Multiparty Delegated Quantum Computing
Quantum computing has seen tremendous progress in the past few years. However, due to limitations in the scalability of quantum technologies, it seems that we are far from constructing universal quantum computers for everyday users. A more feasible solution is the delegation of computation to powerful quantum servers on the network. This solution was proposed in previous studies of blind quantu...
متن کاملQuantum-enhanced secure delegated classical computing
We present a family of quantumly-enhanced protocols to achieve unconditionally secure delegated classical computation where the client and the server have both their classical and quantum computing capacity limited. We prove the same task cannot be achieved using only classical protocols. This extends the work of Anders and Browne on the computational power of correlations to a security setting...
متن کاملMultiparty Quantum Signatures Schemes
Digital signatures are important cryptographic building-blocks that are widely used to provide security in electronic communications. They achieve three main cryptographic goals: authentication, non-repudiation, and transferability. These properties make them suitable for securing important tasks such as financial transactions, software updates, and legal contracts. When quantum communication i...
متن کاملMultiparty Quantum Communication Complexity
Quantum entanglement cannot be used to achieve direct communication between remote parties, but it can reduce the communication needed for some problems. Let each of k parties hold some partial input data to some fixed k-variable function f . The communication complexity of f is the minimum number of classical bits required to be broadcasted for every party to know the value of f on their input...
متن کاملMultiparty Quantum Secret Sharing
Based on a quantum secure direct communication (QSDC) protocol [Phys. Rev. A69(04)052319], we propose a (n, n)-threshold scheme of multiparty quantum secret sharing of classical messages (QSSCM) using only single photons. We take advantage of this multiparty QSSCM scheme to establish a scheme of multiparty secret sharing of quantum information (SSQI), in which only all quantum information recei...
