Iterated Gate Teleportation and Blind Quantum Computation.
Blind quantum computation allows a user to delegate a computation to an untrusted server while keeping the computation hidden. A number of recent works have sought to establish bounds on the communication requirements necessary to implement blind computation, and a bound based on the no-programming theorem of Nielsen and Chuang has emerged as a natural limiting factor. Here we show that this co...
متن کاملReversible logic gate using adiabatic superconducting devices
Reversible computing has been studied since Rolf Landauer advanced the argument that has come to be known as Landauer's principle. This principle states that there is no minimum energy dissipation for logic operations in reversible computing, because it is not accompanied by reductions in information entropy. However, until now, no practical reversible logic gates have been demonstrated. One of...
متن کاملExperimental teleportation of a quantum controlled-NOT gate.
Teleportation of quantum gates is a critical step for the implementation of quantum networking and teleportation-based models of quantum computation. We report an experimental demonstration of teleportation of the prototypical quantum controlled-NOT (CNOT) gate. Assisted with linear optical manipulations, photon entanglement produced from parametric down-conversion, and postselection from the c...
متن کاملGate teleportation using Series entanglement distributions on arbitrary remote states
The counter-intuitive and one of the most striking features of the quantum world is entanglement, which has found practical use in the eld of communication and cryptography. Various quantum communication protocols, like qubit teleportation, superdense coding, quantum information splitting, secret sharing, remote state preparation have been theoretically and experimentally demonstrated through e...
متن کاملErasure versus teleportation scheme of optical CNOT gate
We clarify the connections between the erasure scheme of probabilistic CNOT gate implementation recently proposed by Pittman, Jacobs and Franson [Phys. Rev. A 64, 062311 (2001)] and quantum teleportation.
