We propose an experimental realisation of the protocol for the counterfactual disembodied transport of an unknown qubit---or what we call counterportation---where sender and receiver, remarkably, exchange no particles. We employ cavity quantum electrodynamics, estimating resources for beating the classical fidelity limit---except, unlike teleportation, no pre-shared entanglement nor classical communication are required. Our approach is multiple orders of magnitude more efficient in terms of…

The laws of physics do not prohibit counterfactual communication

It has been conjectured that counterfactual communication is impossible, even for post-selected quantum particles. We strongly challenge this by proposing precisely such a counterfactual scheme



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

Direct counterfactual communication via quantum Zeno effect

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.

Counterfactual quantum computation through quantum interrogation

This work shows how to boost the counterfactual inference probability to unity, thereby beating the random guessing limit and implementing Grover's search algorithm with an all-optical approach, and can eliminate errors induced by decoherence.

Deterministic Teleportation and Universal Computation Without Particle Exchange

The controlled-phase universal gate is proposed, where no particles are exchanged between control and target, allows complete Bell detection among two remote parties, and is experimentally feasible.

What Is Nonlocal in Counterfactual Quantum Communication?

It is shown that a locally conserved, massless current-specifically, a current of modular angular momentum, L_{z} mod 2ℏ-carries the one bit of information.

Counterfactual entanglement distribution without transmitting any particles.

A counterfactual protocol for entanglement distribution against the traditional forms, that is, two distant particles can be entangled with no physical particles travel between the two remote participants, is proposed.

Do the laws of physics prohibit counterfactual communication?

This paper proposes exactly such a counterfactual scheme where, unambiguously, none of Alice's photons that make it has been to Bob, and demonstrates counterfactuality experimentally by means of weak measurements, as well as conceptually using consistent histories.

Comment on "Particle Path Through a Nested Mach-Zehnder Interferometer"

In a recent paper, arXiv:1604.04596, Griffiths questioned - based on an informative consistent-histories (CH) argument - the counterfactuality, for one of the bit choices, of Salih et al.'s protocol

A quantum gate between a flying optical photon and a single trapped atom

The development of a robust two-qubit gate that allows the linking of distant computational nodes is “a pressing challenge” and here it is demonstrated between the spin state of a single trapped atom and the polarization state of an optical photon contained in a faint laser pulse.

Teleporting an unknown quantum state via dual classical and Einstein-Podolsky-Rosen channels.

An unknown quantum state \ensuremath{\Vert}\ensuremath{\varphi}〉 can be disassembled into, then later reconstructed from, purely classical information and purely nonclassical Einstein-Podolsky-Rosen
