Clean News piece. 527 words, headline accurate, quoting strategy is clearly disciplined. Includes appropriate What We Don't Know caveats about scaling and operational benchmarks.

{"source-0_oxford":"Verified: Published 1 May 2026, Nature Physics, paper title 'Squeezing, trisqueezing and quadsqueezing in a hybrid oscillator-spin system'. Băzăvan quote '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' verbatim. 'more than the sum of their parts', 'more than 100 times faster than expected using conventional approaches', 'new type of interaction that lets us explore quantum physics in uncharted territory' all verbatim. Sutherland (UTSA) 2021 theory verified.","source-1_physorg":"Snapshot is Archive.org capture (May 2 2026); content matches Oxford release verbatim. Băzăvan and Srinivas quotes verified.","source-2_quantuminsider":"Verified: '100 times faster than conventional approaches', Băzăvan and Srinivas quotes match the article's attributions verbatim.","source-3_sciencedaily":"Verified: 'May 1, 2026' publication date, 'first-ever' framing, Băzăvan quote verbatim.","source-4_eurekalert":"Verified: '1-May-2026' release date, all key quotes verbatim, paper title and 2021 theory citation match."}

All quoted material traced verbatim. Author names (Băzăvan, Srinivas, Sutherland, UTSA), affiliation (Oxford Department of Physics), publication venue (Nature Physics), date (1 May 2026), paper title, 2021 theoretical proposal, and 100x speed-up claim all verified across multiple sources.

APPROVE_WITH_CORRECTIONS. Cryptography, sources, content, and quoting discipline all clean. Only finding is the physics.ox.ac.uk allowlist gap, an editorial-process concern. Publishable as-is.
