Nobel Laureate Anthony Leggett Passes Away at 87
Anthony J. Leggett died at age 87 in Urbana, Illinois. He was awarded the 2003 Nobel Prize for his theories that explained the superfluid transition of helium‑3, a breakthrough that reshaped low‑temperature physics. His work bridged experimental anomalies and introduced a new quantum state of matter.

Quantum Communication Achieves 85.35% Bit Matching with New Causal Method
Researchers introduced a quantum key distribution protocol that leverages indefinite causal order, a form of causal nonseparability. In ideal conditions the scheme attains an 85.35% bit‑matching probability, corresponding to a 14.65% raw error rate suitable for standard error‑correction codes. The method operates with a low qubit count and without cryogenic cooling, simplifying potential hardware. While still theoretical, the approach promises a new security resource distinct from entanglement‑based QKD.
