Quantum teleportation using non-orthogonal entangled channels
, 2010 We study quantum teleportation with the resource of non-orthogonal qubit states. We first extend the standard teleportation protocol to the case of such states. We investigate how the loss of teleportation fidelity resulting for the use of non-orthogonal

All entangled states can demonstrate non-classical teleportation [PDF]
, 2017 Quantum teleportation, the process by which Alice can transfer an unknown quantum state to Bob by using pre-shared entanglement and classical communication, is one of the cornerstones of quantum information.

Two‐Photon Interference from an InAs Quantum Dot Emitting in the Telecom C‐Band
Advanced Quantum Technologies, EarlyView.A telecom C‐band emitting quantum dot integrated with a circular Bragg grating cavity demonstrates two‐photon interference visibility of 71.9%, which is currently state‐of‐art. The improved two‐photon interference visibility is enabled by optimized growth and Purcell enhancement.

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

Quantum Circuit Design using a Progressive Widening Enhanced Monte Carlo Tree Search
Advanced Quantum Technologies, EarlyView.This article proposes the Progressive Widening enhanced Monte Carlo Tree Search (PWMCTS) to design parameterized quantum circuits. It improves the efficiency of the previous MCTS‐based techniques in terms of number of quantum circuit evaluation, number of gates and CNOT count.

Adiabatic Gate Teleportation [PDF]
Physical Review Letters, 2009 The difficulty in producing precisely timed and controlled quantum gates is a significant source of error in many physical implementations of quantum computers. Here we introduce a simple universal primitive, adiabatic gate teleportation, which is robust to timing errors and many control errors and maintains a constant energy gap throughout the ...

Discriminating quantum correlations with networking quantum teleportation
Physical Review Research, 2020 The Bell inequality, and its substantial experimental violation, offers a seminal paradigm for showing that the world is not in fact locally realistic.

Entanglement and Teleportation in Bipartite System [PDF]
, 2009 We present a mathematical formulation of old teleportation protocol (original teleportation protocol introduced by Bennett et.al.) for mixed states and study in detail the role of mixedness of the two qubit quantum channel in a teleportation protocol. We

Experimental Quantum Teleportation of a Two-Qubit Composite System
, 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.

Advanced Quantum Technologies, EarlyView.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.
