1Productivity
If classical computing methods are used to solve convex optimization problems with quadratic forms, then solution accuracy can be maintained, but computational time and memory requirements increase exponentially with the number of variables
Solution Approach 1:
The patent replaces classical mechanical computing systems with a quantum computing system that utilizes quantum mechanical principles. Quantum bits (qubits) are used instead of classical bits, allowing the system to represent and manipulate optimization problems in a quantum state space that scales more efficiently with problem size, thereby reducing both computational time and memory requirements.
Solution Approach 2:
The patent changes the fundamental parameters of the computing system by transitioning from classical binary states to quantum superposition states. By representing optimization variables as quantum states and using quantum amplitude encoding, the system can store and process information about all possible solutions simultaneously, changing the scaling behavior from exponential to polynomial in the number of variables.
2Adaptability or versatility
If the number of variables in the optimization problem is increased, then the problem complexity and solution value improve, but the time required to determine a feasible solution increases exponentially
Solution Approach 1:
The patent transitions from classical computational dimensions to quantum computational dimensions by utilizing quantum superposition and entanglement. This allows the system to explore the solution space of optimization problems with many variables simultaneously, effectively adding a dimensional advantage that polynomially scales with problem size rather than exponentially.
Solution Approach 2:
The patent uses quantum state copying and amplitude amplification techniques to efficiently explore multiple solution paths simultaneously. By creating superposition states that represent multiple variable configurations and using quantum amplitude amplification, the system can identify feasible solutions faster than classical methods that must evaluate each configuration sequentially or in limited parallel groups.
