Flying quantum bits

The important point of quantum information technology is that, for example, quantum computers, including quantum cryptography, are using quantum bits or “qubits” as basic information units, the industry is not the same as the classic qubits. Able to have a value of only 0 or 1 The superposition called in this respect makes it possible to create many quality computers that use status. superposition These are for calculating efficiently and are faster than classic computers. Conversely, those states are sensitive and cannot be easily transmitted using conventional methods. The problem with that is that the state of the first qubit still needs to be changed to qubit “fly”, such as photons and then return to other qubit stations This way, Wallraff and his co-workers have achieved recognition. For example, passing from a qubit of a superconducting city to another place away.

Physicists have connected two qubit superconductors using the same coaxial industrial cable that is used to connect to the antenna terminals. The quantum state of the first qubit, identified by the number of superconducting electrons (Also known as double cooper) contained in it has been transferred to the microwave photon of the reflector using many precisely controlled microwave frequencies. From the photographer, the photon can fly through the active bull line to the second resonant, which in the microwave wave moves the quantum state to the second qubit. Similar at Yale University

More object oriented probabilistic

“The highlight of our approach is the transmission of the quantum industrial city as an identifier, which shows that it can be operated with just a click of a button,” Philippe Québecis, PhD researcher of Walsaff’s lab In previous experiments, the transfer of quantum status was already known. However, this transmission is a probability: sometimes it works However, in most cases it was not Signaling that achieves goals can be illustrated by signals. Whenever the transmission is not effective Similarly, the quality of the quantum transmission rate is greatly reduced. For practical use deterministic Same as this time showing that ETH is clearly featured.

“Our industrial transmission rates for quantum cities are at the highest level ever, and at 80% loyalty for our transmission is excellent in using the first protocol,” Andreas Wallraff said researchers can use this technique for generating quantum engine failures between qubits up to 50,000 times per second. The data transfer process takes less than one millionth of a second, indicating that there is a gap for the industry to adjust the data transmission rate. Quantum entanglement creates a familiar link between both quantum objects, even at large distances. Features used in encoding or moving quantum data

Quantum transfer for quantum computers

Next, researchers wanted to use two qubits each as a transmitter and then the receiver, which would allow the industry to switch between qubit possible. The process, as mentioned above, is useful for quantum computers. Which should be done in the next few years Until now only a few people But when striving to build a large computer about two to three hundred qubits, it must be worrying that it will connect most effectively to take advantage of the advantages of quantum computers in The best way

As with a single computer group that is currently used, quantum computer modules can be connected using the Wallraff technique. The distance for data transmission, which is now about one meter, may be increased. The suspicion of Wallraff, including his co-workers, showed that the cables are very salty and that superconductors can send photons in the distance. With tens of millions with very little loss The wiring of the quantum computer center is quite unlikely.
