Researchers Successfully Build Chip-compatible Quantum Memory

Published By : 05 Sep 2017 | Published By : QYRESEARCH

In the recent past, glaring advancements have been made in the field of quantum computing, with the first quantum memory devices already here. However, these devices have always been way too large to be customized into a chip, a basic necessity for them to be useful for practical applications. Now, scientists at the California Institute of Technology (Caltech, USA), in association with those at the University of Verona in Italy, have successfully constructed a quantum memory device that is thousand times smaller, and ideal to be installed on a chip.

Cyber Security and Automatic Learning Possible Applications

This device with optical quantum memory has an area of merely 10 by 0.7 micrometers and takes a photon and encodes it with data. Structure-wise, the device is like a Toblerone candy bar with each ends punctuated with mirrors and an interior of rare earths neodymium. Some of the prospect application of these quantum memory chips can be optimization of processes, cyber security, and automatic learning.

While the bits of a computer data includes only zeros and ones, same bit in quantum memory can have a zero or a one simultaneously, which in turn aids to its coding. This quantum memory device is first of its kind that can be installed on a chip and integrated with nano-size instruments to identify and send signals in quantum bits. These developments have not only raised the chances of commercial application of quantum memory, but also promises to fetch data on demand. Next, the team of researchers is aiming for quantum communications, which will enable the relay of quantum information for longer distances.
