Scientists recently announced a major breakthrough in quantum communications. In a study published in Nature Communication, a team of researchers has demonstrated the transmission of a quantum key over a distance of 1 km, setting a new record. This could be a major step towards secure long-distance communications, in which the quantum key could be used to encrypt data.

The breakthrough is the result of utilizing a modified laser, which can be used to send a single photon from one point to another. This single photon is then used to create a quantum key, which is used to encrypt the data. The team was able to successfully transmit the quantum key over a distance of 1 km with a success rate of over 80%.

This discovery is a major step forward in the development of secure long-distance communications. It could potentially lead to a future where quantum keys are used to encrypt data, making it impossible for hackers to break into. This could have a huge impact on the security of data on the internet.
