implements Entanglement Routing Introduction This protocol [1] implements the task of distributing arbitrary graph states over quantum networks of arbitrary topology. The goal is to distribute these states in a way that is most efficient in terms of the number of Bell pairs consumed and the number of operations realised by the protocol.   Related…

implements Anonymous Transmission Introduction This example protocol implements the task of Anonymous Transmission in a multi-node quantum network. The protocol uses an untrusted $n$-partite GHZ state to enable two nodes, Sender and Receiver, to establish a link which they use to transmit a quantum message. In addition to adversarial nodes, the source of the GHZ…

implements Anonymous Transmission Introduction This protocol is a subroutine that allows the anonymous distribution of a GHZ state between $m+1$ parties, starting from an $n$-party GHZ state. It is used in the protocol: Anonymous Conference Key Agreement using GHZ states Related Paper(s) Anonymous quantum conference key agreement Outline The entanglement source generates and distributes sufficient…

implements Quantum Conference Key Agreement Introduction This protocol achieves the functionality of quantum conference key agreement. This protocol allows multiple parties in a quantum network to establish a shared secret key anonymously. Related Paper(s) Anonymous Conference Key Agreement in Quantum Networks Outline First, the sender notifies each receiver in the network anonymously The entanglement source…

implements Anonymous Transmission Introduction This protocol implements the task of Anonymous Transmission in a multiple node quantum network. The protocol uses $n$-partite GHZ state to enable two nodes, sender and receiver, to establish a link which they use to transmit a quantum message. Importantly, the quantum message is transmitted in a way that the identity…

implements Quantum Encryption with Certified Deletion Introduction This protocol implements the functionality of Quantum Encryption with Certified Deletion using single-qubit state preparation and measurement. This scheme is limited to the single-use, private-key setting. Related Paper(s) Quantum encryption with certified deletion Outline The scheme consists of 5 circuits: Key: This circuit generates the key used in…
