Instanz: TeilenTeilen:When quantum computers freeze: How even minor, yet frequent, disruptions can cause quantum computing to failSimon Schmitt Kommunikation und MedienHelmholtz-Zentrum Dresden-Rossendorf24.07.2026 09:45The promise of quantum computing is to solve complex problems faster and more energy-efficiently than today’s supercomputers – from optimizing logistics to simulating molecules.
“The quantum Zeno effect is a previously overlooked obstacle to a certain class of quantum computers,” says Dr. Gernot Schaller, head of Quantum Technologies at HZDR’s Institute of Theoretical Physics.
These so-called adiabatic quantum computers operate according to a special principle: Their qubits are always in their ground state, the lowest energy state.
The quantum Zeno effect works in a similar way: Every disturbance disrupts the natural evolution of the quantum state.
However, quantum computer developers can take action to mitigate the quantum Zeno effect, for instance by shielding against electromagnetic radiation and heat.
