Engineering Contradiction Analysis
1Reliability
If conventional communication systems are used, then physical communication channels and clear paths are required, but these systems are vulnerable to eavesdropping, jamming, and physical obstacles
Solution Approach 1:
The patent replaces conventional electromagnetic signal transmission through physical channels with quantum entanglement-based communication. By using entangled qubits to transmit information, the system eliminates dependence on physical communication channels and clear lines of sight, thereby removing vulnerabilities to eavesdropping, jamming, and physical obstacles that affect conventional systems
Solution Approach 2:
The patent changes the fundamental parameter of information transmission from electromagnetic signals to quantum states. By encoding information in the entangled states of qubits rather than traditional signals, the system achieves communication that is inherently resistant to interference and cannot be intercepted without collapsing the quantum state, thus improving security and reliability
2Reliability
If physical communication channels are used, then signal transmission is enabled, but signal integrity deteriorates over long distances due to blocking and reduced signal-to-noise ratio
Solution Approach 1:
The patent substitutes traditional signal-based communication with quantum entanglement swapping, which does not rely on physical channels for information transfer. This allows communication to maintain integrity over long distances without the signal degradation, blocking, and noise issues that plague conventional systems
Solution Approach 2:
The patent introduces entangled qubits as intermediaries to transfer information between sending and receiving devices. By using quantum entanglement as the medium of transfer rather than physical signals through channels, the system achieves distance-independent communication that maintains signal integrity regardless of separation distance

AI summary
Systems and methods for digital communication utilizing entangled qubits are disclosed. The disclosed systems and methods exploit selective entanglement swapping to transfer an entangled state between a sending device and a receiving device. Each device includes pairs of qubits that are independently entangled with pairs of qubits in the other device. By selectively entangling the qubits within a pair in the sending device, the qubits of the corresponding pair in the receiving device also are selectively entangled. When the qubits are entangled, they are projected onto a particular entangled state type. Though no information may be transferred through selective entanglement of one qubit pair, systems and methods of the present disclosure determine whether a set of pairs of qubits are entangled by determining whether the distribution of pairs is a correlated or uncorrelated distribution (a probabilistic approach) and transform the distribution type to a classical bit of data.
