Repost - Perfectly secure quantum communication

A message encoded using a one-time pad cannot be broken. Sending a one-time pad code with perfect privacy has been achieved. A one-time pad message can be sent securely using quantum mechanics and now also send the original message can be sent securely.
Physicists could check quantum states to see if a one time pad message had been overheard. The leakage is detected after it has occurred. An eavesdropper would already have the information by the time physicists found out.
For a one-time pad, a set of random numbers that can be used to encrypt a message. If the one-time pad is overheard, physicists simply disregard it and send another, until they can be sure that the process was completely private.
Getting rid of one-time pads would make sending secure messages far simpler.
The new method uses some initial photons to check for eavesdropping if there is none then the message is sent.
The transmission rate close to security key rates of current commercial quantum key distribution systems.
Quantum secure direct communication (QSDC) is an important quantum communication branch, which realizes the secure information transmission directly without encryption and decryption processes. Recently, two table-top experiments have demonstrated the principle of QSDC. Here, we report the first long-distance QSDC experiment, including the security test, information encoding, fiber transmission and decoding. After the fiber transmission of 0.5 km, quantum state fidelities of the two polarization entangled Bell states are 91% and 88%, respectively, which are used for information coding. We theoretically analyze the performance of the QSDC system based on current optical communication technologies, showing that QSDC over fiber links of several tens kilometers could be expected. It demonstrates the potential of long-distance QSDC and supports its future applications on quantum communication networks.

Playing with a dowel that fell on the floor lol. He just wandered in after lunch and stayed there. Hung out with us for like 3 hours. Was a very interesting day.
His little people hands!!!

In case you didn’t get the memo, concrete is making it big in the design circuit… and it’s being highlighted in the most unusual places. Take for example the Masonic Watch by Aggregate, with its one of a kind concrete body. The Enso does the same thing too. The turntable itself is a rather retro/hipster product and using concrete only makes it more kitschy and cool. With its imperfections, concrete gives a different flavor to a product that has otherwise only seen the use of plastic, glass, metal, and wood. Concrete brings to the product a much needed sense of diversity and a breath of fresh air.
Designed with a simple rounded form that highlights the vinyl disc platter and arm, the Enso comes with a rather integrated form and the only thing breaking it is the walnut wood control panel which juts out to end the monotony and play with one’s visual expectation of continuity. Keeping in sync with the theme of concrete, the wooden panel has two concrete knobs too. What I probably like the most is that the designers try to make it very obvious that concrete doesn’t mean grungy and old-fashioned. The presence of a light strip running around the side of the Enso gives it a futuristic touch, making the turntable look unique and modern both. Plus with vinyl turntables being a massive part of the underground warehouse music culture, concrete may just be the most perfect material selection for its design, I’d say!
Designers: Mikołaj Nicer, Grzegorz Szczupał and Jakub Maciejczyk
