Microsoft says its new quantum chip is vastly more reliable than its previous version, paving the way for a quantum computer solving commercially useful problems within three years.
Key facts
- Microsoft says the qubits on Majorana 2, its new chip, survive for an average of 20 seconds, rather than the milliseconds of Majorana 1
- If you look at removing forever chemicals, getting rid of microplastics, things like that, those are things traditionally, if we take 15, 20, 30 years to figure out that's a long time," he said
- We will have a quantum machine in 2029 that can solve commercially viable, reasonable problems", said Zulfi Alam, corporate vice president of Microsoft Quantum
- Today, Jason Zander, executive vice president of Microsoft Quantum and Discovery, said: "The team stand behind it 100%
Summary
At the heart of quantum computing are qubits, which offer the promise of answering questions that defeat today's machines, but are notoriously delicate and unstable. Microsoft says the qubits on Majorana 2, its new chip, survive for an average of 20 seconds, rather than the milliseconds of Majorana 1. That means the new chip is 1,000 times more reliable - an improvement in performance the tech giant compares to the difference between a phone that needs charging every day to one which needs charging every few years. "We will have a quantum machine in 2029 that can solve commercially viable, reasonable problems", said Zulfi Alam, corporate vice president of Microsoft Quantum.
