Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If quantum service backup is performed using classical encoding methods, then the backup process is simple and straightforward, but the transmission efficiency and bandwidth utilization are suboptimal
Solution Approach 1:
The patent applies superdense encoding to transform the encoding parameters from classical bits to quantum states, allowing 2 classical bits of service profile information to be encoded into 1 qubit. This parameter transformation achieves higher transmission efficiency while managing complexity through quantum mechanical principles rather than classical computational methods.
Solution Approach 2:
The patent creates a quantum copy of the service profile snapshot using entangled qubits. The source quantum computing device generates entangled qubit pairs, sends one qubit to the target device, and uses measurement and classical communication to transfer the service state information. This copying mechanism enables efficient backup without requiring complete classical serialization of the quantum state.
2Reliability
If quantum service state is captured and transmitted to secondary device, then service restoration capability is improved, but the system complexity and resource requirements increase
Solution Approach 1:
The patent establishes entangled qubit connections between source and target quantum devices in advance, before service failure occurs. This preliminary action creates a pre-configured quantum communication channel that enables rapid service state transfer when needed, improving restoration capability while avoiding the complexity of ad-hoc quantum channel establishment during failure events.
Solution Approach 2:
The patent uses entangled qubits as intermediaries to transfer service profile information between quantum devices. The entangled qubit pair acts as a quantum mediator that correlates the source and target devices, enabling state transfer through measurement and classical communication without requiring direct complex quantum state transmission.
3Quantity of substance
If superdense encoding is used to transmit service profile, then bandwidth utilization is optimized, but the difficulty of implementing quantum communication increases
Solution Approach 1:
The patent segments the service profile information into discrete 2-bit units that can be encoded into individual qubit pairs through superdense encoding. This segmentation allows the complex service state to be broken down into manageable quantum units, each transmitted through entangled qubit pairs, making the implementation more tractable while maintaining optimal bandwidth utilization.

Data Source
AI summary
A quantum failsafe service (QFS) is disclosed herein. In one example, a first quantum computing device executes a QFS that receives a system stress indicator from a system monitor that tracks a status of the first quantum computing device and/or a status of qubits maintained by the first quantum computing device. The QFS determines, based on the system stress indicator, that a quantum service backup is to be performed for a quantum service running on the first quantum computing device, and obtains a profile snapshot representing a current state of the quantum service. The QFS service then performs superdense encoding of the profile snapshot using a first set of qubits entangled with a second set of qubits of a second quantum computing device, and the first set of qubits are sent to the second quantum computing device (e.g., for storage in a classical data repository, according to some examples).
