Oxford University researchers are a step closer to a quantum computer

quantum computers

Researchers at Oxford University were recently able to keep a quantum system alive for 39 minutes. In the realm of quantum computing, those 39 minutes are a life time. Quantum bits typically only survive at room temperature for a few seconds.

Building a quantum computer is not a simple task. While 39 minutes may not seem like a long time, in only takes one hundred thousandths of a second to flip nuclear spin of a phosphorus ion.

Stephanie Simmons, from Oxford’s Department of Materials said, “Having such robust, as well as long lived qubits, could prove very helpful for anyone trying to build a quantum computer.”

Oxford’s success is getting a qubit to survive “opens up the possibility of truly long-term coherent information storage at room temperature,” said Mike Thewalt, a researcher working on the project

All of these long lasting qubits share the same quantum state, which is only the beginning. To perform calculations, however, a quantum computer will need to have qubits in different quantum states. Researchers are still a long way from having a fully operational quantum computer but they have taken a huge step closer to that computer being a reality.

    Interesting article, but not really the quality I expected from Dottech. Explain what quantum bits are, a bit of a summary of what a quantum computers are for those who don’t know. Make it clear that the abbreviation is cubits so the quote makes sense. Explain what you are saying, for example, “in only takes one hundred thousandths of a second to flip nuclear spin of a phosphorus ion.”
