Variational Quantum Algorithms (VQA)

  Abstract "Applications such as simulating large quantum systems or solving large-scale linear algebra problems are immensely challenging for classical computers due their extremely high computational cost. Quantum computers promise to unlock these applications, although fault-tolerant quantum computers will likely not be available for several years. Currently available quantum device... » read more

Power/Performance Bits: March 23

Metasurface for optical media Researchers at Purdue University proposed a new way to store information in optical media, such as CDs and DVDs, that could improve both storage capacity and read times. The development focuses on encoding information in the angular position of tiny antennas, allowing them to store more data per unit area. "The storage capacity greatly increases because it is o... » read more
