Cambridge researchers used an ultracold potassium gas to simulate a relativistic quantum field and directly image the spatial fluctuations present in its ground state. By suppressing thermal noise below 6 nanokelvin, the team isolated fluctuations intrinsic to quantum mechanics itself, though important caveats about the method remain.
IMS's 'Shunkai' has begun operating with about 50 qubits. Being Japan's first isn't about scale—it's about integrating everything from software to the QPU, moving error-correction research onto real hardware.
MIT researchers have demonstrated a room-temperature source of correlated microwave signals by combining a magnetic thin film with a printed circuit board resonator. By exploiting the nonlinearity of magnets instead of superconducting circuits, the device could free quantum radar and noise-resistant communication from the constraints of ultracold cryogenics.
IBM cooled two connected modular cryostat cells to below 15 millikelvin simultaneously. Here's what the demonstration actually proves—and what remains unverified for long-distance quantum wiring and qLDPC implementation.
A team from the Max Planck Institute for the Science of Light and Harvard University used inverse-design algorithms to shrink wavelength demultiplexers, mode demultiplexers, and mirrors on silicon nitride photonic chips to as little as 1/500th the area of conventional designs, publishing the results in Nature Communications. To the researchers' knowledge, this is the first such demonstration on thick-film silicon nitride, opening a path toward integrated quantum photonics.
BTQ and ITRI verified QCIM for post-quantum cryptography in TSMC's 28nm design environment. Not an actual measurement of a completed chip, customer evaluations that BTQ expects by year-end mark the next hurdle for confirming performance.
A team led by Peking University has grown ABC-stacked rhombohedral graphene with over 99% phase purity, reaching up to 160×80µm. Practical use in quantum chips still requires larger-area growth and independent replication.
Eaton has secured $7 million from the US Air Force to develop a tool using Infleqtion's quantum computer to analyze simultaneous multi-failure scenarios on the power grid. The project tackles a combinatorial explosion of over 300 million possibilities through quantum computation.
The BESIII Collaboration analyzed 10 billion J/ψ decays and identified that the dominant constituent of X(2370) is a glueball. This result, confirming for the first time in half a century the existence of a particle composed solely of force-carrying particles, provides a direct low-energy test of the non-Abelian structure of QCD.
BQP and Modovolo have introduced a search engine that doesn't use quantum computers into the design of 3D-printed drone propellers. The improvement rate in actual performance and comparison conditions remain undisclosed, and verified figures are needed to evaluate commercialization.
