“It’s really teleportation, like in sci-fi movies.” Scientists have presented the “relay” of teleportation, necessary for the quantum Internet
Scientists “teleported” quantum information between two network nodes that are not directly connected, which is an important step towards the quantum Internet.
A team led by Ronald Hanson from the University of Delft connected diamond-based qubits into a network and then shared the quantum state of one qubit with another node, which was only connected through an intermediate node. This is a key step towards creating a “quantum Internet” in which quantum states can be exchanged without data loss between remote systems.
The quantum network consisted of three nodes, called Alice, Bob, and Charlie, or A, B, and C. Each of them used the spin of the carbon nucleus as a “memory qubit” and the spin of an electron as a “coupling qubit.” Neighboring nodes had quantum states of their communication qubits entangled, so that one directly depended on the other.
To prepare the teleporter, we use a Bob-mediated entanglement exchange protocol similar to the quantum repeater protocol to establish entanglement between Alice and Charlie. Once a successful teleport preparation is reported, the input qubit state is prepared on Charlie and finally teleported to Alice.
Ronald Hanson
When two particles are entangled, the state of one depends on the other, even when they are separated (Einstein called this “spooky action at a distance”). This has been proposed as a way to communicate between qubits. A quantum repeater must operate carefully, so information is passed through entanglement but not revealed when measured, which would destroy the “coherence” that allows a qubit to operate on multiple values at the same time, giving quantum systems their enormous potential power.
This is really teleportation, like in science fiction films. State or information does indeed disappear from one side and appear from the other, and since it does not travel in space between them, [данные] also cannot be lost.

NASA’s Ingenuity helicopter sets a record for speed on Mars

NASA’s Ingenuity helicopter made its sixtieth flight to Mars, during which it set a speed record. It was 28.8 km/h. Before this, the maximum speed at which Ingenuity moved was 24 km/h.
On its sixtieth flight, Ingenuity flew 340 meters at an altitude of 16 meters. Flight time was 133 seconds. It was the fastest helicopter flight on the surface of Mars.
As part of the previous flight, Ingenuity also set a record, but not for speed, but for altitude: it rose 20 meters above the surface of the Red Planet.

This will be the Xiaomi 14 Pro. The first images of the smartphone have been published
For the first time, images of Xiaomi 14 Pro have been published on the Internet – the device is posed “wrapped” in cases, from which it becomes clear that the pictures were leaked by the accessory manufacturer.
Xiaomi 14 Pro demonstrates the evolution of the design of the current Xiaomi 13 Pro: the camera protrusion is almost the same, there are also three modules (the fourth is depicted as a camera module, but it will house a flash.
Xiaomi 14 Pro will receive SoC Snapdragon 8 Gen 3 and a titanium frame. It is also credited with an AMOLED screen with a diagonal of 6.7 inches and a resolution of 3200 x 1440 pixels, a 5000 mAh battery with 120 W charging.
There is scattered data about the camera: some sources say that the device will have a 200-megapixel sensor as the main one, others attribute to it the same inch Sony IMX989 sensor as the Xiaomi 13 Pro. At the same time, everyone agrees that the remaining two sensors will be 50-megapixel.

Alternative browser Vivaldi “takes a bite from the apple”: version for iPhone and iPad presented

The team of the increasingly popular Vivaldi browser announced the release of a stable version for the Apple mobile platform. The beta version of Vivaldi for iOS has been tested for several months.
As the developers promise, Vivaldi for iOS has its own unique look thanks to a set of built-in tools, including tabs, Express Panel, control panels, notes, reading list, and a tracking and ad blocker. The synchronization function between devices is also supported – bookmarks, Express panel, passwords, form data, history of entered addresses and notes are synchronized using end-to-end encryption.
You can store all your important links in the Express Dashboard for quick access. The tab bar is designed to look like tabs on a PC for quick switching. The tab switcher gives you access to public, private, synced, and recently closed tabs.
Built-in Notes let you quickly jot down interesting information. You can copy data from the site through the context menu. Users also have access to a “Reading List” in which they can save web pages for later viewing.
The built-in tracking and ad blocker can be configured for individual sites. To increase privacy, there is a private tabs mode in which search queries, visited sites, cookies and temporary files will not be saved by the browser. Other features include easily changing the search engine, choosing an application icon from a variety of options, an interface for large iPad screens, and so on.
