“There’s no road map,” said Michael Sipser, a veteran complexity theorist at the Massachusetts Institute of Technology who spent years grappling with the problem in the 1980s. “It’s like you’re going into the wilderness.”
It seems that proving that computational problems are hard to solve is itself a hard task. But why is it so hard? And just how hard is it? Carmosino and other researchers in the subfield of meta-complexity reformulate questions like this as computational problems, propelling the field forward by turning the lens of complexity theory back on itself.
Computer simulations confirm that the African Superplume causes the unusual deformations and rift-parallel seismic anisotropy detected below the East African Rift System.
Continental rifting involves a combination of stretching and fracturing that penetrates deep within the Earth, explains geophysicist D. Sarah Stamps. This process pertains to the elongation of the lithosphere, Earth’s rigid outer layer. As it becomes more taut, the lithosphere’s upper sections undergo brittle changes, leading to rock fractures and earthquakes.

Trinity’s quantum physicists in collaboration with IBM Dublin have successfully simulated super diffusion in a system of interacting quantum particles on a quantum computer.
This is the first step in doing highly challenging quantum transport calculations on quantum hardware and, as the hardware improves over time, such work promises to shed new light in condensed matter physics and materials science.
Not many pure-play quantum computing start-ups have dared to go public. So far, the financial markets have tended to treat the newcomers unsparingly. One exception is IonQ, who along with D-Wave and Rigetti, reported quarterly earnings last week. Buoyed by hitting key technical and financial goals, IonQ’s stock is up ~400% (year-to-date) and CEO Peter Chapman is taking an aggressive stance in the frothy quantum computing landscape where error correction – not qubit count – has increasingly taken center stage as the key challenge.
This is all occurring at a time when a wide variety of different qubit types are vying for dominance. IBM, Google, and Rigetti are betting on superconducting-based qubits. IonQ and Quantinuuum use trapped ions. Atom Computing and QuEra use neutral atoms. PsiQuantum and Xanadu rely on photonics-based qubits. Microsoft is exploring topological qubits based on the rare Marjorana particle. And more are in the works.
It’s not that the race to scale up qubit-count has ended. IBM has a 433-plus qubit device (Osprey) now and is scheduled to introduce 1100-qubit device (Condor) late this year. Several other quantum computer companies have devices in the 50–100 qubit range. IonQ’s latest QPU, Forte, has 32 qubits. The challenge they all face is that current error rates remain so high that it’s impractical to reliably run most applications on the current crop of QPUs.
Researchers have found a way to control the interaction of light and quantum ‘spin’ in organic semiconductors, that works even at room temperature.
Spin is the term for the intrinsic angular momentum of electrons, which is referred to as up or down. Using the up/down spin states of electrons instead of the 0 and 1 in conventional computer logic could transform the way in which computers process information. And sensors based on quantum principles could vastly improve our abilities to measure and study the world around us.
An international team of researchers, led by the University of Cambridge, has found a way to use particles of light as a ‘switch’ that can connect and control the spin of electrons, making them behave like tiny magnets that could be used for quantum applications.
Research is underway around the world to find alternatives to our current electronic computing technology, as great, electron-based systems have limitations. A new way of transmitting information is emerging from the field of magnonics. Instead of electron exchange, the waves generated in magnetic media could be used for transmission, but magnonics-based computing has been (too) slow to date.
Scientists at the University of Vienna have now discovered a significant new method. When the intensity is increased, the spin waves become shorter and faster—another step towards magnon computing. The results are published in the journal Science Advances.
Magnonics is a relatively new field of research in magnetism in which spin waves play a central role. A local disturbance in the magnetic order of a magnet can propagate as waves through a material. These waves are called spin waves, and the associated quasiparticles are called magnons. They carry information in the form of angular momentum pulses. Because of this property, they can be used as low-power data carriers in smaller and more energy-efficient computers of the future.
The physics of cell communication: ISTA scientists successfully model cell dynamics.
Like us, cells communicate. Well, in their own special way. Using waves as their common language, cells tell one another where and when to move. They talk, they share information, and they work together – much like the interdisciplinary team of researchers from the Institute of Science and Technology Austria (ISTA) and the National University of Singapore (NUS). They conducted research on how cells communicate – and how that matters to future projects, e.g. application to wound healing.
Biology may evoke images of animals, plants, or even theoretical computer models. The last association might not immediately come to mind, yet it is crucial in biological research. Complex biological phenomena, even the minutest details, can be understood through precise calculations. ISTA Professor Edouard Hannezo utilizes these calculations to comprehend physical principles in biological systems. His team’s recent work provides new insights into how cells move and communicate within living tissue.
Transparent Holographic video glass wall with 4k resolution. Glimm has made for one of her clients a transparent video wall called as well holographic video wall indoor with holographic content and video s for indoor location. The video wall exist of 8 panels of 55 inch TOLED displays which we have combined all together and hide the transformers and graphic cards in a small aluminium frame. The resolution is 4K and the display is of glass in the glass. Technology explaining : TOLED stands for Transparent Organic Light-Emitting Diode. It is a display technology that combines the benefits of both OLED (Organic Light-Emitting Diode) and transparent displays. In TOLED, each pixel of the display consists of a thin layer of organic materials that emit light when an electric current passes through them. These organic materials are sandwiched between transparent electrodes, typically made of indium tin oxide (ITO), which allow light to pass through. One of the key advantages of TOLED is its transparency. When the display is not actively emitting light, it appears transparent, allowing users to see through it. This property makes TOLED suitable for applications where transparency is desired, such as in heads-up displays, smart windows, or augmented reality devices or in retail designs, advertisement or create a large TOLED video wall or Hologram 2D 3D. TOLED also offers the benefits of OLED technology, including high contrast ratios, wide viewing angles, and fast response times. The organic materials used in TOLED displays can emit light directly, eliminating the need for a separate back lighting system, which contributes to their thin and lightweight design. Besides the Transparent OLED technology we produce as well Transparent LED displays or Transparent LCD displays. How to combine TOLED displays together? 1. Ensure compatibility: Make sure the Transparent OLED displays you are using are compatible with each other in terms of resolution, interface, and electrical requirements. 2. Physical alignment: Align the displays physically to create a larger display area. This typically involves arranging the displays side by side or in a grid formation. Use appropriate mounting brackets or frames to secure them in place. 3. Connection: Connect the displays together using the necessary cables or connectors. The specific connection method depends on the interface supported by the TOLED displays. Common interfaces include HDMI, Display Port, or other proprietary interfaces. 4. Synchronization: If required, synchronize the displays to ensure coordinated content across all the panels. This may involve configuring the displays through software or hardware synchronization methods. Consult the manufacturer’s instructions or documentation for guidance on synchronization options. 5. Display control: Depending on the setup and software capabilities, you may need to adjust display settings, such as resolution, refresh rate, or color calibration, to optimize the combined TOLED display. 6. Content management: Use appropriate software or programming techniques to distribute and display content across the combined TOLED displays. This could involve treating them as a single large display or as individual screens, depending on your requirements.
By following these steps, you can effectively combine multiple TOLED displays to create a larger and visually cohesive display area.
