Photodetectors are typically only sensitive to light within a certain narrow bandwidth, which causes numerous problems to product developers. Now, researchers have found a way to address this by treating an ordinary photodetector with UV light can turn it into a high bandwidth device.
A diagnosis of pancreatic cancer is often a death sentence because chemotherapy and radiation have little impact on the disease. But new research could eventually lead to a new type of treatment based on gold nanoparticles.
Scientists were able to produce subnatural-linewidth biphotons from a Doppler-broadened hot atomic vapour cell. This method marks a significant breakthrough in the field, as it greatly simplifies production process of narrowband biphotons.
Researchers have studied the interaction between microwave fields and electronic defect states inside the oxide layer of field-effect transistors at cryogenic temperatures. They found that the physics of such defect states are consistent with driven two-level systems possessing long coherence times, and that their induced dynamics can be coherently and independently controlled.
Scientists report the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
