The thermodynamics of quantum computing

The thermodynamics of quantum computing

Heat and computers do not mix well. If computers overheat, they do not work well or may even crash. But what about the quantum computers of the future? These high-performance devices are even more sensitive to heat. This is because their basic computational units — quantum bits or “qubits” — are based on highly-sensitive units, some of them individual atoms, and heat can be a crucial interference factor.

Chaos gives the quantum world a temperature

Chaos gives the quantum world a temperature

Two seemingly different areas of physics are related in subtle ways: Quantum theory and thermodynamics. How can the laws of thermodynamics arise from the laws of quantum physics? This question has now been pursued with computer simulations, which showed that chaos plays a crucial role: Only where chaos prevails do the well-known rules of thermodynamics follow from quantum physics.

Long-range QKD without trusted nodes is not possible with current technology

The ARQ19 patent’s claim of achieving long-range quantum key distribution without trusted nodes is unfounded because it relies on an unexplained confidential classical channel between end users that cannot be quantum-based due to distance limitations, making the system’s security ultimately dependent on this non-quantum channel rather than achieving true quantum security.
