An MIT research team has developed "encapsulation epitaxy," a technique for growing a monolayer superconductor within the sub-1-nm gap between graphene and a substrate, achieving an air-stable $\text{NbSe}_2$ thin film over one inch in size. This offers an atomic-scale solution to the area problem that has hindered miniaturization of superconducting quantum circuits.
AWS's Daniel R. Simon has proposed a quantum polynomial-time solution to DCP in a preprint. Any spillover to lattice problems depends on proof verification and resource estimates for standard parameters.
The world's first quantum-technology-integrated substation, now operating in Hefei, China, uses quantum sensors and quantum computing to detect minute grid anomalies and perform high-speed power flow calculations. With communication security also secured through quantum cryptography based on the laws of physics, it stands as an innovative proof-of-concept supporting next-generation power infrastructure.
A research team at the University of Tokyo cooled a nanoparticle levitated in vacuum down to near absolute zero and applied a "quantum quench," rapidly manipulating laser intensity. This technique circumvents the noise inherent in quantum mechanical zero-point fluctuations, achieving a 100-fold improvement in sensitivity for detecting minute accelerations.
A research team from IBM and the University of Chicago has developed a method that mathematically guarantees the correctness of computations impossible for classical computers. By embedding specific gates into error-detectable circuits, they succeeded in surpassing the limits of classical computation while obtaining highly reliable results.
Claude Mythos has accelerated known attacks against HAWK, a post-quantum signature candidate, and 7-round AES-128. Neither result affects cryptography in production use, but the work shows AI probing the mathematical structure of cryptographic schemes—shifting the bottleneck to human verification.
A research team led by the University of Michigan has developed a technology that controls the direction of electron motion using only quantum interference of light, without applying any voltage. By interfering two-photon and three-photon absorption pathways, they generated bullet-like currents unaffected by impurity scattering, and succeeded in freely changing the current's direction simply by manipulating the polarization of light.
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.
By harnessing a frustrated state in which electrons in a quantum material compete against one another, researchers have succeeded in controlling the electron arrangement—switching it from a stripe pattern to a checkerboard pattern—using only a minute magnetic field. This achievement points toward a path for developing next-generation computing and spintronic devices that operate with extremely low power consumption.
