WHAT IS QUANTUM COMPUTING?
Quantum computing is an analog to the computing we know and love. But while computing leverages the classical transistor, quantum computing takes advantage of the world of the infinitely small — the quantum world — to run calculations on specialized hardware known as Quantum Processing Units (QPU). Qubits are the quantum equivalent of transistors. And while the latter’s development is increasingly constrained by quantum effects and difficulties in further miniaturization, quantum computing already thrives in this world.
Quantum refers to the smallest indivisible unit of any physical particle. This means quantum computing’s unit, the qubit, is usually made from single atoms or even from subatomic particles such as electrons and photons. But while transistors can only ever represent two states (either 1 or 0, which gave way to the binary world within our tech), qubits can represent all possible states: 0, 1, and all variations within the combination of both states at the same time.
What is Elon Musk’s Starlink?
Starlink is a satellite constellation system that aims to deliver global internet coverage. This system is ideally suited for rural and geographically isolated areas where internet connectivity is unreliable or nonexistent.
A SpaceX initiative to create a global broadband network, Starlink uses a constellation of low Earth orbit (LEO) satellites to provide high-speed internet services. SpaceX is a privately held rocket and spacecraft company that Elon Musk founded in 2002.

Lumen cuts service to Russia, increasing its isolation – The Washington Post
Lumen, a leading American Internet provider to Russia, announced Tuesday that it was severing business relations in the country, a move likely to increase Russia’s isolation as its citizens slip behind what some analysts are calling a new digital Iron Curtain.
