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...
