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, this space 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.

Here, we have identified five pure-play quantum computing stocks that have not participated in Wall Street’s rally year to date. However, these stocks currently enjoy significant price upside potential in the second half of 2026.

The companies are: D-Wave Quantum Inc.…
