High-Fidelity Teleportation of Independent Qubits [PDF]

open access: yes, 1999
Quantum teleportation is one of the essential primitives of quantum communication. We suggest that any quantum teleportation scheme can be characterized by its efficiency, i.e. how often it succeeds to teleport, its fidelity, i.e.

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

open access: yesLaser &Photonics Reviews, EarlyView.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Continuous variable quantum teleportation of a thermal state in a thermal environment

open access: yesResults in Physics, 2022
The analytical formula for the fidelity of teleportation from Alice to Bob of a thermal state used as an input state is derived using the characteristic function approach. As a resource state it is used a continuous-variable two-mode bosonic state shared

No-cloning theorem and teleportation criteria for quantum continuous variables [PDF]

open access: yes, 2000
We discuss the criteria presently used for evaluating the efficiency of quantum teleportation schemes for continuous variables. Using an argument based upon the difference between 1-to-2 quantum cloning (quantum duplication) and 1-to-infinity cloning ...

Enhancing Cloud‐Based Healthcare Security With Quantum‐Secure HealthChain: A Quantum Computing and Blockchain Integrated Framework

open access: yesHealth Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background and Aims Rising quantum hazards and flaws in conventional encryption make cloud‐based healthcare data security harder. Quantum‐Secure HealthChain, a new architecture using blockchain and quantum computing, improves medical data security, patient privacy, and data fidelity. Methods To prevent quantum attacks, the proposed system uses

Universal Entanglement and an Information‐Complete Quantum Theory

open access: yesAdvanced Physics Research, Volume 5, Issue 4, April 2026.
This Perspective summarize an informationcomplete quantum theory which describes a fully quantum world without any classical systems and concepts. Here spacetime/gravity, having to be a physical quantum system, universally entangles matter (matter fermions and their gauge fields) as an indivisible trinity, and encodes information‐complete physical ...

Would the fidelity of quantum teleportation be increased by a local filtering operation near a dilaton black hole under decoherence?

open access: yesEuropean Physical Journal C: Particles and Fields
Previous studies have shown that the effects of black holes and environmental decoherence generally negatively influence quantum correlations and the fidelity of quantum teleportation in curved spacetime.

Experimental Quantum Teleportation of a Two-Qubit Composite System

open access: yes, 2006
Quantum teleportation, a way to transfer the state of a quantum system from one location to another, is central to quantum communication and plays an important role in a number of quantum computation protocols.
