When we whale watch, we need to also be looking for entangled whales. This applies globally.
This poor whale, born into the world and now entangled.

@informaq.bsky.socialHolographic dual discovered for relative entropy of entanglement using minimal tripartition surfaces in random tensor networks. Rigorous proof for 1-3 tensor systems reveals geometric interpretation with nontrivial tri-junction structures.
@informaq.bsky.socialNew noise model reveals when high-dimensional time-bin entanglement outperforms qubits for quantum key distribution. Comprehensive analysis balances temporal resolution with information capacity for optimal secure communication.
@informaq.bsky.socialProves that Gaussian states dominating nonzero separable operators must themselves be separable, settling the conjecture that full inseparability and genuine multipartite entanglement coincide for finite-mode quantum systems.

@jaceblog.bsky.socialWHY TELEPORTATION CANNOT BREAK LIGHT
Entanglement is nonlocal, but communication is not. Aliceâs Bell result is random; Bob needs the classical message to correct it.
No signaling keeps teleportation inside the speed of light.
