We present an interaction-free measurement with quantum Zeno effect and a high efficiency η = 74.6% ± 0.15%. As a proof-of-principle demonstration, this measurement can be used to implement a quantum counterfactual-like communication protocol. Instead of a single photon state, we use a coherent light as the input source and show that the output agrees with the proposed quantum counterfactual communication protocol according to Salih et al. Although the counterfactuality is not achieved due to… 
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
Modification of "Counterfactual communication protocols" which makes them truly counterfactual
TLDR
A simple modification of these recent protocols eliminates the trace in the transmission channel and makes all these protocols truly counterfactual.
Improvement of reliability in multi-interferometer-based counterfactual deterministic communication with dissipation compensation.
TLDR
This work simulates and test this counterfactual deterministic communication protocol with a finite number of interferometers, and demonstrates the improvement of the reliability using dissipation compensation in interferometer.
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
Information carrier and resource optimization of counterfactual quantum communication
TLDR
This paper optimization the resource efficiency of the counterfactual quantum communication in terms of the number of channels used, time consumed to transmit 1-bit classical information between two remote parties, and the numberof qubits required to accomplish the counter Factual quantum Communication.
Do the laws of physics prohibit counterfactual communication?
TLDR
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.
Counterfactual Bell-State Analysis
TLDR
This counterfactual analysis not only enables us to perform a complete Bell-state analysis, but also enables spatially separated parties to distinguish between the four Bell states without transmitting any physical particle over the channel.
Analysis of counterfactuality of counterfactual communication protocols
TLDR
This protocol and its modification are used as a test bed for analysis of meaning ofcounterfactuality to clarify the counterfactuality status of various counterfactual proposals.
Quantum Secure Group Communication
We propose a quantum secure group communication protocol for the purpose of sharing the same message among multiple authorized users. Our protocol can remove the need for key management that is
Counterfactual communication
Counterfactual communication, transferring bits and even qubits without particle travelling in the transmission channel is a bizarre quantum effect. It is also a very controversial topic. Here I will

TLDR
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.
Asking photons where they have been.
TLDR
From the analysis, it is concluded that the past of the photons is not represented by continuous trajectories, although a "common sense" analysis adopted in various welcher weg measurements, delayed-choice which-path experiments, and counterfactual communication demonstrations yields a single trajectory.

TLDR
This work discusses quantum cryptographic protocols based on the transmission of weak coherent states and presents a system, based on a symbiosis of two existing systems, for which the information available to the eavesdropper is significantly reduced and is therefore safer than the two previous ones.
