Signifying quantum benchmarks for qubit teleportation and secure communication using Einstein-Podolsky-Rosen steering inequalities

, 2013
The demonstration of quantum teleportation of a photonic qubit from Alice to Bob usually relies on data conditioned on detection at Bob's location. I show that Bohm's Einstein-Podolsky-Rosen (EPR) paradox can be used to verify that the quantum benchmark ...

General Gate Teleportation and the Inner Structure of Its Clifford Hierarchies

Mathematical Methods in the Applied Sciences, Volume 48, Issue 17, Page 15985-15997, 30 November 2025.
ABSTRACT The quantum gate teleportation mechanism allows for the fault‐tolerant implementation of “Clifford hierarchies” of gates assuming, among other things, a fault‐tolerant implementation of the Pauli gates. We discuss how this method can be extended to assume the fault‐tolerant implementation of any orthogonal unitary basis of operators, in such a

High‐Purity Single‐Photon Emission in the Telecom O‐Band from Droplet‐Epitaxy InAs Quantum Dots Integrated into a GaAs/AlGaAs Planar Microcavity on Vicinal GaAs(111)A Platform

Advanced Quantum Technologies, Volume 8, Issue 11, November 2025.
High‐purity single‐photon emission at telecom O‐band is demonstrated from droplet‐epitaxy InAs quantum dots embedded in a GaAs/AlGaAs microcavity. Strain engineering via an InAlAs buffer enables broadband telecom emission with high purity, short lifetimes, and enhanced extraction.

Holographic limitations and corrections to quantum information protocols

Physical Review Research
We discuss the limitations imposed on entanglement distribution, quantum teleportation, and quantum communication by holographic bounds, such as the Bekenstein bound and Susskind's spherical entropy bound. For continuous-variable (CV) quantum information,

Quantum teleportation from light beams to vibrational states of a macroscopic diamond

Nature Communications, 2016
Quantum teleportation has found important applications in quantum technologies, but pushing it to macroscopic objects is challenging because of the fragility of quantum states. Here, the authors demonstrate teleportation of states from light beams to the

Entanglement Teleportation Through 1D Heisenberg Chain

, 2005
Information transmission of two qubits through two independent 1D Heisenberg chains as a quantum channel is analyzed. It is found that the entanglement of two spin-$\frac 12$ quantum systems is decreased during teleportation via the thermal mixed state ...

Analysis of the Effect of Entanglement Operators and the Scalability of Players’ Payoff Computation in N‐Player Quantum Games

Advanced Quantum Technologies, Volume 8, Issue 11, November 2025.
A new set of entanglement operators for N‐player quantum games is introduced, and their effects on each player's behavior throughout the game are explored. The hardware efficiency of the entanglement operators is assessed against state‐of‐the‐art quantum games in terms of circuit depth and fidelity.

Optimal Control-Assisted Rapid Quantum State Transfer on 1-D Spin Chain

IEEE Transactions on Quantum Engineering
Traditional many-body teleportation relies on the strong interaction property of a quantum many-body system, which usually requires numerous qubits and entanglement resources, making it difficult to realize experimentally.

Optimal conclusive teleportation of quantum states

, 2003
Quantum teleportation of qudits is revisited. In particular, we analyze the case where the quantum channel corresponds to a non-maximally entangled state and show that the success of the protocol is directly related to the problem of distinguishing non ...
