To understand the ambitious roadmaps of quantum hardware players we have to start by understand the contrasting advantages and challenges of each of their technology platforms. As we seek to scale up these solutions, the specific flavour of the technology being employed becomes increasingly important. This overview is taken from a presentation originally delivered at…
Nations and regions around the world are continuing the rapid build-out of publicly funded quantum technology initiatives. Everyone wants to build a future quantum ecosystem in their own back yard. In the commercial space, the bounds of international collaboration are beginning to emerge. Investors need to dress for all seasons. Governments around the world have…
Silicon enjoys an unrivaled lead in human fabrication know-how and investment. Importantly, in its isotopically purified form, it is an ideal neutral material to host sensitive spin qubits. Proponents emphasise the potential of this technology to deliver chip-scale solutions where some other approaches would require ‘building-size’ machines. But spin quibts are delicate. Nanofabricating the right…
