NIST researchers are developing a new method to connect quantum computers using silicon color centers, specifically focusing on W and G variants that emit light compatible with telecommunications. This work aims to create electrically driven light sources that act as bridges between stationary quantum processors and flying light signals. The initiative is currently in the research and development phase, with teams synthesizing these defects in silicon and integrating them into light-emitting devices and structures that boost light collection.
The potential impact is significant, as this technology could enable long-range quantum communication by converting electron spin information into optical signals. While current progress involves creating and testing these devices at very cold temperatures, the goal is to establish a reliable method for standardizing quantum connections. Implementation is a long-term effort, with ongoing work focused on improving the precision of defect placement and increasing the efficiency of light collection for future quantum networks.
