Microsoft Says It Will Have A Useful Quantum Computer In Three Years

Microsoft is doubling down on its quantum computing plans, releasing a new quantum chip called Majorana 2. The company is now targeting 2029 for a useful quantum computer, a year earlier than previously planned. This is due to improved qubits that stay together for an average of 20 seconds, 1,000 times longer than the first-generation chip. Microsoft's topological qubit approach offers hardware-based protection against qubit fragility.
