Abstract: Methods, apparatus, and computer program products for quantum communications and quantum information processing are provided. An example method includes determining a received state of a qubit received via a quantum communication link where the received state includes one or more properties of the received qubit. The method further accesses a transmitted state of the qubit where the transmitted state includes one or more properties of the qubit as transmitted. The method continues by comparing the one or more properties of the qubit in the received state with the one or more properties of the qubit in the transmitted state. Finally, the method detects a condition of the quantum communication link based on the comparison between the received state and the transmitted state. In doing so, the embodiments operate to characterize the noise level, security, etc. of a quantum communication interconnect, link, or channel.

Abstract: Devices, methods, and systems are provided. In one example, a method is described to include measuring a cardinality of actual data flows at a flow-processing resource, determining that the cardinality of the actual data flows triggers a congestion control action, and, in response to determining that the cardinality of the actual data flows triggers the congestion control action, implementing the congestion control action with respect to the flow-processing resource.

Abstract: Various embodiments of the present disclosure are directed to accessing a quantum communication channel undetected and/or characterizing this communication channel based upon attempted access. An example method includes accessing a quantum communication channel transmitting one or more qubits. The method includes the introduction of a noise signal to the quantum communication channel and then applying in its absence one or more weak or variable-strength measurements to the quantum communication channel. A strength of at least one measurement of the one or more measurements is based at least in part upon the current noise signal. The method further includes obtaining information associated with the one or more qubits based on the one or more measurements.

Abstract: Bi-directional quantum interconnects are provided that include a first communication module and a second communication module. The first communication module includes a first quantum transmitter and a first quantum receiver, and the second communication module includes a second quantum transmitter and a second quantum receiver. The example interconnect further includes a first communication medium communicably coupling the first communication module and the second communication module such that communication is provided between the first quantum transmitter and the second quantum receiver and between the second quantum transmitter and the first quantum receiver via the first communication medium. The first quantum transmitter and the second quantum transmitter generate qubits having first and second quantum characteristics, respectively, to allow for bi-directional quantum communication over a common channel.
