Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If quantum entanglement is distributed through intermediaries, then transmission distance and coverage are improved, but trust issues and security risks worsen
Solution Approach 1:
The patent extracts the state information from the quantum entanglement distribution process and meters it separately through classical channels. This separation allows the quantum particles to be distributed through intermediaries for extended distance while the state information is independently controlled and billed, eliminating the trust issue between quantum transmission and billing verification.
Solution Approach 2:
The patent introduces a classical communication channel as an intermediary to transmit state information between the quantum entanglement distribution system and customers. This intermediary enables fair billing by allowing verification of entanglement usage through classical measurement data without compromising the security of the quantum key distribution.
2Area of stationary object
If quantum entanglement particles are distributed freely, then communication coverage is improved, but billing accuracy and fairness worsen
Solution Approach 1:
The patent performs preliminary metering of state information before the quantum entanglement distribution is complete. By measuring and recording the state of quantum particles in advance through classical channels, the system can accurately bill customers for the actual entanglement they receive, regardless of distribution losses or reception rates.
Solution Approach 2:
The patent implements a feedback mechanism where measurement results of quantum particles are transmitted through classical channels to verify entanglement distribution. This feedback loop enables the system to track actual usage and provide accurate billing based on measured entanglement quality and quantity received by customers.
3Ease of operation
If state information is provided to recipients, then ability to interpret measurements is improved, but security and secrecy worsen
Solution Approach 1:
The patent uses classical communication channels as intermediaries to transmit state information between the quantum system and recipients. This intermediary approach allows recipients to obtain necessary measurement interpretation data while the quantum entanglement itself remains secure, as the classical channel can be authenticated and the quantum keys remain undisclosed.
Solution Approach 2:
The patent changes the form of information transmission by separating quantum state information from classical measurement interpretation data. The quantum particles carry the secure information while their classical state parameters are measured and communicated separately, allowing recipients to interpret measurements without directly accessing the quantum state itself.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables fair billing based on actual entanglement usage and ensures secure communication by detecting eavesdropping, maintaining secrecy, and providing trust-less transmission across varied geographic locations.
Implementation Method 1
A metered quantum entanglement distribution system applies unitary transformations to entangled quantum particles, distributing them in a manner that requires recipients to receive state information to interpret measurements
Implementation Method 2
Entanglement is a strong correlation between quantum particles, such that the quantum particles are inextricably linked in unison even if separated by great distances
Implementation Method 3
Superposition allows a quantum system to be in multiple states at the same time. For example, whereas a classical computer is based on bits that are either zero or one, a qubit may be both zero and one at the same time, with different probabilities assigned to zero and one

AI summary
A system and method for providing metered quantum entanglement-as-a-service are described. Entangled pair source nodes apply a unitary transformation to generated entangled quantum particles, such that the entangled quantum particles are transformed into a given one of a plurality of transformed states that are selected randomly or in a manner that is not readily apparent to customers. The transformed entangled quantum particles are distributed to recipients, such as customers. However, in order for the recipients to be able to use the received entangled particles to communicate shared information, such as a shared secret, the recipients require knowledge of the respective states of the entangled quantum particles resulting from the randomly selected transformations. The state information is metered out in response to receiving payment or other authorization indicating a recipient/customer has complied with terms of use of the quantum entanglement distribution service.
