Quantum Computing

Quantum computing uses the principles of superposition, entanglement and tunneling to address computational challenges that exceed the limits of classical systems. In the recent past, the field has made progress in increasing qubit count, reducing errors, improving early-stage fault-tolerant designs and expanding access through cloud-based systems. These developments are opening new possibilities in optimization, chemistry simulation, cryptography and machine learning. As both hardware and software improve, more organizations are experimenting with combining quantum and classical computing to achieve useful early results. This theme includes companies directly or indirectly involved in building quantum processors, control electronics, cryogenic infrastructure, compilers, error-correction frameworks and application-specific algorithms. The companies featured in this theme support a rapidly growing network of researchers, developers and enterprises seeking early quantum advantage, helping drive steady demand as quantum technologies transition from experimental research stages to commercially scalable solutions.
