1. Topological quantum computing is here! This thread explains how Microsoft’s Majorana 1 works and what it will mean for a fault tolerant future. I was invited to Azure Quantum Labs and got to hold this amazing new chip! 2. Nature released a paper validating how Microsoft achieved this by creating a new state of matter--a stack of indium arsenide and aluminum built one atom at a time. This is a topoconductor or topological superconductor.
