Application: Systems and methods for coordinating decisions (Patent ID: US20230274231A1)
Alibaba has filed a patent for systems and methods that use quantum physics to coordinate decisions between non-communicating parties. The procedure involves identifying and expressing the features of a coordinating decisions between non-communicating parties (CDNP) problem in a precise and mathematical manner, finding a solution using quantum states and measurements, and physically implementing the solution. Quantum solutions to CDNP problems have advantages over non-quantum solutions because quantum mechanics can violate Bell inequalities.
The patent claims describe a system for coordinating decisions that includes at least one processor and a computer-readable medium containing instructions. These instructions cause the system to generate a quantum protocol that specifies various elements such as a joint quantum state, observations, measurement operators, measurement outcomes, actions, and mappings. The quantum protocol is based on expected utilities of performing actions given observations. The system provides the quantum protocol to a first subsystem and a second subsystem. The first subsystem obtains an observation, selects measurement operators, performs a measurement on a quantum system, selects an action, and executes the action. The second subsystem performs similar operations on a different quantum system that is entangled with the first quantum system.
The patent also includes claims related to the type of quantum source used, such as static sources like trapped ions, nitrogen-vacancy centers, nuclear spins, quantum circuits, and microwave cavities, or dynamic sources that continuously provide quantum systems. The claims also cover obtaining a utility function that maps observations and actions to utilities, and a probability distribution over observations to determine expected utilities. The probability distribution can be generated using historical data. Additionally, the claims describe the use of embezzling entangled states and different sets of measurement operators for the first and second subsystems. The quantum systems can involve entangled photons, and the measurements can be photon polarization measurements. The detectors used in the measurements can include Pockels cells.
In summary, Alibaba's patent application describes a system and method for coordinating decisions between non-communicating parties using quantum physics. The system generates a quantum protocol based on expected utilities and provides it to subsystems that perform measurements and actions on entangled quantum systems. The patent claims cover various aspects of the system, including the type of quantum source, utility function, probability distribution, and measurement operators.
