Beijing, April 13, 2022 (Xinhua) -- Chinese scientists have designed a new quantum direct communication system with a hybrid encoding of phase quantum state and time-stamped quantum state, successfully realizing 100 km of quantum direct communication. This study shows that using the existing mature technology means, some scenes cannot be relayed quantum direct communication is feasible, such as satellite-ground quantum direct communication, point-to-point quantum direct communication between some cities, etc. It can reduce the number of trunks, reduce the cost of link nodes, reduce communication delay, and improve communication performance and user experience.

We are the professional manufacturer ,we have Fifty people's research and development team,and 100 people's sales team.

The mouse was invented in 1964 by DouglasEngelbart. Back then DouglasEngelbart worked at the Stanford Research Institute (SRI), an organization sponsored by Stanford University. Engelbart had long considered how to make a computer easier to run and how to replace the tedious instructions that had to be typed by a keyboard.

Ball mouse: rubber ball drive to light emitting diode and photosensitive triode crystal pulse signal sensor.
Photoelectric mouse: a light source pulse signal sensor with infrared scattering spot irradiation particle band light emitting semiconductor and photoelectric sensor.
Wireless mouse: The DRF technology is used to convert the mouse movement, button press or lift information on the X or Y axis into wireless signals and send to the host computer.
Mouse is a very common computer input device. It can locate the cursor on the current screen and operate the elements of the screen at the position of the cursor through the button and the scroll wheel device. The first mouse appeared in 1968, when American scientist Douglas Englebart made the first mouse in California.
According to its working principle, the mouse is divided into mechanical mouse and photoelectric mouse. The mechanical mouse is mainly composed of ball rolling, roller column and raster signal sensor. When you drag the mouse, it drives the roller to rotate, which in turn drives the roller column to rotate, and the raster signal sensor installed at the end of the roller captures the raster signal. The photoelectric pulse generated by the sensor reflects the vertical and horizontal displacement of the mouse, which is then processed and converted by a computer program to control the movement of the cursor arrows on the screen.
