Quantum Computers Could Freeze Like Ordinary PCs

Researchers at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have identified a possible scaling limit for adiabatic quantum computers.

As qubit counts rise, weak noise and disturbances may act like repeated measurements, preventing the system from reaching its target ground state.

The effect is tied to the quantum Zeno effect, which could make larger machines dramatically slower or even effectively freeze them.

If confirmed, this hidden vulnerability could constrain the size and reliability of practical quantum computers for complex tasks.
