IBM Proves a Quantum Computing Advantage Over Classical
Next Big Future
By Brian Wang

IBM researchers have mathematically validated certain problems that require only a fixed circuit depth when performed on a quantum computer regardless of how the number of quantum bits used for inputs increase; these same problems require larger circuit depths on classical computers. The proof is that there will be problems that can only be executed on quantum systems, and others which can be conducted much faster on quantum computers. The research proves fault-tolerant quantum computers will do some tasks better than classical computers, and offers guidance on how to further current technology to leverage this as rapidly as possible. This marks the first demonstration of unconditional partitioning between quantum and classical algorithms. In practical terms, short-depth circuits are part of the deployments of algorithms, so this result does not specifically state how and where quantum computers might be better options for particular business problems.  ...
