Quantum computing... and Erlang?

Saw this article on the BBC earlier:

And a few bits just reminded me of Erlang:

Currently, computers solve problems in a simple linear way, one calculation at a time.

In the quantum realm, particles can be in two places at the same time and researchers want to harness this property to develop computers that can do multiple calculations all at the same time.

And…

The team developed a system able to transport information from one chip to another with a reliability of 99.999993% at record speeds. That, say the researchers, shows that in principle chips could be slotted together to make a more powerful quantum computer.

Not quite nine nines, but still :lol:

Sounds like shared state to me :scream:

I don’t think they are actually shared as such, just the same state taking different paths at the same time

Just a message copy then.

Btw, are the rumours true that you are building a Quantum compiler on the BEAM, @rvirding?

As far as I know, IBM holds the record for the number of qubits (1121) and
quantum error-correction looks like needing roughly 100 physical qubits per logical
qubit. So we’re looking at 11 error-corrected virtual qubits as the current record.

Solid work, but I can’t get excited about it. (I mean, if someone was paying me to
work on this stuff I’d be thrilled at how far quantum computing has come, but it has
a long long way to go yet.) I’m pretty sure that Erlang would be a bad fit for a
quantum computer, but it would be fascinating to be proved wrong.
