Description
There are three key metrics for a remote entanglement link: rate, fidelity, and scalability. All current demonstrations of remote entanglement fail to meet the requirements of large-scale fault-tolerant computing on all three metrics. In contrast, demonstrations of local operations do hit operational requirements. If we assume that at some size a trapped ion quantum computer will outgrow the practical limits of a single module such as shuttling distance or heat load, then remote entanglement links become the limiting factor. I will lay out a plan to overcome this limitation by bringing the rate and fidelity of remote entanglement in line with local operations. In this scheme, integrated optics could parallelize the simultaneous creation of many Bell pairs across various modules. I will touch on initial experimental results on remote entanglement generation using such integrated optics.
