Some quantum systems are so complex that even the most powerful supercomputers struggle to simulate their behavior. One solution is quantum simulation: building a controllable quantum system in the lab and tuning it to mimic the one researchers want to understand.

In optical fibers, chips and other light-guiding devices, minor defects can scatter photons and disrupt their path. A new study demonstrates a way to reveal properties which, in certain systems, help light wave behavior withstand such flaws. The method could help speed up the search for new kinds of electronics and optical technologies, and contribute to more reliable quantum devices.

Whether we are waiting for a car windshield to defrost in winter or a warm drink to cool down, how long it takes for an object to settle into a stable, even temperature within its environment (thermal equilibrium) depends on numerous factors. These can include surface area, the material properties of an object and airflow.

A research team at The Hong Kong University of Science and Technology (HKUST) has developed an Embodied Sensorimotor Robotic Arm (EmArm) capable of whole-arm tactile sensing and adaptive manipulation. By embedding a soft optical tactile skin directly into a robotic skeleton and integrating it with a real-time decision-making algorithm, EmArm can perceive and analyze contact information across its upper and lower arms, enabling human-like tactile perception and adaptive object manipulation.
