Scientists from the Niels Bohr Institute of the University of Copenhagen in Denmark have developed a unique device capable of storing light in the form of sound, which opens up new perspectives for the quantum internet. This device, called a quantum drum, could become a key component of the future quantum internet, where the speed and security of data processing reach extremely high levels.
The quantum drum is a small ceramic membrane with special patterns of holes on the edges that vibrates when laser light hits it. These vibrations are converted into sound that can be stored and broadcast. This process allows the quantum drum to serve as a quantum memory, storing data without loss and with low noise.
According to the researchers, the new technology can significantly increase the storage time of quantum data. up to a record 23 milliseconds. This expands the potential for quantum networks, where storage and information need special accuracy and speed.
Quantum Internet based on such technologies promises a revolution in data transmission, as it reduces the need for  the use of amplifiers, which are necessary in optical fiber networks. This ensures less interference and greater security, as quantum data is difficult to intercept and change without disrupting its state.
Earlier it became known that scientists from Oxford University have developed an innovative method that allows millions of users get access to quantum computing. A technology called "blind quantum computing" works on the basis of existing optical fiber systems and can provide a secure connection with quantum computers.
