Quantum computers promise enormous computational power, but the nature of quantum states makes computation and data inherently "noisy." Rice University computer scientists have developed algorithms ...

There are many algorithms for which it has been mathematically proven that a quantum computer can generate results that would take a classical computer an unreasonable amount of time to generate.

"But an exponential speedup is the most dramatic type of speed up that we expect to see from quantum computers." The key milestone for quantum computing, Lidar says, has always been to demonstrate ...

Quantum is quickly advancing toward commercial utility, bringing revolutionary benefits to numerous industries and solving intractable problems. Quantum computing's potential stems from its very ...
