Scientists have achieved a breakthrough in quantum computing by building the smallest machine in the world that can perform calculations at room temperature. The device, which fits on a desktop, uses a single photon as its qubit and does not require complex cooling equipment. This innovation could lead to more efficient and cost-effective quantum computers.
