Previously we talked about creating the first quantum processor consisting solely of interlaced light, now Microsoft has achieved results in this area. Representatives of Microsoft announced that the Microsoft Quantum Lab, located within the walls of the University of Sydney, Australia, has made significant progress in the field of technology for monitoring and controlling qubits, the “building blocks” of quantum computing and communication systems. The technology they developed was already embodied in the form of a CMOS chip, measuring 1 by 2 centimeters, operating at a temperature close to the temperature of absolute zero, 50 thousand qubits of which are controlled with just three conductors.
Note that the technology developed by Sydney researchers is universal, with small changes it can successfully work with any type of quantum hardware used in this area today. This, in turn, means that the developers of quantum computing systems have the opportunity to overcome a number of physical limitations that currently hamper the further development of this direction.
“The chip we developed is one of the most advanced quantum microdevices today”, says Professor David Reilly, Scientific Director of Quantum Lab, “When it was created, not only the qubits themselves, but also the most complex circuits that ensure functioning of these qubits and the chip as a whole”.
The next step, which Microsoft Quantum Lab specialists intend to take, will be to increase the scale of the created devices to a level that gives these devices the opportunity to solve real computing problems. And after that, the new quantum chips will become the basis of the new Azure Quantum cloud service, which is currently under development. This service will allow interested organizations and individuals to completely immerse themselves in the world of quantum computing, starting with online training, creating their own programs in Q# and QDK, and, naturally, launching these applications on the computing power of a quantum cloud.
