On November 13, 2025, Microsoft announced the expansion of its quantum computing facility in Lyngby, Denmark, now its largest quantum site globally. This investment, exceeding DKK 1 billion, will accelerate the development of topological qubits and the Majorana 1 chip, supporting scalable, error-resistant quantum computing and strengthening Denmark's role as a European quantum hub[2]. Despite this significant announcement, Microsoft's stock price declined to $503.92 (-1.41%) during live trading, in line with a broader tech sell-off as the NASDAQ fell 2.28%. There is no evidence that the quantum lab news directly impacted the share price, which appears to be moving with overall market sentiment.
