Entanglement Swapping for Partially Entangled Qudits and the Role of Quantum Complementarity

Advanced Quantum Technologies, Volume 9, Issue 2, February 2026.
The entanglement swapping protocol is extended to partially entangled qudit states and analyzed through complete complementarity relations. Analytical bounds on the average distributed entanglement are established, showing how the initial local predictability and entanglement constrain the operational distribution.

Bidirectional Quantum Teleportation by Using Six-Qubit Cluster State

IEEE Access, 2019
Quantum teleportation is considered as the most basic process of quantum communication. It is undoubtedly beneficial for the realization of quantum teleportation while transmitting the maximum number of quantum bits with the minimum number of quantum ...

Electrically and Geometrically Tunable Photon Pair Entanglement from Ferroelectric Nematic Liquid Crystal

Advanced Science, Volume 13, Issue 3, 14 January 2026.
By exploiting the strong nonlinear optical response and controllable molecular ordering of ferroelectric nematic liquid crystals (FNLCs), these materials can serve as tunable sources of polarization‐entangled photons. Adjusting the sample geometry or applying an external electric field enables continuous control of the entanglement degree, advancing ...

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 ...

Monolithic Silicon Photonic Transceiver for 160 km Multi‐Channel Quantum Entanglement Distribution in Fiber Network

Laser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.
The paper demonstrates a chip scale (4.5 x 4.5 mm2) silicon integrated system that is capable of distributing entangled photons over 160 km single mode fibers without dispersion compensations and external optical filters. The results highlight the potential for massive production and large‐scale deployed quantum integrated circuits for a future ...

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

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,
