SUTD scientists developed a novel CMOS-compatible, slow-light-based transmission grating device for the dispersion compensation of high-speed data, significantly lowering data transmission errors and paving the way for on-chip integration. Fibre optics is now the fastest and most reliable technology to deliver internet connection. Data is transmitted through fast-travelling pulses of light that bounce off the walls of the fibre cables to allow the signal to travel further with less attenuation. However, fibre data transmission is subject to dispersion, or signal…
A system using photonics-based synthetic dimensions could be used to help explain complex natural phenomena. Scientists have made an important step toward developing computers advanced enough to simulate complex natural phenomena at the quantum level. While these types of simulations are too cumbersome or outright impossible for classical computers to handle, photonics-based quantum computing systems could provide a solution. A team of researchers from the University of Rochester’s Hajim School of Engineering & Applied Sciences developed a new chip-scale optical quantum…

By partnering, RPI’s…
Quantum computing could revolutionize our world. For specific and crucial tasks, it promises to be exponentially faster than the zero-or-one binary technology that underlies today’s machines, from supercomputers in laboratories to smartphones in our pockets. But developing quantum computers hinges on building a stable network of qubits — or quantum bits — to store information, access it and perform computations. Yet the qubit platforms unveiled to date have a common problem: They tend to be delicate and vulnerable to outside…
The novel device could lead to more versatile quantum processors with clearer outputs. What good is a powerful computer if you can’t read its output? Or readily reprogram it to do different jobs? People who design quantum computers face these challenges, and a new device may make them easier to solve. The device, introduced by a team of scientists at the National Institute of Standards and Technology (NIST), includes two superconducting quantum bits, or qubits, which are a quantum computer’s…
The new exascale machine is one step closer to enabling transformative science. The installation of Aurora’s 10,624th and final “blade” marked a major milestone for the highly anticipated exascale supercomputer at the U.S. Department of Energy’s (DOE) Argonne National Laboratory. After years of diligent work and planning, the system now contains all the hardware that will make it one of the most powerful supercomputers in the world when it is opened up for scientific research. Built by Intel and Hewlett Packard Enterprise (HPE), Aurora…
VIT team presents paper at CVPR 2023. A paper by researchers from the Vision and Imaging Technologies (VIT) department of Fraunhofer Heinrich Hertz Institute (HHI) has been accepted at the CVPR 2023 Workshop for Event-based Vision. The world-renowned workshop covers novel event-based cameras and algorithms that are significantly more energy-efficient, light-sensitive, and dynamic than conventional cameras. The paper, “X-maps: Direct Depth Lookup for Event-based Structured Light Systems” examines the use of event-based cameras to minimize latency in mixed reality environments…
The backbone of the internet is formed by a dense network of fibre-optic cables, each of which transports up to more than 100 terabits of data per second (1 terabit = 1012 digital 1/0 signals) between the network nodes. The connections between continents take place via deep sea networks – which is an enormous expense: a single cable across the Atlantic requires an investment of hundreds of millions of dollars. TeleGeography, a specialised consulting firm, announced that there currently are…
– reliable and real-time thanks to Artificial Intelligence. What about predicting with high certainty whether a component meets the quality requirements even while a machining step is in progress? Artificial Intelligence (AI) makes it possible. The AI solutions developed at Fraunhofer IWU represent an improvement over previous in-line inspection systems, eliminating the need for time-consuming removal for testing purposes. Such quality forecasts during processing can be integrated into many industrial manufacturing processes, often in combination with existing, cost-effective sensors. However,…

Robots able to accomplish tasks after watching people perform them in any environment. New work from Carnegie Mellon University has enabled robots to learn household chores by watching videos of people performing everyday tasks in their homes. The research could help improve the utility of robots in the home, allowing them to assist people with tasks like cooking and cleaning. Two robots successfully learned 12 tasks including opening a drawer, oven door and lid; taking a pot off the stove;…
Quantum technology is expected to fundamentally change many key areas of society. Researchers are convinced that there are many more useful quantum properties and applications to explore than those we know today. A team of researchers at Chalmers University of Technology in Sweden have now developed open-source, freely available software that will pave the way for new discoveries in the field and accelerate quantum research significantly. Within a few decades, quantum technology is expected to become a key technology in…
Spin-squeezed atoms used to improve quantum measurements. Although today’s best optical atomic clocks can be used to make extremely precise measurements, they are still limited by the noise from the spin statistics of the many atoms they interrogate, known as quantum projection noise (QPN). But by leveraging the truly quantum nature of these systems, it is possible to entangle the atomic sample to circumvent this QPN limit. Now, researchers have reported the first direct observations of an optical-lattice clock operating…
Terahertz-to-visible light conversion for future telecommunications. A study carried out by a research team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the Catalan Institute of Nanoscience and Nanotechnology (ICN2), University of Exeter Centre for Graphene Science, and TU Eindhoven demonstrates that graphene-based materials can be used to efficiently convert high-frequency signals into visible light, and that this mechanism is ultrafast and tunable, as the team presents its findings in Nano Letters (DOI: 10.1021/acs.nanolett.3c00507). These outcomes open the path to exciting applications in…

A new AI-based approach for controlling autonomous robots satisfies the often-conflicting goals of safety and stability. In the film “Top Gun: Maverick,” Maverick, played by Tom Cruise, is charged with training young pilots to complete a seemingly impossible mission — to fly their jets deep into a rocky canyon, staying so low to the ground they cannot be detected by radar, then rapidly climb out of the canyon at an extreme angle, avoiding the rock walls. Spoiler alert: With Maverick’s help, these…
