Method For Compressing A Quantum State Vector And Process For Storing A Quantum State Vector
A method for compressing a quantum state vector includes: aggregating a group of several neighboring states of the vector into a cluster of states of the vector, a parameter representative of the probability of this cluster being associated with it and corresponding to the sum of the probabilities of the aggregated neighboring states in this cluster, the probability of each aggregated neighboring state being below a given aggregation threshold, and/or the sum of the probabilities of the aggregated neighboring states in a cluster being below another given aggregation threshold; and preserving a state of the vector not aggregated in a cluster, the parameter representative of its probability remaining unchanged. The method includes several steps of aggregating several distinct groups of several neighboring states of the vector, respectively into several clusters of states of the vector, and/or an aggregation step and a preservation step.

- 1. A method for compressing a quantum state vector, comprising:
at least one step of aggregating a group of several neighboring states of the vector into a cluster of states of the vector,
a parameter representative of the probability of this cluster being associated with it and corresponding to the sum of the probabilities of the aggregated neighboring states in this cluster,
the probability of each aggregated neighboring state being below a given aggregation threshold, and/or the sum of the probabilities of the aggregated neighboring states in a cluster being below another given aggregation threshold,
at least one preservation step,
a state of the vector not aggregated in a cluster being preserved, the parameter representative of its probability remaining unchanged,
the compression method comprising:
at least several steps of aggregating several distinct groups of several neighboring states of the vector, respectively into several clusters of states of the vector,
and/or at least one aggregation step and at least one preservation step.
