According to reports Quantum computing is an extraordinary technology that leads to huge leaps in computing speed and efficiency. Although this idea has existed for decades, the implementation of this project is a major engineering challenge.
Researchers at the University of South Wales in Sydney have now announced that they have found a missing piece of the puzzle that enhances the structure of quantum computing chips.
The problem with current quantum computing methods (which use quantum bits or qubits) is that the qubits are controlled by wires that, in addition to taking up space on the chip, also generate heat.
“Until now, controlling the rotation of qubit electrons has relied on creating magnetic fields in microwaves,” said Jarid Pla, the lead researcher. Such magnetic fields are generated by the passage of electricity through a wire along the qubit, but this process can be challenging if done on a scale of several million qubits. Quantum computers require several million qubits of processing to solve huge global problems, such as the design of new vaccines.
The researchers came up with the idea of creating a magnetic field above the chip instead of using wires. To do this, they first removed the wires near the qubits and then developed a new way to create magnetic fields with microwaves. Thus, in principle, control fields for about four million qubits can be invented.
The researchers developed a prototype of the technology and tested it using qubits. Solving this challenge is the next step in using this achievement to make silicon quantum processors easier. Researchers believe that this process will make it easier to produce devices with more qubits in the future.
