Description: The research developed a new decisional monogamy theorem for coset states, establishing a fundamental security tool for quantum cryptography. This theorem allows researchers to prove security guarantees for copy-protection schemes and obfuscation methods like Unclonable Puncture Obfuscation (UPO) by linking entanglement properties to cryptographic hardness.
