Electric field link modularity
With a single wafer holding just a few thousand qubits at most, modularity is critical to scale to millions of qubits. One proposed method uses photonic interconnects, with optical fibres connecting different quantum computing modules. The connection speeds of this extremely complicated technology after years of intense research are low and no simple engineering solution is yet available. This, therefore, provides a potentially unsurmountable bottleneck when scaling up.
We take a completely different approach to modularity, using electric field links between adjacent quantum computing modules. As well as using much simpler engineering, our UQ Connect links between modules are orders of magnitude better than alternative techniques.
UQ Connect has achieved a world record connection rate (2424/s) and connection fidelity (>99.999993%) between two trapped ion quantum computer modules.
