Researchers at the Niels Bohr Institute at the University of Copenhagen have developed a new quantum memory device that could revolutionize the way data is stored and transmitted, leading to an ultra-secure and faster Internet. This device is a small drum, visible to the naked eye, that can reach quantum states and store data sent with light in its sonic vibrations.
The quantum drum is made of a glass-like ceramic material with holes scattered in an orderly pattern along its edges. When hit with laser light, it vibrates so quickly that quantum mechanics come into play, opening up possibilities for quantum technology. The drum can store quantum data emitted as light signals from a quantum computer, converting them into sonic vibrations and then resending them when needed.
In a recent study published in Physical Review Letters, researchers demonstrated that the drum can remain in a fragile quantum state, making it a key component for the quantum computer network of the future. This breakthrough in quantum memory could pave the way towards a more secure Internet with incredible speeds.
