Microsoft unveils Majorana 2 quantum chip with 1,000-fold reliability improvement (bbc.com)

• Majorana 2 chip uses topological qubits, 12 qubits on board
• Qubit coherence time improved from milliseconds to 20 seconds
• Target: commercial quantum computer by 2029
• Results not peer-reviewed; skepticism from academia remains

"Microsoft has announced its new Majorana 2 quantum chip, claiming qubits survive an average of 20 seconds versus milliseconds in its predecessor. The company targets a commercially useful quantum computer by 2029. The chip uses topological qubits and contains 12 qubits. Skeptics call for more data, as the accompanying paper is not peer-reviewed."
