GSMem (2015) 1-5.5m/30m with 3G from the RAM bus TEMLEST-LoRa (2025) 87.5m with LoRa over display cables LoPHY (2024) 700m with LoRA MAGNETO (2021) CPU-generated magnetic fields "Rowhammer for qubits" describes hypothetically using electron tunneling and magnetically biased bit flips in standard RAM to simulate quantum operators.
