Performing qubit manipulation using push notifications is disclosed herein. In one example, a quantum computing device comprises a system memory and a processor device communicatively coupled to the system memory. The processor device is to receive a push notification that includes an identifier of a qubit and a push notification payload, such as a data value to be written to the qubit and/or one or more qubit manipulation commands to be performed using the qubit. Upon receiving the push notification, the processor device obtains write access to the qubit, and then applies the push notification payload to the qubit, for example by writing the data value to the qubit and/or by executing the one or more qubit manipulation commands using the qubit.

Push notification qubit manipulation

An access request to allow a requestor process to access a protected resource is received. A qubit authentication state that identifies a desired state of a qubit is sent to the requestor process. It is determined that the requestor process has caused the qubit to have the qubit authentication state. Based at least in part on determining that the requestor process has caused the qubit to have the qubit authentication state, the requestor process is granted access to the protected resource.

Quantum authentication of protected resources

An access control process executing in a declarative container orchestration system receives a notification that the declarative container orchestration system has received a configuration file that identifies a desired future state that includes a creation of an object. Prior to allowing the declarative container orchestration system to create the object, the configuration file is analyzed. Based on the analysis, it is determined that the configuration file includes a key/value pair that is to be associated with the object. The access control process determines that a user associated with the configuration file lacks authorization to request the key/value pair. In response to determining that the user associated with the configuration file lacks authorization to request the key/value pair, the declarative container orchestration system is prevented from creating the desired future state identified in the configuration file.

Key/value pair metadata authentication for declarative process orchestration environments

A method includes determining characteristics of nodes of a mesh network and selecting one or more nodes of the mesh to receive a payload in view of the characteristics of the plurality of nodes of the mesh network. The method further includes pushing the payload to the one or more selected nodes of the mesh network, wherein the one or more nodes propagate the payload to remaining nodes of the mesh network.

It is determined that a container image comprising a plurality of container image layers generated by a container build engine is to be transmitted from a container image repository to a target computing device. It is determined that a first container image layer of the plurality of container image layers is a sensitive container image layer to be encrypted prior to transmission to the target computing device. A first key generated by a quantum computing system that uses a quantum key distribution protocol, a plurality of qubits and a quantum communication channel to generate the first key is obtained. The first container image layer is encrypted using the first key to generate a first encrypted container image layer. The first encrypted container image layer is transmitted to the target computing device.

An interface in a first unit of software instructions is identified, the interface being configured to be invoked by an invoking unit of software instructions and when invoked, to invoke a function in a second unit of software instructions. A plurality of other units of software instructions are analyzed to identify a set of units of software instructions that are configured to invoke the interface. Based on the set of the units of software instructions and at least one criterion, data descriptive of modifications that modify the first unit of software instructions to remove software instructions that implement the interface is provided.

Identification and removal of redundant interfaces

A query is received from an application. A data store is accessed and a set of data items are extracted from the data store based on the query. Access to the set of data items is provided to the sidecar process. Based on a criterion, the sidecar process causes the set of data items to be modified by at least one of adding additional information to the set of data items, deleting a data item from the set of data items, or altering a data item in the set of data items to generate a modified set of data items. The modified set of data items is provided to the application.

Sidecar data services for enforcing data policies

Biases on quantum bits can be dynamically adjusted based on events. For example, a system can detect an event related to a service executing in a computing environment. The service can rely on a state of a quantum bit of a quantum computing subsystem in performing a computing operation. The system can determine an amount of bias to apply to the quantum bit based on the event. The amount of bias can be configured to modify a result of the computing operation. The system can transmit a control signal configured to cause the quantum computing subsystem to apply the amount of bias to the quantum bit (e.g., while the service is executing).

Dynamically adjusting biases on quantum bits based on detected events

A package delta that identifies differences between a first software package and a second software package is accessed. It is determined that the package delta is to be securely communicated to a second quantum computing system upon the occurrence of a first condition. It is determined that the first condition has occurred. In response to determining that the first condition has occurred, the package delta is transferred to the second quantum computing system using superdense coding.

Superdense coding of software package deltas

Software builds can be constructed based on previously recorded modifications to metadata. For example, a computing device can record modification logs. Each of the modification logs can be associated with a modification to metadata for a software repository. The computing device can also receive, from a client device, a request for the metadata for the software repository at a particular time. The computing device can provide access, for the client device, to one or more modification logs of the modification logs associated with the particular time. The one or more modification logs can be used by the client device to produce a software build having characteristics of the metadata at the particular time.

A quantum process is caused to be initiated on a quantum computing system from a quantum instruction file. A corresponding plurality of temperature values of the quantum computing system associated with an execution of the quantum process is determined at a plurality of different times. Based on the plurality of temperature values of the quantum computing system, a temperature profile that corresponds to the quantum instruction file is generated. The temperature profile is stored.

A quantum computing device determines a plurality of quantum services executing on one or more quantum computing systems. The quantum computing device accesses a dependency map identifying dependency relationships between the plurality of quantum services. The quantum computing device determines computing resource sensitivities for at least some quantum services of the plurality of quantum services. The quantum computing device determines based on the computing resource sensitivities for a quantum service from among the plurality of quantum services that the quantum service exceeds a computing resource sensitivity threshold for the quantum service. The quantum computing device, in response to determining that the quantum service exceeds the computing resource sensitivity threshold, initiates an action based on priority rules.

Blockchain-driven dynamic access control

In one example described herein, a processing device can receive computing metrics from nodes within a mesh network. The processing device can use those computing metrics to derive a maximum message size based on the capabilities of the nodes within the mesh network. The processing device can then transmit the maximum message size to nodes within the mesh network so that the nodes can generate messages that do not exceed the maximum message size.

Managing message sizes in a mesh network

A system can be provided that can determine a first subset of external identity providers associated with permitted access to software applications of an internal computing system. The system can also determine a second subset of external identity providers associated with denied access to the software applications. Additionally, the system can generate a mapping that associates permitted access to the software applications with the first subset of external identity providers and associates denied access to the software applications with the second subset of external identity providers. The system can further receive, from the user device, authentication data. The user device can obtain the authentication data using an external identity provider. The system can detect the external identity provider from the authentication data and, in response to detecting the external identity provider, the system can control access for the user device to the software applications based on the mapping.
