Researchers "teleport" the crucial component of the quantum computer

A team of researchers has brought us closer to a modular quantum computer by "teleporting" one of its essential components.

A world with commercially available quantum computers would be remarkably different from the one we have today, with systems capable of producing data on an unprecedented scale.

However, there is still a long way to go before these systems leave the laboratories of Google, IBM and other institutions.

To hope to change this, a team of researchers from Yale University has successfully demonstrated one of the key steps in building the architecture of modular quantum computers by "teleporting" a quantum grid between two qubits, on demand .

How it works?

Publish your conclusions in NatureThe team explained that the key principle of this realization is through quantum teleportation.

This is a feature of the quantum science of science fiction that has already been shown to send unknown quantum states between two parts without physically sending the state itself.

In the latter case, Yale's team demonstrated a quantum operation – otherwise called a "gate" – without any direct interaction.

These are essential for quantum computing among quantum systems networks, as it is thought that it is able to compensate for the errors found in quantum computer processors.

A first major

With this foundation, the researchers wanted to create a modular quantum computing, where a collection of modules would work separately as small quantum processors in a larger network.

Although this separation is useful for reducing unwanted interactions between each module, it also affects its performance.

By using this new technique of "teleportation", it can however overcome this major challenge.

"Our work is the first time this protocol has been demonstrated where conventional communication occurs in real time, allowing us to implement a" deterministic "operation that performs the desired operation every time," said Kevin. Cabbage from the research team.

Robert Schoelkopf, Chou's research associate, added, "This is an important step in the processing of quantum information using correctable qubits.
