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…

Counterfactual quantum-information transfer without transmitting any physical particles
Unlike the typical teleportation, the present scheme can transport an unknown qubit in a nondeterministic manner without prior entanglement sharing or classical communication between the two distant participants.
From a Quantum Paradox to Counterportation
We uncover a new quantum paradox, where a simple question about two identical quantum systems reveals unsettlingly paradoxical answers when weak measurements are considered. Our resolution of the
From a Quantum Paradox to Provably Counterfactual Disembodied Transport: Counterportation
We uncover a new quantum paradox, where a simple question about two identical systems of nested interferometers reveals surprising answers on the whereabouts of a photon, when considering weak
Exchange unknown quantum states with almost invisible photons.
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 the
From Counterportation to Local Wormholes
Surprisingly, while such communication is intuitively explained in terms of “interaction-free” measurement and the Zeno effect, it is shown that neither is necessary, with far-reaching implications in support of an underlying physical reality.
How Quantum is Quantum Counterfactual Communication?
Quantum Counterfactual Communication is the recently-proposed idea of using quantum physics to send messages between two parties, without any matter/energy transfer associated with the bits sent.
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.
Counterfactual Full-Duplex Communication
The quantum duplex coding and quantum telexchanging protocols are demonstrated by exploiting counterfactual electron-photon interaction gates and shown to form full-duplex binary erasure channel and quantum erasure channels, respectively.
Quantum Duplex Coding
This work devise a distributed controlled NOT (DNOT) operation to transfer information in both directions at the same time to create a new form of full-duplex communication, called quantum duplex coding, that enables communicating parties to exchange either classical or quantum messages simultaneously and counterfactually by means of nonlocal controlled entanglement and/or disentanglement of the DNOT operation.
Modification of "Counterfactual communication protocols" which makes them truly counterfactual
A simple modification of these recent protocols eliminates the trace in the transmission channel and makes all these protocols truly counterfactual.


Deterministic quantum teleportation with atoms
Deterministic quantum-state teleportation between a pair of trapped calcium ions is reported, demonstrating unequivocally the quantum nature of the process.
Deterministic quantum teleportation of atomic qubits
Un unconditional teleportation of massive particle qubits using atomic (9Be+) ions confined in a segmented ion trap is reported, which achieves an average fidelity of 78 per cent, which exceeds the fidelity of any protocol that does not use entanglement.
Protocol for direct counterfactual quantum communication.
Using the "chained" quantum Zeno effect, this work shows how, in the ideal asymptotic limit, information can be transferred between Alice and Bob without any physical particles traveling between them.
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
Experimental quantum teleportation
It is shown that during teleportation, one of a pair of entangled photons are subjected to a measurement such that the second photon of the entangled pair acquires the polarization of the initial photon.
From classical state swapping to quantum teleportation
The quantum teleportation protocol is extracted directly out of a standard classical circuit that exchanges the states of two qubits using only controlled-NOT gates. This construction of

This Letter shows that the task of a secret key distribution can be accomplished even though a particle carrying secret information is not in fact transmitted through the quantum channel, and proposes protocols to implement this task.
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.
Quantum teleportation between light and matter
The teleportation of a quantum state between two single material particles (trapped ions) has now also been achieved and is demonstrated between objects of a different nature—light and matter, which respectively represent ‘flying’ and ‘stationary’ media.
Unconditional quantum teleportation
The first realization of unconditional quantum teleportation where every state entering the device is actually teleported is realized, using squeezed-state entanglement.
