Protocol for Counterfactually Transporting an Unknown Qubit

Quantum teleportation circumvents the uncertainty principle using dual channels: a quantum one consisting of previously-shared entanglement, and a classical one, together allowing the disembodied transport of an unknown quantum state over distance. It has recently been shown that a classical bit can be counterfactually communicated between two parties in empty space, “Alice” and “Bob.” Here, by using our “dual” version of the chained quantum Zeno effect to achieve a counterfactual CNOT gate, we… CONTINUE READING
