NOT EVERYONE IS CONVINCED BY MICROSOFT'S TOPOLOGICAL QUBITS

Summary from the TLDR newsletter

Microsoft's quantum team made waves last month by announcing its first topological quantum chip, the Majorana 1. Quantum computers run on qubits valued at 0, 1, or some superposition of the two - topological quantum computing is a fundamentally different approach to building a qubit that would be theoretically less fragile. Proving the claims that it has created at least a single topological qubit remains difficult for the Microsoft team. Despite difficulties, topological quantum continues to be a very promising approach.
