Hitachi and Intel have been selected as prospective contractors for a NEDO project, moving forward to develop a 100-qubit-class silicon quantum computer using the 18A-based process and a qubit PDK. The plan calls for integrated development of manufacturing, packaging, and cloud operation.
SAXON Q has begun taking orders for room-temperature 128- and 512-qubit machines. The new systems use a multi-core architecture with 8 or 16 qubits per core, with actual delivery and third-party verification standing as the next hurdles.
A critical interpretive blind spot has been discovered in the experimental scenario for "gravitationally induced entanglement," long regarded as decisive evidence for quantum gravity theory. An international research team centered at Kyushu University has mathematically proven that a quantum superposition of the gravitational field can be equivalently re-described—via a change of coordinate system—as a phenomenon of particles moving through a "classical gravitational field," fundamentally redefining the standard for such evidence.
Terahertz waves are valuable for imaging and high-speed communication, but the sheer size and cost of equipment have long blocked widespread adoption. A UCLA research team has developed a technology that repurposes quantum well structures—a standard building block in optical communications—to integrate the core functions onto a single chip, opening the door to dramatic system miniaturization and mass production.
A research team at Louisiana State University has developed a metacrystal with microscopic slits etched into a gold thin film, successfully controlling the quantum statistical properties of light at room temperature. This technology, which manipulates interference in multi-photon systems using a semiconductor-like band structure, could accelerate the practical implementation of quantum technologies.
BQP will develop orbital object classification AI under its first SpaceWERX contract. We examine the claimed 7,000x model compression, the undisclosed evaluation conditions, and how far the technology is from space-based demonstration.
The US Department of Energy has announced manufacturing technology for high-purity silicon and germanium gases that eliminate nuclear spins—a noise source in quantum computers—to an extreme degree. By completing the process from isotope enrichment to deposition-ready gases entirely within the United States, the effort aims to improve quantum device performance and strengthen the supply chain.
Australia's Q-CTRL announced that its quantum magnetic navigation system has passed DO-160 environmental qualification testing for aircraft. The device identifies current location by using minute variations in Earth's magnetic field as a fingerprint, taking a major step toward practical use as backup navigation when GNSS is jammed.
To correct drift in control parameters that occurs during quantum computation, a Google research team has developed a method that leverages quantum error correction detection signals for reinforcement learning. By using local error rates as a metric to autonomously adjust tens of thousands of parameters, continuous calibration becomes possible without ever halting computation.
A research group at the University of Tokyo has developed, for the first time in the world, a technology that reads and writes the magnetic information of a single atom using only quantum mechanical "force," without using any electric current whatsoever. Because this method can prevent heat generation from Joule heating as well as malfunctions, it represents a groundbreaking achievement toward realizing the ultimate high-density memory.
