Physicists at the University of Oxford have accomplished a landmark achievement in quantum science, demonstrating for the first time a fourth-order quantum effect known as “quadsqueezing”.<\/p>\n

The breakthrough, detailed in Nature Physics on May 1, was achieved using a single trapped ion confined between electrode structures and manipulated with precisely calibrated laser fields.<\/p>\n

Remarkably, the Oxford team generated this elusive quantum interaction more than 100 times faster than would be expected through conventional experimental approaches.<\/p>\n

The research opens significant new avenues for quantum simulation, sensing and computing technologies, marking a proud moment for British physics research.<\/p>\n

Numerous physical systems behave as oscillating objects, much like springs or pendulums, and in quantum mechanics, these are termed quantum harmonic oscillators.<\/p>\n

Controlling such oscillations underpins modern quantum technologies, from ultra-precise measurement instruments to advanced computing systems.<\/p>\n

Standard squeezing techniques redistribute quantum uncertainty, sharpening one property whilst increasing imprecision in another.<\/p>\n

This principle already enhances gravitational-wave detectors such as LIGO.<\/p>\n

However, more sophisticated interactions \u2014 trisqueezing and quadsqueezing \u2014 have long eluded experimentalists.<\/p>\n

These higher-order effects are inherently feeble and diminish rapidly as complexity increases.<\/p>\n

Consequently, the desired quantum behaviour typically becomes overwhelmed by noise before it can be observed, presenting a formidable experimental challenge.<\/p>\n

The Oxford researchers devised an ingenious solution by applying two precisely controlled forces to a single trapped ion simultaneously.<\/p>\n

This technique builds upon theoretical work proposed in 2021 by Dr Raghavendra Srinivas and Robert Tyler Sutherland.<\/p>\n

Each force individually produces a straightforward, linear effect, yet their combination yields something far more powerful through a phenomenon called non-commutativity.<\/p>\n

Dr Oana B\u0103z\u0103van, the study’s lead author, explained: “In the lab, non-commuting interactions are often seen as a nuisance because they introduce unwanted dynamics. Here, we took the opposite approach and used that feature to generate stronger quantum interactions.”<\/p>\n

She added: “The fourth-order quadsqueezing interaction was generated more than 100 times faster than expected using conventional approaches.”<\/p>\n

The technique is already being extended to systems with multiple modes of motion and has been combined with mid-circuit measurements of the ion’s spin to simulate a lattice gauge theory.<\/p>\n

Because the method relies on tools already available across various quantum platforms, it could provide a broadly applicable route to advanced quantum simulation, sensing and computation.<\/p>\n

Dr Raghavendra Srinivas, who supervised the research, expressed considerable enthusiasm for what lies ahead.<\/p>\n

“Fundamentally, we have demonstrated a new type of interaction that lets us explore quantum physics in uncharted territory, and we are genuinely excited for the discoveries to come,” he said.<\/p>\n","protected":false},"excerpt":{"rendered":"Physicists at the University of Oxford have accomplished a landmark achievement in quantum science, demonstrating for the first…\n","protected":false},"author":2,"featured_media":626149,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[49],"tags":[167787,3,199,79,1500],"class_list":["post-626148","post","type-post","status-publish","format-standard","has-post-thumbnail","category-physics","tag-best-of-britain","tag-news","tag-physics","tag-science","tag-sgg"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/626148","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=626148"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/626148\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/626149"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=626148"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=626148"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=626148"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
