Researchers describe quantum jamming as a hypothetical way to alter entanglement without breaking causality.
Jamming could disrupt device-independent cryptography by weakening entanglement monogamy assumptions.
Physicists view jamming as a tool to refine definitions of causation in quantum theories.
The article traces the idea from Grunhaus, Popescu, and Rohrlich’s early work to modern reexaminations in 2025.
No-signaling remains a central assumption when considering what lies beyond quantum mechanics.
Colbeck and Vilasini seek principles beyond no-signaling to explain jamming effects.
The discussion connects quantum jamming to broader questions about causation and physical theories.
The piece notes that device-independent cryptography hinges on entanglement properties that jamming could affect.
Experts emphasize ongoing dialogue and research to clarify terms and principles around jamming.

A new study links a blood-based biological age marker, MileAge delta, to higher dementia risk in a large UK Biobank cohort.
Higher MileAge delta means the blood profile appears older than expected, correlating with greater dementia risk.
The strongest association was with vascular dementia, especially for those with the APOE gene linked to Alzheimer's.
Genetic risk (APOE) combined with biological aging marks could markedly raise dementia risk, per study authors.
Researchers caution the study is observational and cannot prove causation between aging markers and dementia.
The UK Biobank data included more than 223,000 participants, with analyses based on a single blood measurement.
Experts say metabolomic aging may be modifiable through lifestyle changes to slow aging and dementia risk.
The MileAge measure compares metabolite-predicted age to actual age to estimate biological aging.
Study authors emphasize the need for broader validation before clinical use of MileAge in dementia risk prediction.
The study notes that participants were healthier and mainly of European descent, limiting generalizability.
