Quantumcomputing For The Very Curious
"This essay explains how quantum computers work. It’s not a survey essay, or a popularization based on hand-wavy analogies. We’re going to dig down deep so you understand the details of quantum computing. Along the way, we’ll also learn the basic principles of quantum mechanics, since those are required to understand quantum computation.Learning this material … Continue reading Quantumcomputing For The Very Curious

China’s Quantum Communication Network
"The crucial advantage of this so-called quantum key distribution is that if anyone tries to intercept the light particles, they necessarily alter or destroy them. What this means is that any attempt at hacking will immediately be noticed by the original sender and the intended receiver - hence its description as 'unhackable'." A practical application … Continue reading China’s Quantum Communication Network
First Object Teleported from Earth to Orbit
"Back in the 1990s, scientists realized they could use this link to transmit quantum information from one point in the universe to another. The idea is to 'download' all the information associated with one photon in one place and transmit it over an entangled link to another photon in another place. This second photon then … Continue reading First Object Teleported from Earth to Orbit
