Guest Post In the second quarter, Brussels is expected to release the first draft for a Quantum Act, a document that should pave the way for Europe to become the leader in quantum technology. To stand a real chance against the US and China, the bloc must move beyond ambition and …

Insider Brief PRESS RELEASE — QpiAI, a leading developer of integrated AI and quantum solutions for enterprises, today announced a major advance in quantum error correction (QEC), unveiling a high-speed decoder hardware platform that dramatically reduces the time required t…

Insider Brief The quantum-safe cryptography ecosystem has expanded well beyond a handful of startups. Following NIST's finalization of post-quantum cryptography (PQC) standards in August 2024 and the selection of HQC as an additional algorithm in March 2025, organizations a…

Insider Brief PRESS RELEASE — Researchers at the Indian Institute of Science (IISc) have developed a technique to precisely manoeuvre quantum sensors through highly viscous biological environments, such as the interior of living cells, using magnetic microbots.

Insider Brief PRESS RELEASE — ANELLO Photonics, creator of the Silicon Photonics Optical Gyroscope (SiPhOG™), and Q-CTRL, the global leader in quantum infrastructure software, announce a strategic partnership for GPS-independent navigation for UAVs.

Insider Brief PRESS RELEASE — Fujitsu Limited and the Center for Quantum Information and Quantum Biology at The University of Osaka today announced the development of a new technology designed to accelerate the industrial application of quantum computers.

Insider Brief PRESS RELEASE — With the world's first scalable, fault-tolerant quantum computer expected to be years away, a group of New Zealand researchers has developed an exciting hybrid device that could solve big, intractable problems sooner.

Insider Brief Google Quantum AI, which was a pioneer in the superconducting approach to quantum computing, announced that it is expanding beyond that core approach to add neutral atom quantum computing, a move the company says will accelerate progress toward commercially useful machines.

Large-scale quantum computers are waiting in the wings. One of the main reasons we don't have them yet is because quantum hardware is so noisy. When it comes to computers, noise means errors that crop up when processing information.

A team of scientists led by the U.S. Department of Energy's Argonne National Laboratory has identified a rare, switchable quantum property in a new type of nickel sulfide material with applications in high-speed transistors and adaptive sensors.

An international research team led by scientists from Skoltech has developed a method to position molecules on the surface of ultrathin materials with unprecedented precision using molecular DNA self-assembly, enabling the creation of quantum light sources.

You may not be able to hear it, but all solid materials make a sound. Atoms bound in lattices of chemical bonds are never silent nor still — under the placid surface of each object, a low hum hovers or a high-energy squeak titters.

Gallium nitride, a semiconductor that can operate at high voltages, temperatures, and frequencies, has enabled technologies from LED lighting to high-power electronics. Now Cornell researchers have observed a quantum property of the material for the first time.

The performance of quantum computers could cap out after around 1,000 qubits, according to a new analysis published in the Proceedings of the National Academy of Sciences by Tim Palmer at the University of Oxford.

Quantum computers rely on qubits, the basic units of quantum information, which can exist in multiple states simultaneously. Researchers have now demonstrated a superconducting processor that works with dramatically reduced wiring complexity.

Physicists have directly visualized the fundamental electronic building blocks of flat-band quantum materials, a class of systems in which electron motion is effectively quenched and strong interactions give rise to emergent phases of matter.

A landmark result in quantum information theory demonstrates that all pure multipartite entangled states of qubits can be certified through device-independent self-testing protocols, advancing quantum cryptography and communication.

Researchers demonstrate universal logical operations in a silicon-based quantum processor, marking a significant step toward fault-tolerant quantum computing using industry-compatible semiconductor fabrication techniques.
