Scientists have made a big breakthrough regarding quantum computing28 February 2021 ❤ 5
Scientists from the University of Chicago have sent entangled qubit states through a communication cable, this is a massive breakthrough in terms of quantum computing and will hopefully help future scientific projects too, the cable links one quantum network node to another. They have shared in detail what they did, how they did it and why.
They said that by using the same cable scientist have been able to amplify an entangled state to join two qubits in each of two nodes, these joined qubits then entangle with other qubits in the same node. For this specific study at the University of Chicago, scientists used superconducting qubits, which can be manipulated electrically. In addition, they also used a one-meter long superconducting cable. They in total ended up setting up this specific experiment with three superconducting qubits in each of two nodes.
Scientists have also managed to create a system that enables them to make the entire transfer process (this process: node to cable to node) much shorter and much more efficient. Hence it only takes a few tens of a nanosecond, which is extremely quick and which adds to the efficiency. This new faster and more efficient method allowed them to send entangled quantum states with very little lost information.
By using this system many scientists at the University of Chicago were able to amplify and increase the entanglement of qubits at hand, they used one qubit in each node and joined them together by sending a half-photon through the cable. Their overall finished product meant that all six qubits in two nodes were joined in a single globally entangled state.
We hope that in the future these amazing scientists at the University of Chicago will share their findings and experiments, we also hope that due to this experiment quantum computing will become easier and more efficient.
