The unique and often-weird properties of quantum mechanics allow an information carrier to propagate through multiple trajectories of quantum channels simultaneously. This ultimately leads us to quantum trajectories with an indefinite causal order of quantum channels. It has been shown that indefinite causal order enables the violation of bottleneck capacity, which bounds the amount of the transferable classical and quantum information through a classical trajectory with a well-defined causal…

(Causal)-Activation of Complex Entanglement Structures in Quantum Networks
TLDR
A novel generation scheme exhibiting two attractive features, namely, deterministically generating genuinely multipartite entangled states without requiring any direct interaction between the qubits, is designed.

Capacity Bounds for Quantum Communications through Quantum Trajectories
TLDR
This paper derives closed-form expressions for both the upper- and the lower-bound on the quantum capacity achievable via a quantum trajectory, and identifies the region where a quantum trajectories incontrovertibly outperforms the amount of transmissible information beyond the limits of conventional quantum Shannon theory.
Quantum Switch for the Quantum Internet: Noiseless Communications Through Noisy Channels
TLDR
The analysis reveals that, by utilizing the quantum switch, the quantum teleportation is heralded as a noiseless communication process with a probability that, remarkably and counter-intuitively, increases with the noise levels affecting the communication channels considered in the indefinite-order combination.
Communication Enhancement through Quantum Coherent Control of N Channels in an Indefinite Causal-Order Scenario
TLDR
A formalism to assess information transmission in the most general case of N channels in an indefinite causal order scenario yielding the output of such transmission is proposed and it is found that the transmission of information for three channels is twice that of transmission of the two-channel case when a full superposition of all possible causal orders is used.
Entanglement required in achieving entanglement-assisted channel capacities
Entanglement shared between the two ends of a quantum-communication channel has been shown to be a useful resource in increasing both the quantum and classical capacities for these channels. The
Entanglement-Assisted Classical Capacity of Noisy Quantum Channels
Prior entanglement between sender and receiver, which exactly doubles the classical capacity of a noiseless quantum channel, can increase the classical capacity of some noisy quantum channels by an
Quantum communication in a superposition of causal orders
TLDR
It is shown that entanglement can enhance the ability to transmit quantum information over noisy communication channels and, when the two channels are traversed in an indefinite order, a quantum bit sent through them has a 25% probability to reach the receiver without any error.
Fundamental limits of repeaterless quantum communications
TLDR
The fundamental rate-loss tradeoff affecting any protocol of quantum key distribution is determined, which sets the limits of point-to-point quantum communications and provides precise and general benchmarks for quantum repeaters.
Communication through coherent control of quantum channels
TLDR
This work shows that, when quantum channels are controlled coherently, information about their specific implementation is accessible in the output state of the joint control-target system and allows two different implementations of what is usually considered to be the same channel to therefore be differentiated.
When Entanglement Meets Classical Communications: Quantum Teleportation for the Quantum Internet
TLDR
This manuscript is to shed light on quantum teleportation to appreciate the fundamental differences between the transmission of classical information versus the teleportation of quantum information, and to understand the communications functionalities underlying quantum teleportation.
Trading classical communication, quantum communication, and entanglement in quantum Shannon theory
TLDR
A “unit-resource” capacity theorem is proved that applies to the scenario where only the above three noiseless resources are available for consumption or generation, and the optimal strategy mixes the three fundamental protocols of teleportation, superdense coding, and entanglement distribution.
