to report single crunch, Christa Asor He stated that Microsoft has been thinking about its roadmap for building a quantum supercomputer for decades until the final result. The Redmonds first demonstrated last year that they are capable of creating Majorana-based qubits. Although these qubits are very stable (especially compared to traditional techniques), they are very difficult and complicated to make.
Microsoft invested in the technology early on, and a year after announcing the first milestone, the team is publishing a new peer-reviewed paper (under review by the American Physical Society Physical Review B) showing that the Redmonds have achieved the first. .
To get to this point, Microsoft showed results from a variety of devices and a lot more data than a year ago. According to Essor, quantum machines are currently very noisy by comparison. These machines are based on physical qubits and are not yet reliable enough to do useful work for scientific or industrial applications.
He said: The next level that we have to achieve as an industry is the level of flexibility. Not only do we have to work with physical qubits, but we also have to put an error-correcting code next to them to allow them to be used as a logical qubit.
Christa Asor It is believed that reaching such a point would require a quantum computer capable of successfully performing a million reliable quantum operations per second with a failure rate of one per trillion operations.
Building hardware-protected qubits is the next step, and Essor said the Microsoft team has made great strides in building such qubits. These qubits will be small (less than 10 microns in each dimension) and fast enough to perform a single qubit operation in less than a microsecond.
After this step, the Redmonds are going to work on entwining these qubits with a process called braiding (a theoretical concept from the early 2000s). With these things in mind, it will be possible to build a smaller multi-qubit system and a complete quantum system can be unveiled.
Microsoft has ambitious ideas and we have to wait and see how successful the Redmonds will be in implementing their ideas. Although IonQ and IBM have achieved similar results with today’s methods for making qubits, Microsoft wants to move beyond the NISQ era.
