Something that a group of scientists from Princeton University would be a breakthrough for the whole future of quantum computing. The team has been successful in demonstrating that two silicon qubits are capable of interacting with each other even when they are placed long-distance. This would make big changes to the future of silicon quantum computers, which are considered revolutionary while thinking of the practical uses. Until now, silicon qubits had to be placed in close proximity for transfer to take place. Published in a journal named Nature, this research means a lot to the scientific community.
While it’s true that silicon qubits are not as popular as the existing ones, almost everyone has acknowledged their potential for the future. Silicon qubits are affordable and can be incorporated in a variety of situations when compared to the existing options. Quantum computers from companies like Google and IBM are still powered by qubits that have been made from superconducting circuitry. Now that the silicon qubits can be set to interact with each other even when placed distantly, this means a lot to the future, where more and more quantum computers are expected.
“The ability to transmit messages across this distance on a silicon chip unlocks new capabilities for our quantum hardware. The eventual goal is to have multiple quantum bits arranged in a two-dimensional grid that can perform even more complex calculations. The study should help in the long term to improve communication of qubits on a chip as well as from one chip to another,” said Jason Petta, the Eugene Higgins Professor of Physics at Princeton and the lead author of the study. It should be noted, however, that time is an important factor when predicting how quickly these technology would be brought into practice.
