he illustrates the point that individual people could be far ahead of corporate giants like IBM and Microsoft in the field of quantum computing - could it be that these companies were duped by an opportunistic researcher into investing in super-cooled machines? did they commit to the wrong projects? Sven Gregori points the finger at intelligence organizations as having their hands on multiple qbit systems. He makes the point that nobody can be quite sure where the leading edge of development is. Let's hope it is in the hands of those that would seek to un-encrypt the banks!
With IBM recently partnering with the university of Japan there is a suggestion that high levels of investment are seeking new platforms to operate/develop on. This would spell bad news for Amazons AWS who has partnered with super-cooled systems in what might turn out to be a large miss-investment by a corporate giant.
