IBM Buys Quantum Dot Qubit Startup After 2 New Research Papers

Summary
IBM acquired a company developing quantum-dot qubits after two new papers outlined different ways to use the technology.
quantum dots trap a single electron in a manufactured structure, and supporters argue they could scale using the same fabrication methods used for conventional processors.
The deal highlights a key divide in quantum computing: some platforms already run into the thousands of qubits, while rivals are still proving a few qubits can scale more effectively.
Separately, another company unveiled a processor holding 100 individual electrons in diamond defects, underscoring how multiple qubit approaches are still competing for a scalable path.
If existing chip factories can mass-produce quantum dots, will the current leaders in superconducting quantum computers suddenly become obsolete?
Could room-temperature diamond defects secretly outpace massive cryogenic supercomputers in the race to build the first truly scalable quantum internet?
