Microsoft says it has taken a big step forward in the field of quantum computing by designing a solution to control thousands of qubits in quantum computers.

Microsoft's activities in the technology industry are not limited to the development of the Windows operating system and the production of Surface series devices; He also works in the field of quantum computing and does interesting things with quantum computers.

According to Digital Trends, Microsoft has recently claimed that it has made significant progress in the field of quantum computing. Researchers at Microsoft say they have partnered with researchers at the University of Sydney in Australia to find a way to control thousands of qubits. Qubit is the basic unit of quantum information, which is equivalent to binary bits in classical computers and operates at extremely low temperatures.

Analysts say that quantum computers can greatly change our understanding of computing; For this reason, any progress in this area is very important. Designing a Microsoft solution is very important; Because one of the big problems in designing quantum computers is the issue known as Qubit Decoherence.

Digital Trends expert writes that qubit inconsistency is one of the main causes of errors in quantum computing. Errors related to qubit asymmetry are due to the way the environment interacts with the qubits, which cause the quantum state of the qubits to change.

In an interview with Digital Trends, David Riley, lead researcher and leader of the Microsoft Quantum Sydney Research Project, told Digital Trends that each qubit should be controlled by a single set of wires. These wires usually travel from the electronic racks at room temperature to the qubits at the bottom of the diluent refrigerator at a temperature of 0.01 K, which is very close to absolute zero.

In this method, a maximum of 50 qubits can be controlled; Therefore, if you rely on this particular method, you will never be able to control thousands of qubits. Removing the wires from the electronics rack is largely reminiscent of computers from the 1940s, and this is inconsistent with the way integrated circuit chips work.

Researchers at Microsoft and the University of Sydney in Australia have come up with an innovative way to solve this problem. Microsoft's solution includes a control chip known as a Gooseberry. This chip allows scaling to the control system and eliminates the limitations of the first method. The control chip consumes only a small amount of energy, which means that it does not heat the qubits.

Riley says the sheep chip is the most complex electronic system that can operate at this temperature. This is the first time that a Mixed-Signal Chip chip with 100,000 transistors can operate at a temperature of 0.01 Kelvin (equivalent to -273.05 degrees Celsius).

According to Riley, the strategy designed by Microsoft and researchers at the University of Sydney is a major step forward in the field of quantum technology; However, according to Riley, there are still more steps to be taken to develop truly functional quantum computers.

An article describing a Microsoft-specific solution was recently published in the journal Nature, entitled "Cold-generating interface for controlling large quantities of qubits."
