• Abstract: The enigma surrounding the existence of black holes has recently been substantiated through the groundbreaking work of experimental physicists \cite{genzel2024}. Exploring quantum systems under the gravitational influence of black holes has emerged as a pivotal area of research. Among the frontier works in quantum information processing is the utilization of quantum states as quantum channels. A fundamental quantum information protocol is teleportation, in which two parties, Alice and Bob, share entangled states. In this protocol, the sender, Alice, who holds an unknown qubit, utilizes local operations and classical communication (LOCC) to recreate the qubit at the recipient's (Bob's) end. Notably, during the execution of this protocol, Alice loses the unknown qubit on her side. The teleportation protocol, originally proposed by Bennett et al. \cite{bennett1993}, has been extensively studied with various states and under different physical setups. Researchers have explored both modifications to the protocol itself and the viability of various quantum states as teleportation channels. In this paper, we investigate whether bipartite mixed states derived from two inequivalent classes of tripartite pure states, subjected to the gravitational influence of two different black hole models, can still serve as efficient quantum channels for teleportation. We emphasize the teleportation fidelity of these states, a critical factor for determining their efficacy as quantum channels. Specifically, the fidelity must exceed the classical limit of $\frac{2}{3}$ to be considered effective \cite{pop1994}. We conjecture that, even under the gravitational influence of black holes, the quantum characteristics of the given states are preserved, enabling them to function effectively as quantum channels for teleportation.

  A test of quantumness is a protocol that allows a classical verifier to certify (only) that a prover is not classical. We show that tests of quantumness that follow a certain template, which captures recent proposals such as (Kalai et al., 2022) can in fact do much more. Namely, the same protocols can be used for certifying a qubit, a building-block that stands at the heart of applications such as certifiable randomness and classical delegation of quantum computation.

• Perfect teleportation with a partially entangled quantum channel [4.9395337334694105]
  Quantum teleportation provides a way to transfer unknown quantum states from one system to another via an entangled state as a quantum channel without physical transmission of the object itself. The entangled channel, measurement performed by the sender (Alice), and classical information sent to the receiver (Bob) are three key ingredients in the procedure, which need to cooperate with each other. We propose a scheme for perfect teleportation of a qubit through a high-dimensional quantum channel in a pure state with two equal largest Schmidt coefficients.
