- Authors: Nayana Das, Goutam Paul
- Abstract summary: A Measurement Device Independent Quantum Dialogue protocol has been proposed (Quantum Information Processing 16.12: 305) in 2017.
We first generalize this protocol to a three-party quantum conference and then to a multi-party quantum conference.
We also propose a protocol for quantum multi-party XOR computation.

- Abstract: Quantum conference is a process of securely exchanging messages between three
or more parties, using quantum resources. A Measurement Device Independent
Quantum Dialogue (MDI-QD) protocol, which is secure against information
leakage, has been proposed (Quantum Information Processing 16.12 (2017): 305)
in 2017, is proven to be insecure against intercept-and-resend attack strategy.
We first modify this protocol and generalize this MDI-QD to a three-party
quantum conference and then to a multi-party quantum conference. We also
propose a protocol for quantum multi-party XOR computation. None of these three
protocols proposed here use entanglement as a resource and we prove the
correctness and security of our proposed protocols.

A proof of quantumness is an efficiently verifiable interactive test that an efficient quantum computer can pass.
Existing single-round protocols require large quantum circuits, whereas multi-round ones use smaller circuits but require experimentally challenging mid-circuit measurements.
We construct efficient single-round proofs of quantumness based on existing knowledge assumptions.

Quantum secure direct communication (QSDC) uses the quantum channel to transmit information reliably and securely.
In order to eliminate the security loopholes resulting from practical detectors, the measurement-device-independent (MDI) QSDC protocol has been proposed.
We propose a single-photon-memory MDI QSDC protocol (SPMQC) for dispensing with high-performance quantum memory.

We propose a new concept, oblivious computation quantum computation, where secrecy of the input qubits and the program to identify the quantum gates are required.
Exploiting quantum teleportation, we propose a two-server protocol for this task.
Also, we discuss delegated multiparty quantum computation, in which, several users ask multiparty quantum computation to server(s) only using classical communications.

Quantum conference key agreement (QCKA) allows multiple users to establish a secure key from a shared multi-partite entangled state.
In a quantum network, this protocol can be efficiently implemented using a single copy of a N-qubit Greenberger-Horne-Zeilinger (GHZ) state to distil a secure N-user conference key bit.
