Super cool to see the AEON qubit finally realized Thaddeus Ladd and Jason R. Petta. Beautiful data. Indeed, sometimes we (cc Yun-Pil Shim) must wait a long time, almost 10 years in this case (https://arxiv.org/pdf/1602.00320)! The most interesting aspects of the AEON qubit to me are one, yes, it’s compatibility with single exchange pulse two-qubit gates (which could be a several 10x improvement in resource count) but also it’s ability to maintain it’s sweet spots even when converting between separated exchangle-only and always-on regimes…and then after that it’s unique compatibility with longitudinal readout (https://arxiv.org/abs/1704.05876). So many interesting ideas still out there waiting to be explored with quantum dot qubits.
