Clean Quantum and Classical Communication Protocols


Clean Quantum and Classical Communication Protocols is a scholarly work by Christopher Perry and Matthias Christandl, published in 2016 in ''Physical Review Letters''. The main subjects of the publication include quantum, physics, quantum computing, quantum information science, and computer science. The authors present clean protocols for calculating the inner product of two n-bit strings, showing that (in the absence of preshared entanglement) at most n+3 qubits or n+O(sqrtn) bits of communication are required.
