Quantum Walks: Next Frontier in Computational Intelligence

Quantum walks represent a revolutionary quantum computing paradigm that surpasses classical computational methods by leveraging fundamental quantum phenomena like superposition, interference, and entanglement. This technology has been comprehensively analyzed in recent research from China’s National […]

Long-range quantum key exchange with an untrusted satellite.

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.
