Quantum computing investment divide widens as Wall Street bets and banks hesitate

Wall Street is focusing on quantum computing as a next-generation investment theme, but financial institutions differ on when it will be usable. Goldman Sachs tested quantum computing for asset management with Amazon but found no clear results and later cut most of the team. JPMorgan has kept more than 50 researchers and continues long-term work. Interest is also tied to cryptocurrency security, as quantum advances could shorten the time needed to break certain cryptography.
