Across various fields, from spatial mapping for reconnaissance and construction to facial recognition, virtual and augmented reality and autonomous driving, accurate 3D representation of dynamically evolving environments is paramount for safe human-machine interaction. Therefore, substantial research efforts are directed towards developing a cost-effective, high-performance and scalable 3D imaging sensor comparable with a CMOS camera.

Infinera Corp., a Nokia subsidiary, purchased the 82,000-square-foot facility at 6373 San Ignacio Avenue for nearly $27 million. The team will convert this former headquarters in South San Jose into a dedicated photonic semiconductor fabrication plant.

Light-based internet provider Taara, which spun out of Alphabet's "moonshot" incubator last year, just launched Taara Beam to provide 25Gbps connectivity within cities over invisible beams of light - line of sight permitting. Unlike last year's Taara Lightbridge, which connects communities separated by water and mountains at distances up to 20km (over 12 miles), the shoebox-sized Beam can be mounted to street poles and roof tops for city-wide connectivity at distances up to 10km. The 8kg (less than 20 pounds) device typically consumes about 90W.

Here we addressed this challenge by incorporating an intrinsically stretchable exciplex-assisted phosphorescent (ExciPh) layer. The elastomer-tolerant triplet-recycling mechanism mitigates exciton energy transfer limitations arising from the insulating elastomer matrix, yielding a light-emitting layer with more than 200% stretchability and an external quantum efficiency (EQE) of 21.7%. To translate this performance to fully stretchable devices, we integrated MXene-contact stretchable electrodes (MCSEs), which feature high mechanical robustness and tunable work function (W

NIST has developed a chip that reliably emits a single photon on demand. This ability will improve the efficiency of QKD (quantum key distribution) as we prepare for the arrival of quantum computers. Quantum computers will upend current cryptology by using Shor's algorithm to rapidly negate the current public/private key secure encryption methods. This has largely been solved by NIST's post quantum cryptology (PQC) algorithms.

We demonstrate how the apparent magnetic field induced lattice and CDW intensity change can be explained as a consequence of two independent experimental artifacts: a reconfiguration of atoms at the STM tip apex that alters the amplitudes of CDW modulations, and piezo creep, hysteresis and thermal drift, which artificially distort STM topographs.

Qunnect and Cisco have unveiled what they say is the first entanglement-swapping demonstration of its kind over deployed metro-scale fibre using a commercial quantum networking system. The demonstration combined Qunnect's room-temperature quantum hardware with Cisco's quantum networking software stack. The net result of the project is regarded by the partners as being able to bring practical quantum networks closer to scalable deployment, validating a spoke-and-hub model for scaling quantum networks through commercial datacentres.

This happened in the early 1990s, when I was a young engineer starting an internship at one of the companies that helped create the smart card industry. I believed my card was secure. I believed the system worked. But watching strangers casually extract something that was supposed to be secret and protected was a shock. It was also the moment I realized how insecure security actually is, and the devastating impact security breaches could have on individuals, global enterprises, and governments.

Can quantum physics enable better, cheaper, faster satellite photos? In a month or two, a startup will test a "quantum camera" for space-based imaging. If it works, it could slash the cost of missile defenses and give smaller NATO allies and partners spy-satellite capabilities that were once exclusive to major powers.
