Two crucial performance metrics for logic gates are their precision and\u003c\/div\u003e\u003cdiv\u003espeed. Quantum processors based on trapped ions have always been the touchstone\u003c\/div\u003e\u003cdiv\u003efor gate precision, but have suffered from slow speed relative to other quantum logic\u003c\/div\u003e\u003cdiv\u003eplatforms such as solid state systems. This thesis shows that it is possible to accelerate\u003c\/div\u003e\u003cdiv\u003ethe logic \"clock speed\" from kHz to MHz speeds, whilst maintaining a precision of\u003c\/div\u003e\u003cdiv\u003e99.8%. This is almost as high as the world record for conventional trapped-ion gates,\u003c\/div\u003e\u003cdiv\u003ebut more than 20 times faster. It also demonstrates entanglement generation in a\u003c\/div\u003e\u003cdiv\u003etime (480ns) shorter than the natural timescale of the ions' motion in the trap, which\u003c\/div\u003e\u003cdiv\u003estarts to probe an interesting new regime of ion trap physics.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eIn separate experiments, some of the first \"mixed-species\" quantum logic gates are\u003c\/div\u003e\u003cdiv\u003eperformed, both between two different elements, and between different isotopes.\u003c\/div\u003e\u003cdiv\u003eThe mixed-isotope gate is used to make the first test of the quantum-mechanical Bell\u003c\/div\u003e\u003cdiv\u003einequality between two different species of isolated atoms.\u003c\/div\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 2021-03-05\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9783030402877\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-3-030-40285-3\u003c\/p\u003e \u003cp\u003eDimensions: 235cm x155cm\u003c\/p\u003e \u003cp\u003ePages: 155\u003c\/p\u003e ","brand":"Springer International Publishing","offers":[{"title":"Default Title","offer_id":47395026600076,"sku":"9783030402877","price":98.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9783030402877.jpg?v=1775770975","url":"https:\/\/fh90cf-fv.myshopify.com\/products\/9783030402877","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
