California Science and Technology developed a quantum memory chip that instantly stores data

According to foreign media reports, researchers at the California Institute of Technology have developed a computer chip capable of storing quantum information in the form of “light” and “nanoscale speed”. This marks the latest breakthrough in quantum computers and networks, enabling faster information processing and data transfer on smaller devices. Memory components in traditional computer systems can only store information in the form of “0” or “1”. Although still in the experimental stage, the basic principle of the quantum computer is the same, that is, “quantum bits” to store data – in addition to “0” and “1”, the qubit also allows two states to coexist. The Calterch Photon Memory Chips Imagine the Caltech-like photon quantum device, which can store and carry information in the form of photons. Because it has no charge or quality, so faster and more secure. “This technology not only minimizes quantum memory devices, but also better controls the interaction between a single photon and an atom,” said Tian Zhong. The chip consists of a memory module, each cell length of 15 microns, width of 0.7 microns, the size and red blood cells. These modules contain “optical cavities” made from crystals of rare earth ions doped, designed for capturing and controlling photons. After cooling the module to 0.5 Kelvin (-727.7 ° C / -458.8 ° F), the research team fired a single photon into each module by means of a heavily filtered laser beam (which was then absorbed by rare earth ions). The photon will be there for 75 nanoseconds and then released again. The researchers then examined the photons to see if they still carry the same information. The research team said the error rate is only 3%. In order to make this chip a realistic choice for long-distance transmission of information in quantum networks, researchers also need to store data for at least 1 millisecond. This is their next main work, in addition to looking for the chip into other circuits in the method. According to Andrei Faraon, author of the paper, the device that can be used to transmit quantum information is an indispensable part of the future development of quantum networks. Details of the study have been published in the recently published journal Science. [Compiled by: New Atlas, Source: Caltech]
