INTRO: For the first time, researchers have demonstrated that the properties of the perovskite family of materials can be used to create so-called quantum bits. The findings, published in the journal Nature Communications, pave the way for more affordable materials in future quantum computers.
According to the researchers from Linköping University, Sweden, behind the study, few within the field believed it would be possible. The reason is that the atoms in perovskite materials should, in theory, interact so strongly that the qubit would collapse before the calculation could be completed. However, the experiments conducted by the Linköping team show that it works.
“Our findings open up an entirely new research field,” says Yuttapoom Puttisong, associate professor at Linköping University. The researchers hope that this new research field will eventually contribute to the construction of a functional quantum computer capable of performing advanced calculations that today’s traditional supercomputers cannot manage.
A quantum computer operates using quantum bits, or qubits, to process information. They can be compared to ones and zeros in a traditional computer. What sets them apart is that a qubit does not need to be in one state or the other; instead, it can exist in all states between one and zero. This is known as superposition. As a result, far more information can be handled in a smaller space.
There are many different ways to create a qubit. The most common technique at present is superconducting qubits, used by IBM, Google and others in their attempts to build a quantum computer. However, they are extremely sensitive and operate only at temperatures mere thousandths of a degree above absolute zero. Achieving such cooling requires significant energy and space, making the technology difficult to scale... (MORE - details, no ads)
