SpaceX successfully launches 60 more Starlink satellites.

Starlink is a satellite internet constellation being constructed by SpaceX providing satellite Internet access. The constellation will consist of thousands of mass-produced small satellites in low Earth orbit (LEO), working in combination with ground transceivers. SpaceX also plans to sell some of the satellites for military, scientific, or exploratory purposes. The SpaceX satellite development facility in Redmond, Washington houses the Starlink research, development, manufacturing, and on-orbit control operations. The total cost of the decade-long project to design, build, and deploy the constellation was estimated by SpaceX in May 2018 to be about US$10 billion. SpaceX on Sunday launched another batch of 60 of its internet-beaming Starlink satellites, growing its constellation even further. That makes 835 Starlink satellites launched thus far, though not all of those are operational (some were test satellites that were intentionally decommissioned). The launch, from Florida’s Kennedy

How Do Quantum Computers Work?

WHAT IS QUANTUM COMPUTING? This branch of computer science is based on the principles of the superposition of matter and quantum entanglement and uses a different computation method from the traditional one. In theory, it would be able to store many more states per unit of information and operate with much more efficient algorithms at the numerical level, such as Shor's or quantum annealing. This new generation of supercomputers uses knowledge of quantum mechanics — the area of physics that studies atomic and subatomic particles — to overcome the limitations of classic computing. Although in practice, quantum computing faces evident problems regarding scalability and incoherence, it makes it possible to perform multiple simultaneous operations and eliminates the tunnel effect that limits current nanometric scale programming. Quantum computers perform calculations based on the probability of an object's state before it is measured - instead of just 1s or 0s - which means they ha
