Are quantum majors Google, IBM, Intel and Alibaba backing the right technologies for the long term? Quantum majors Google, IBM, Intel and Alibaba, together with startup Rigetti have so far focussed on building quantum devices based on superconducting qubits. Many expect that quantum supremacy will soon be demonstrated based on such a device. But how…
Excitement mounts as we approach a demonstration of quantum supremacy. However a very long road remains to build a fault tolerant quantum computer Quantum hardware announcements continue to come at speed: Google has just announced Bristlecone, a 72 superconducting qubit device (though it remains to be seen if it can maintain the high fidelity performance of its…
On the 24 Oct 2017 the US Congress held a 3 hour hearing on American Leadership in Quantum Technology, These are the highlights. The discussion is a really great presentation of the remarkable things we can expect from the second quantum revolution.…
