave Quantum Inc.(“D-Wave” or the “Company”), a leader in quantum computing systems, software, and services and the world’s first commercial supplier of quantum computers, today announced a scientific breakthrough published in the esteemed journal Science, confirming that its annealing quantum computer outperformed one of the world’s most powerful classical supercomputers in solving complex magnetic materials simulation problems with relevance to materials discovery. The new landmark peer-reviewed paper, “Beyond-Classical Computation in Quantum Simulation,” validates this achievement as the world’s first and only demonstration of quantum computational supremacy on a useful problem.

Rigetti Computing, Inc. , a pioneer in full-stack quantum-classical computing, announced today the public launch of its 84-qubit Ankaa-3 system. Ankaa-3 is Rigetti’s newest flagship quantum computer featuring an extensive hardware redesign that enables superior performance. Rigetti also celebrates major two-qubit gate fidelity milestones with Ankaa-3: successfully halving error rates in 2024 to achieve a median 99.0% iSWAP gate fidelity, as well as demonstrating 99.5% median fidelity fSim gates.

A research team at the Department of Energy’s Oak Ridge National Laboratory created a novel advanced microscopy tool to “write” with atoms, placing those atoms exactly where they are needed to give a material new properties.

In a study published online in Nature, a research team led by Prof. PAN Jianwei, Prof. CHEN Yuao, and Prof. YAO Xingcan from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences has, for the first time, observed the antiferromagnetic phase transition within a large-scale quantum simulator of the fermionic Hubbard model (FHM).

Berkeley Lab researchers demonstrate a programmable approach to fabricating optical qubits in silicon for large-scale manufacturing.

Rice University physicists have discovered a phase-changing quantum material — and a method for finding more like it — that could potentially be used to create flash like memory capable of storing quantum bits of information, or qubits, even when a quantum computer is powered down.

Nuclear spins in a crystal can be detected and manipulated through their interactions with the more accessible electron spin of a neighboring crystal defect. This strategy has enabled nanoscale magnetic resonance imaging and other quantum applications. But a long-standing challenge has been to target a specific nuclear spin, while protecting the delicate quantum nature of the electron spin. Important progress on this challenge has now been achieved by two teams at the Delft University of Technology in the Netherlands.

QuEra Computing hosted a competition to bring together STEM students with expertise in quantum computing and creative students skilled in digital media. Students in NYU Tandon’s Integrated Design & Media program contributed to projects judged to be among the best of the week.

A new study published in Nature Communications April 7 could reshape the future of magnetic and electronic technology. Scientists at Rice University have discovered how a disappearing electronic pattern in a quantum material can be revived under specific thermal conditions. The finding opens new doors for customizable quantum materials and in-situ engineering, where devices are manufactured or manipulated directly at their point of use.
