Rising Nuclear Risk as US, Russia, and China race for modernization of all the three legs of their strategic Triad

The strategic triad is formed by  land-based intercontinental ballistic missiles (ICBMs)  stored in silos containing one or many nuclear warheads, nuclear-powered ballistic missile submarines (SSBNs), and land-based long-range strategic bombers  that carry gravity bombs of different kinds, but also long-range cruise missiles. The triad gives the commander in chief the …

IBM roadmap to 1,121-qubit Condor chip by 2023, is the inflection point for lower-noise qubits to deliver Quantum advantage

Unlike digital computer which understands only a bit that can have only one of two values: “1” or “0,”  qubits have special property termed superposition,  which can simultaneously be a 0 and/or a 1. This enables quantum computers to weed through millions of solutions all at once, while desktop PCs …

Amid increasing space warfare threst, Militaries developing troposcatter systems again as a backup to Satellite communication

The dominant mode of communication today uses antennas to transmit information carrying high frequency signals using antennas which at the receive site produce an electrical signal which is amplified and demodulated by the receiver equipment. However this form of communication is limited by line of sight propagation limiting the range …
