摘要： A method for generalizing an algorithm configured to synthesize a diagonal product of Pauli rotations to synthesize a product of Pauli rotations comprising X, Y and Z rotations, the method comprising:



Providing a table of p number of rows and m number of columns, where p is a number of qubits and m a number of rotations in the quantum circuit, and where the table comprises X, Y, Z or I entry corresponding to the respective rotations of the qbits;
Determining a pivot row,
and recursively, until all rotations of the product of Pauli rotations are 1-qubit rotations:
Determine a target row,
Conjugate the target row with the pivot row by insertion of predetermined quantum gates on the qubits corresponding to the target row and/or pivot row by calling, at each recursive call, entries of the same type of the pivot row and by always calling first the identity entry.

摘要： A method for detecting malware penetrating a network by identifying anomalous communication between at least two systems of the network, carried out by a computer. For each unique combination of Source IP address and destination IP address, the method includes considering a past period, considering the network flow logs stored during said past period, calculating values of a metric based on data of the network flow logs within the past period and at a given frequency, calculating a baseline which consists in calculating an IQR of all metric values calculated during the past period, determining an outlier threshold from the baseline, considering a current period, calculating a new IQR of all metric values calculated during the current period, and classifying the communication between the two systems of the unique combination as an anomalous communication if the IQR of the current period is greater than the outlier threshold.

摘要： The invention relates to a computer-implemented method for identifying a radar transmitter from a set of corresponding received pulses, each pulse being associated with a respective time of arrival. The method includes determining an observed signature of the radar transmitter based on a distribution of the time gaps between consecutive times of arrival. For each transmitter class among a plurality of predetermined transmitter classes, each transmitter class being associated with at least one expected signature, the method includes calculating a proximity score between the observed signature and each expected signature associated with said transmitter class. Each expected signature is a function of an expected distribution of the time gaps between consecutive times of transmission for said transmitter class, and for a predetermined pulse loss rate. The method also includes assigning the radar transmitter to the transmitter class associated with the expected signature that provides the best proximity score.

摘要： The invention relates to a computer-implemented surveillance method for surveilling an area of interest using a set of drones, the surveillance method including monitoring a number of operational drones among the set of drones. If a change in the number of operational drones is detected, performing a segmentation step for segmenting the area of interest into N sub-areas, N being the current number of operational drones; and performing an affectation step for affecting each operational drone to a respective sub-area for surveilling said sub-area.

摘要： The invention relates to a method for optimizing the execution parameters of a software application on an information processing platform, consisting in iteratively optimizing said parameters at each execution of said application, in which:



for each execution (1) of said application, performance measurements are made (2) and stored (3), in association with the parameters used for said execution;
at the start of each execution of said application, values are determined (4, 6) for a first subset of said parameters by inference (6) from the stored measurements corresponding to a subset of the executions corresponding to a second subset of said parameters.

The system also includes a first digital bus that transfers requested computation tasks from the main processing module to the secondary processing module and transfers results of the requested computation tasks from the secondary processing module to the main processing module. The system also includes a second digital bus that transfers regulation parameters from the main processing module to the voltage regulation module.

摘要： A method for determining at least one machine involved in an anomaly detected in a computing infrastructure comprising a plurality M of machines. This determination is performed by associating with each machine a state vector constructed using metrics and logs. Each vector is also associated with a time window. The monitoring of these vectors makes it possible to detect an anomaly that is then explained via an explanation method that makes it possible to assign an involvement indicator to each machine. The use of this indicator makes it possible to determine the machine most involved.
