Toshiba is currently working on its new quantum internet. Here’s why some experts are getting crazy about its latest dual-band stabilization method.
Toshiba is one of the leading PC or Laptop manufacturers in the world. Aside from laptops, this giant tech developer can also provide high-end products such as the Toshiba 50-inch Smart 4K TV, Toshiba Smart WiFi Purifier, and other tech devices that can make your life enjoyable and easier.
And now, Toshiba confirmed that it will join the giant internet providers after it announced that its team of developers is now working to make quantum internet a possibility. Experts claimed that this new connectivity can offer a better internet connection compared to the current 5G and the upcoming 6G services.
Toshiba said that it will do this through its latest dual-band stabilization method. The tech giant company confirmed that this innovation allowed it to achieve more than 600 km of quantum communication distance.
Engineers at the Cambridge Research Laboratory of Toshiba Europe have demonstrated quantum communications on optical fibers over 600 km for the first time. To give you more details, here are other details of the company’s latest achievement.
Quantum Internet Could Arrive
Toshiba explained that its upcoming quantum internet would be a global network of quantum computers connected by long-distance quantum communication links. Several large government initiatives to build a quantum internet have been announced, for example in the US, EU, and China.
However, Toshiba said there is currently a key problem. This issue is currently transmitting quantum bits over long optical fibers. Small changes in the ambient conditions, such as temperature fluctuations, cause the fibers to expand and contract. This scrambles the qubits that are encoded as a phase delay of a weak optical pulse in the fiber.
On the other hand, the tech giant manufacturer’s researchers in the UK developed a dual-band stabilization technique to overcome this issue. This sends two optical reference signals, at different wavelengths, for minimizing the phase fluctuations on long fibers.
The manufacturer also found it is possible to hold the optical phase of a quantum signal constant to within a fraction of a wavelength, with a precision of 10s of nanometers, even after propagation through hundreds of kilometers of fiber. Without canceling these fluctuations in real-time, the fiber would expand and contract with temperature changes, scrambling the quantum information.
Aside from this, the giant manufacturer also claimed that the first application for dual-band stabilization will be for long-distance Quantum Key Distribution (QKD), where the company has set up a commercial business with manufacturing in Cambridge.
As of the moment, the manufacturer still hasn’t confirmed further updates about its upcoming quantum internet. Since this connection technology would be quite advanced compared to the current WiFi services, experts and other researchers said that it would still take years before it could be completed.
Right now, all you need to do is sit, relax, and enjoy the current 5G and the upcoming 6G connections. Once the new quantum internet service arrives, you should expect a more expensive price tag for it.
