Researchers from the University of South Wales Sydney have made a huge advancement in architecture design of quantum computing because they found a way to replace wires in qubits, which represent how information is encoded in quantum computing.
According to Digital Trends, they are using a form of a magnetic field as a replacement. The researches come from the University of South Wales Sydney:
“Pla’s team came up with the idea to generate a magnetic field above the chip instead of using wires,” according to the report. “With this roadblock overcome, the next step is to use this development to create simpler silicon quantum processors. The researchers say this will make it easier to produce devices with more qubits in the future.”
Quantum Inspire has a good analysis of what qubits consist of and how they work. The just of it is that they represent the information encoded for quantum computing. Quantum computing as a whole is still an abstract idea of sorts that has been around for decades. It is the idea of using quantum mechanics for computational purposes. The theory behind it is that it will allow for information to exist in more than one state of 1s and 0s or bits as even supercomputers of today are limited by.
Apple’s A14 Bionic chip, for instance, was mentioned as a move in the direction of quantum computing due to its small size and advancements in SOC design. It shows how Apple and other big giants in tech continue to make advancements toward this idea of computing. It is a nano SOC (5nm in size) that touches on the idea of tunneling.
According to The Quantum Daily, “Between 7–5nm, the laws of physics start to deteriorate and are overtaken by quantum laws, those of the very small… Quantum effects happen in the device as soon as certain device dimensions become very small, due to scaling and its associated requirements.”
Here is how this related to tunneling according to The Quantum Daily’s report:
“So, as chips and the transistors on them become smaller, the problem will become bigger. Tunnelling, for instance, is one of the quantum effects that kick in at these nano-sizes. By definition, tunnelling is a mechanical phenomenon where a wave-function can propagate through a potential barrier. It was only a few years ago many experts in digital electronics, nanoelectronics, semiconductor and the digital technologies sectors thought chips of these minute sizes were impossible to produce.”
Quantum computing will continue to make headways and technologies from big-tech giants like Apple or Google will continue to drive ever closer to seeing it as a reality. it is still just a concept but one day it will most likely change everything we think computing stands for.
Wevolver has a good analysis available for those interested to see just what the potential of quantum computing really is or what problems it can solve if implemented in the future. It goes into the idea of what quantum computing truly is and very abstract theories like the idea of a superposition or a quantum theory going beyond just on or off states in transistors. The future should definitely be bright for what just can be done with the power of technology.
