Abstract: Methods, apparatuses, and computer program products are provided for detecting an eavesdropper or other network disturbance on a quantum communication network, based on measurements performed on auxiliary degrees of freedom. An example method includes receiving a quantum state with transmitted physical observables imparted to the quantum particle/s on a first set of one or more degrees of freedom. The method further includes determining a received physical characteristic, based on the received observables within each of an auxiliary set of one or more quantum degrees of freedom. The method includes accessing data reflecting the transmitted physical condition on the auxiliary set of one or more quantum degrees of freedom and comparing the received physical characteristic of the quantum state with the transmitted physical condition. Finally, the method includes generating a notification of interference along the quantum interconnect link upon detecting a difference between the received observables and the interconnected observables.

Abstract: An apparatus comprises a support structure and one or more first optical components on the support structure that communicatively couple with a first endpoint. The one or more first optical components are configured to output and receive optical signals that travel over a free space medium to establish a secure link between the first endpoint and a second endpoint.

Abstract: Embodiments are disclosed for providing a dual-facet distributed feedback (DFB) laser in a Mach-Zehnder modulator (MZM) structure. An example system includes an MZM structure that includes a DFB laser, a first waveguide interferometer arm structure, and a second waveguide interferometer arm structure. The DFB laser is configured to generate an optical input signal where the DFB laser includes a first output facet and a second output facet. The first waveguide interferometer arm structure is coupled to the first output facet of the DFB laser, and the first output facet of the DFB laser emits the optical input signal to the first waveguide interferometer arm structure. The second waveguide interferometer arm structure is coupled to the second output facet of the DFB laser, and the second output facet of the DFB laser emits the optical input signal to the second waveguide interferometer arm structure.
