Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering. We’re going to tell you a few ways that it has improved your daily life.
The use of quantum physics has made it possible to store data and keep it safe for longer periods of time. For example, it was recently reported in the journal Science that scientists used quantum bits (qubits) to secure their data, allowing them to store up to 1,000 times more data.
It was originally thought that there were some limits to how much information one could store with quantum bits. But a new research report from University of California San Diego physicist Zhongqiang Zhang and his colleagues found that the amount of information you can store with the new type of qubit could potentially be even greater than we previously thought. They were able to store information that is 1,000 times more efficient and 2,000 times more secure than conventional quantum bits.
In addition, the new technology is being applied to many different types of materials. “We can also see that the quantum effects can also be used to store information in silicon, a material that is a lot more sensitive to quantum effects than other materials such as silicon carbide,” says Zhang, who was a graduate student in the UC San Diego faculty of engineering.
These new types of qubits could have a huge impact on quantum information storage, because it is known that the information stored by any quantum system depends on the properties of the quantum system and what it is made of, says Zhang. In addition, he says that the system might even be able to serve as the backbone of quantum computers. “If you are trying to build a quantum computer and you want to have the best performance possible, the qubits are really the best choice,” he says. “Because these qubits can also store the information that is required, if you have one quantum system in the computer, you could have a whole host of qubits.”
Researchers from UC San Diego and Harvard University also published their findings in a study on the quantum behavior of metal nanowires in the latest issue of Nature Nanotechnology. The paper describes the use of silver nanoparticles to manipulate quantum properties of metal nanowires.
