Researchers at Microsoft (USA) engineered a new way to represent a logical qubit with hardware stability. They reported that the device could induce a phase of matter characterized by Majorana zero modes, such devices have demonstrated low enough disorder to pass the topological gap protocol, proving the technology is viable. They stated that it has created a new measure to gauge the performance of a quantum supercomputer: reliable quantum operations per second (rope), a figure that describes how many reliable operations a computer can execute in a single second. They suggest that for a machine to qualify as a quantum supercomputer, its rQOPS needs to be at least 1 million. They noted that such machines could reach a billion rQOPS, making them truly useful. According to the researchers this represents a first step toward the creation of not just a quantum computer, but a quantum supercomputer… read more. Open Access TECHNICAL ARTICLEÂ Â
