A note to cast further suspicion on the immediate risk severity:
The researchers indicate use of a computer built with superconducting qubits in the abstract, to that, superconducting qubits present barriers such as
- limited coherence time due to common atmospheric muon events, and resulting phonons
- limited topological connectivity, further increasing needed coherence time.
- reikonomusha 4y agoLimited coherence time is not explained as simply as "atmospheric muon events". There are a variety of reasons, some environmental, others a result of imperfect fabrication, etc. that contribute to decoherence, gate error, etc.
- meltyness 4y agoI know that, but I recall specific literature reflecting the specific effect mentioned[0] and it seems intuitive that the surface area and orientation currently in use for these qubits may potentiate the effect, I think the other effects you list are barriers to other qubit registers as well.
