Vitaly Ginzburg, the Russian physicist who developed the Soviet H-bomb, has died after a long illness. He was 93.

Ginzburg won the Nobel physics prize for developing the theory behind superconductors – materials which allow electricity to pass without resistance at very low temperatures. Ginzburg wrote that he worked together with fellow Soviet physicist Andrei Sakharov — later a famous dissident — on the Soviet H-bomb project and said they developed the two key ideas which made it possible to create the device.
