Abstract: The present disclosure relates to an optical module and a method of operating the optical module. The optical module includes transmission channels and a monitor channel. The transmission channels produce a plurality of optical signals. Each transmission channel includes an equalizer circuit and a first converter. The equalizer circuit adjusts a received electrical signal to produce an adjusted electrical signal, and the first converter converts the adjusted electrical signal into the optical signal produced by the respective transmission channel. The monitor channel includes an optical multiplexer, a second converter, and a processing circuit. The optical multiplexer selects a first optical signal produced by a first transmission channel of the plurality of transmission channels. The second converter converts the first optical signal into a first electrical signal. The processing circuit adjusts a first equalizer circuit of the first transmission channel. Adjusting the first equalizer circuit adjusts the first optical signal.

Abstract: A single-shot graph state generator prepares matter qubits in an entangled graph state. Each matter qubit may be in a first state, a second state, or an excited state. The single-shot graph state generator drives the matter qubits with one or more pulses that cause a transition from the first state to the excited state. A decay of a matter qubit from the excited state to the first state generates a corresponding photonic qubit. The single-shot graph state generator measures the matter qubits to teleport the entangled graph state to the photonic qubits.

Abstract: At a contact center that operates to provide customer service to callers by receiving calls from the callers and directing the callers to desired endpoints that deliver information to the callers based upon an expressed intent of each caller associated with each call, a current call by the contact center is processed utilizing an Interactive Voice Response (IVR) model or a Conversational Menu (CM) model. The IVR model processes the current call by directing the current caller to a selected endpoint via navigation through a specific navigational path of nodes in a hierarchical IVR tree of nodes. The CM model processes the call by analyzing a verbal utterance of the current caller at an initiation of the current call and directing the caller to the selected endpoint so as to bypass nodes within the specific navigational path of nodes of the hierarchical IVR tree of nodes.

Abstract: A method, computer system, and computer program product are provided for securely controlling playback of a recorded collaboration session. A plurality of video feeds is received from a plurality of client devices of users participating in a video meeting, wherein each video feed is encoded by each client device in an encoded format that distorts the video feed, wherein a unique key is used by each client device to encode the video feed. The plurality of video feeds are stored in the encoded format. A request is received to view a stored video feed, wherein the request includes the unique key used to encode the stored video feed. In response to determining that the requesting entity is authorized by a user of the stored video feed to view the stored video feed, the stored video feed is decoded and provided to the requesting entity.

Abstract: Techniques for programming an omnidirectional programmable client interface module (OPCIM) to receive a control signal and for configuring a set of outputs of a first output and a second output. Programming the OPCIM for routing the control signal from one input of the OPCIM to the first output and the second output of the OPCIM to output a first output signal and a second output signal to a first Line Card and a second Line Card coupled to each output, respectively. In response to a failure of at least either one of the Line Cards, automatically enabling reprogramming the OPCIM for routing the control signal to either Line Card that is still operational to prevent a service interruption in sending the control signal from one input to an output of either the first output or the second output to the Line Cards coupled to outputs of the OPCIM.
