Implement a simulation for MDI-QKD

1

Similar to the other QKD protocols that have been implemented already, implement a simulation of MDI-QKD: https://arxiv.org/abs/1109.1473

Use multiple queues (one per connection) for better parallelization in the network layer since currently there is just one queue for the entire network.

4

Currently the Network component has a single packet queue in which all Host packets arrive. They are processed in FIFO order. This may cause congestion if some parts of the...

Deprecate `add_data_qubit` to `add_qubit`

1

Currently, the Host method `add_data_qubit` is named poorly. We should rename it to just `add_qubit`.

Implement an example of a second generation quantum repeater

19

A first generation quantum repeater uses entanglement swapping to establish quantum entanglement between two parties not directly connected. A second generation quantum repeater uses heralded quantum entanglement and error correction....

Implement a multi-node QKD network

9

Implement a trusted node QKD network simulation with at least 1 trusted node.

Currently when one sets the error probability for an X or Z error in the Network, it is applied to each channel the same way. This should be a property...

For the QuTip backend it would be helpful to get the density matrix of multiple qubits and not just one

1

In the QuTip backend, current the the `density_operator` method takes one qubit at a time. This prevents getting the density matrix of a joint system. This can be easily modified...

Adding connections to a host in the network should also update the network

1

**Describe the solution you'd like** If a host is in the network (i.e. already added), and the connections change (i.e. a connection is added or removed) it should reflect in...

Adds the ability to "wait for n" qubits.
