1. A device for managing one or more quantum nodes within a quantum network, the device comprising:
a processor configured to:
receive a first message, wherein the first message indicates (i) a first request to create a quantum connection between a source quantum network terminal (QNT) and a destination QNT, and (ii) a time to initiate creation of the quantum connection;
determine a quantum path for the quantum connection, wherein a first quantum network router (QNR) and a second QNR are associated with the quantum path, wherein the quantum path is determined based on (i) the first QNR having, at the indicated time, one or more first quantum capabilities satisfying at least one of one or more capability criteria (ii) and the second QNR having, at the indicated time, one or more second quantum capabilities satisfying at least one of the one or more capability criteria;
send a second message to one of the first and second QNRs, wherein the second message indicates a second request for the one of the first and second QNRs to create a first entangled qubit pair for a first hop of a quantum path and a second entanglement qubit pair for a second hop of the quantum path;
send a third message to the other one of the first and second QNRs, wherein the third message indicates a third request for the other one of the first and second QNRs to provide the quantum path by performing entanglement swapping using the first entangled qubit pair and the second entangled qubit pair; and
receive a confirmation message from the one of the first and second QNRs, wherein the confirmation message indicates that quantum connection has been created.
