Quantum computing is so last-decade. Get ready to invest in the final frontier… teleportation

social
If 2020 had you wishing you could say “Beam me up, Scotty,” you’re not alone. You may be one tiny step closer to getting your wish… in a few decades or so. Scientists from Fermilab, Caltech, NASA’s Jet Propulsion Laboratory and the University of Calgary achieved “long-distance quantum teleportation” in mid-2020, they confirmed in an academic journal article published last month. It’s another step toward realizing what’s often called quantum computing, and also toward understanding physics on a different level than we do now, perhaps well enough to someday teleport humans. And while there is no ETF specifically for that yet, here are some broad guidelines for thinking about how to invest in very nascent technologies. For starters, it’s good to understand the broad contours of the industry supporting the idea. A...

Opinion: Quantum computers’ power will remake competition in industries from technology to finance

Quantum computers, once fully scaled, could lead to breakthroughs on many fronts — medicine, finance, architecture, logistics. First, it’s important to understand why quantum computers are superior to the conventional ones we’ve been using for years: In conventional electronic devices, memory consists of bits with only one value, either 0 or 1. In quantum computing, a quantum bit (qubit) exhibits both values in varying degrees at the same time. This is called quantum superposition. These ubiquitous states of each qubit are then used in complex calculations, which read like regular bits: 0 and 1. Since qubits can store more information than regular bits, this also means quantum computers are capable of processing greater quantities of information. Having four bits enables 16 possibilities, but only one at a time. Four qubits in...
