𝐒𝐨𝐟𝐭 𝐠𝐨𝐥𝐝 𝐧𝐚𝐧𝐨𝐰𝐢𝐫𝐞𝐬 𝐜𝐚𝐧 𝐡𝐞𝐥𝐩 𝐢𝐦𝐩𝐫𝐨𝐯𝐞 𝐧𝐞𝐮𝐫𝐚𝐥 𝐢𝐧𝐭𝐞𝐫𝐟𝐚𝐜𝐞𝐬 Neural interfaces, which allow for information to be transmitted directly from the brain to a computer, are getting closer to becoming a reality and are no longer just a concept from science fiction films. However, there are still many challenges and limitations to creating biocompatible devices that are similar in properties to natural human nervous tissue. First and foremost, implantable electrodes need to be safe. They need to be made of inert materials that do not cause mechanical damage to nerve tissue. This is a challenge because hard metals are often used to create conductors, but softer silver devices can oxidize over time and release silver ions, which can be toxic in high concentrations. #archtown #innovation #nano #tech

In-vitro (meaning “in the glass” in Latin) is an approach to make biomedical studies outside a living organism, in the lab and in a controlled environment. On the other hand, the term 'In-silico' refers to a procedure performed via a computer simulation (the name originates from the computer microprocessors that were made of semiconductor silicon). In health care and medical research, 'in Silico' is used to refer to experiments that are carried out entirely on a computer. One challenge with In-vitro studies is that they do not exactly mirror the precise state of an organism since it is happening outside the organism. In-silico accounts for this by using models and complex networks to simulate experiments and make predictions. One unique aspect of the LIFESAVER Project is its combination of in-vitro and In-silico techniques.

*new paper* Continuing to break my tradition of not posting on preprints because of the significance of the results. In the wider body of research, we have been exploring the utilisation of photonic lanterns as an optical interface in quantum communications to perform multiplexing, increase photon-counting rate, and a couple of free-space signals to single-photon detectors. One of the work's results was this experiment, in which we showed that a multimode photonic lantern (made of four multimode graded-index fibres), along with four single-photon detectors, can reduce model dispersion and the spatial size of the spot on the active area of a single-photon detector, thus reducing the QBER associated with the timing jitter. The larger multimode photonic lantern input, which is easier to couple to, also helps reduce pointing and tracking requirements. While it requires four detectors per quantum state, the cost of silicon SPADs, typically used for free-space quantum communications, and time-tagging hardware is reducing. Cost savings in the pointing and tracking capabilities may balance out the cost of the additional detectors. We could also utilise our own patent in time-duplexing to reduce the number of detectors back to one for low rep rates. An added benefit is that using multiple detectors per state can decrease the impact of dead time for high clock rate and low loss scenarios.

Breakthrough in non-volatile photonic-electronic memory with thin-film ferroelectrics. Researchers develop a non-volatile photonic-electronic memory chip, combining ferroelectric materials and silicon for low-energy, high-speed data communication and neuromorphic computing. This achievement represents a major step toward realizing high-performance, low-energy photonic-electronic integrated systems. It provides a critical foundation for the development of photonic-electronic systems and is expected to drive innovation in next-generation data centers, high-speed communication networks, neural network computing, and high-performance computing. As integration improves and manufacturing processes mature, these chips are anticipated to become core components of future photonic-electronic systems, ushering in a new era for information technology - https://lnkd.in/gh5Q95CW #photonics

Quantum Locking: Unlocking Real-World Potential Quantum locking, also known as flux pinning, is a phenomenon where a superconductor, cooled to very low temperatures, locks a magnetic field in place, allowing an object to levitate and move without friction. This happens because of the formation of quantum vortices—magnetic field lines trapped within the superconductor—which keep the object fixed relative to the magnetic source. Applications in Everyday Life: 1. **Transportation**: Quantum locking is most promising in transportation, particularly in magnetic levitation (maglev) trains. By using superconductors, these trains can operate with near-zero friction, enabling higher speeds and lower energy consumption. Quantum locking could enhance the stability and efficiency of these systems, making public transport faster and safer. 2. **Medical Devices**: Quantum locking could advance medical technology, especially in MRI machines. Superconductors are already crucial in MRIs, and improvements in quantum locking could lead to more stable and efficient machines, offering clearer imaging and reduced costs. 3. **Quantum Computing**: Quantum locking may play a role in quantum computing by stabilizing qubit systems. These systems require highly controlled environments to function correctly, and quantum locking could help maintain the necessary stability, reducing external disturbances. 4. **Precision Measurement Tools**: Instruments like gravitational wave detectors and particle accelerators, which require extreme precision, could benefit from quantum locking. This could improve the accuracy and stability of such tools, allowing for more detailed exploration and measurement of the universe. While still in the developmental stage, the potential of quantum locking is vast and could revolutionize transportation, healthcare, and precision measurement by offering unprecedented control and stability. #### Hashtags: #QuantumTechnology #QuantumLocking #Maglev #QuantumComputing #Superconductors #FutureTech #Innovation #Science
