The logic underlying the coherent nature of quantum information processing often deviates from intuitive reasoning, leading to surprising effects. Counterfactual computation constitutes a striking example: the potential outcome of a quantum computation can be inferred, even if the computer is not run. Relying on similar arguments to interaction-free measurements (or quantum interrogation), counterfactual computation is accomplished by putting the computer in a superposition of ‘running’ and… Expand

Universal quantum computation is usually associated with interaction among two-level quantum subsystems, as this interaction is commonly viewed as a necessity to achieve universal quantumExpand
Direct counterfactual communication via quantum Zeno effect
TLDR
By using the quantum Zeno effect and a single-photon source, direct communication without carrier particle transmission is implemented successfully and the feasibility of direct counterfactual communication is experimentally demonstrated with the current technique. Expand
A dynamical quantum Cheshire Cat effect and implications for counterfactual communication
TLDR
A type of dynamic effect is reported that is at the core of the so called "counterfactual computation" and especially " counterfactual communication" quantum effects that have generated a lot of interest recently, and generalizes the quantum Cheshire Cat effect to dynamical settings. Expand

It is striking that the quantum Zeno effect can be used to launch a direct counterfactual communication between two spatially separated parties, Alice and Bob. So far, existing protocols of this typeExpand
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 disembodiedExpand

We propose a quasi-counterfactual quantum swap gate for exchanging Alice's unknown photon state and Bob's unknown atomic state under the condition that only Alice's photon may appear in theExpand
Demonstrating Quantum Zeno Effect on IBM Quantum Experience
Quantum Zeno Effect (QZE) has been one of the most interesting phenomena in quantum mechanics ever since its discovery in 1977 by Misra and Sudarshan [J. Math. Phys. \textbf{18}, 756 (1977)]. ThereExpand
“Counterfactual” quantum protocols
TLDR
The counterfactuality of recently proposed protocols is analyzed and it is argued that an interaction-free measurement (IFM) of the presence of an opaque object can be named “counterfactual”, while proposed “ counterfactUAL” measurements of the absence of such objects are not counterfactual. Expand
