(Phys.org)—Information can never be stored perfectly. Whether on a CD, a hard disk drive, or a piece of papyrus, technological imperfections create noise that limits the preservation of information over time. But even if ...
(PhysOrg.com) -- Although today flash memory is primarily used as a removable storage medium, it's currently becoming more and more appealing for a wider variety of applications. Moving beyond memory cards and flash drives, ...
Many physicists and engineers have been trying to develop highly efficient quantum technologies that can perform similar functions to conventional electronics leveraging quantum mechanical effects. This includes high-dimensional ...
A team of physicists led by Professor Patrick Windpassinger at Johannes Gutenberg University Mainz (JGU) has successfully transported light stored in a quantum memory over a distance of 1.2 millimeters. They have demonstrated ...
