According to Odaily, Microsoft has introduced Majorana 1, a groundbreaking quantum chip powered by a unique state of matter known as topological superconductivity. This advancement, published in the scientific journal Nature, utilizes a custom material called a top conductor to create and control Majorana particles, potentially expanding quantum computing capabilities to tackle previously unsolvable problems.
Topoconductors are semiconductors that can also function as superconductors, conducting electricity with minimal energy loss at extremely low temperatures. The production of this material requires atomic-level precision and temperatures as low as minus 400 degrees. Despite the complexity and cost, Microsoft emphasizes the benefits of this effort.
Krysta Svore, a Microsoft technical researcher, stated in a company video that this material allows for the construction of a new infrastructure for quantum computing, known as the topological core. This infrastructure could enable the expansion of quantum bits on a chip to millions, rather than just dozens or hundreds.
The project is one of Microsoft's longest-running initiatives, beginning in the early 21st century when Bill Gates was CEO. Under the Majorana architecture, a quantum computer built with controllable quantum bits could solve problems beyond the reach of today's most powerful supercomputers. The current version of the chip contains eight topological quantum bits, but Microsoft claims the architecture can scale to one million quantum bits on a single palm-sized chip, pushing the boundaries of current quantum computing limitations. Microsoft plans to continue refining this technology through research collaborations before commercializing it.
