Two crucial performance metrics for logic gates are their precision and.speed. Quantum processors based on trapped ions have always been the touchstone.for gate precision, but have suffered from slow speed relative to other quantum logic.platforms such as solid state systems. This thesis shows that it is possible to accelerate.the logic "clock speed" from kHz to MHz speeds, whilst maintaining a precision of.99.8%. This is almost as high as the world record for conventional trapped-ion gates,.but more than 20 times faster. It also demonstrates entanglement generation in a.time (480ns) shorter than the natural timescale of the ions‘ motion in the trap, which.starts to probe an interesting new regime of ion trap physics..In separate experiments, some of the first "mixed-species" quantum logic gates are.performed, both between two different elements, and between different isotopes..The mixed-isotope gate is used to make the first test of the quantum-mechanical Bell.inequality between two different species of isolated atoms.. | | 出版日期 | Book 2020 | | 關(guān)鍵詞 | Quantum Computing; Trapped Ions; Fast Gates; Mixed Species Gates; Non-Adiabatic Entanglement; Mixed Speci | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-030-40285-3 | | isbn_softcover | 978-3-030-40287-7 | | isbn_ebook | 978-3-030-40285-3Series ISSN 2190-5053 Series E-ISSN 2190-5061 | | issn_series | 2190-5053 | | copyright | Springer Nature Switzerland AG 2020 |
