HRL controls a silicon QPU configurable up to 18 qubits using 4K CMOS, running a distance-5 code on 7 qubits. By removing real-time control from room temperature, it takes on the wiring scaling wall.
Photon Queue has deployed its room-temperature quantum memory—a device that temporarily holds photons—at Sandia National Laboratories and the University of Maryland. A $4 million round will expand manufacturing and customer deployment.
AT&T has agreed to expand its use of D-Wave quantum computing, cutting an optimization process from roughly one hour to under 15 seconds. The next focus is verifying the impact on commercial networks and disclosing comparison conditions.
IBM has signed a definitive agreement to acquire HRL, jointly owned by Boeing and GM. The deal brings in spin qubits and cryogenic control, expanding manufacturing capabilities beyond the superconducting approach.
Fudan University has demonstrated a two-dimensional memory device that reads the presence of a single electron at room temperature as a 0.5V non-volatile threshold shift. While this reaches the physical limit on charge count, connecting it to high-capacity chips will require verifying retention and endurance across arrays.
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.
Acoustic chips have enabled miniaturization by converting radio waves into sound, but they faced a fundamental limit: applying high power caused vibrations that severed the wiring. The Hong Kong University of Science and Technology has overturned a half-century-old assumption by sealing the surface with a special layer to disperse stress, achieving 12 times the power tolerance of conventional designs and opening the door to direct satellite communication from smartphones.
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.
Interlune has announced that it produced 99% pure helium-3 from commercial-grade helium. Scaling up supply still requires demonstrated recovery rates, throughput, and manufacturing costs at liquefaction plants.
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.
