JUQ‑565 emerged from a phenotypic screen of ~2 × 10⁶ small molecules designed to suppress Akt phosphorylation in a PIK3CA ‑mutant TNBC line (MDA‑MB‑468). Preliminary hits exhibited a quinazolinone‑pyridine core, prompting a focused SAR campaign that culminated in JUQ‑565 (Figure 1). The molecule combines a 4‑fluorophenyl substituent at the quinazolinone C‑2 position with a 2‑pyridyl‑methyl side chain, conferring high affinity for the ATP‑binding pocket of PI3Kα while minimizing off‑target kinase interactions.

| | Action | Security Goal | |-----------|------------|-------------------| | Preparation | Alice generates a stream of OAM‑encoded photon pairs via spontaneous parametric down‑conversion (SPDC); one photon sent to Bob, the other retained. | Create high‑dimensional entanglement. | | Distribution | Photons travel through low‑loss fiber with mode‑preserving multiplexers; active polarization and OAM compensation modules correct drift. | Preserve entanglement fidelity. | | Basis Choice | Both parties randomly select measurement bases (Fourier‑conjugate OAM sets) using fast electro‑optic modulators. | Enforce complementarity. | | Detection & Sifting | Single‑photon detectors record outcomes; bases are publicly announced, and mismatched events are discarded. | Establish raw key. | | Error Estimation | A random subset (≈5 %) of the raw key is disclosed to compute QBER. | Detect eavesdropping. | | Adaptive Reconciliation | Choose LDPC code based on QBER, exchange syndromes, perform belief‑propagation decoding. | Correct errors while leaking minimal information. | | Privacy Amplification | Apply a universal hash (Toeplitz matrix) to shrink the reconciled key, eliminating Eve’s residual knowledge. | Achieve composable security. | | Authentication | Use FrodoKEM‑derived MAC to authenticate all classical messages. | Guard against active attacks. | | Key Output | The final secret key is stored for one‑time‑pad encryption or as seed material for higher‑layer cryptography. | Provide usable secret. | | Preserve entanglement fidelity
