Gravitationally Induced Entanglement Across an Event Horizon
Hatim Salih
It has long been assumed that a particle--having crossed a black hole event horizon unentangled with another particle in the exterior universe--can no longer dynamically entangle w…
Reply to "Counterfactual communication not achieved yet -- A Comment on Salih et al. (2022)"
Hatim Salih, Jonte R. Hance, Will McCutcheon +1
In his Comment on our recent paper ``The laws of physics do not prohibit counterfactual communication'', \textit{npj Quantum Information} (2022) 8:60, Popescu argues that the claim…
Deterministic Teleportation and Universal Computation Without Particle Exchange
Hatim Salih, Jonte R. Hance, Will McCutcheon +2
Teleportation is a cornerstone of quantum technologies, and has played a key role in the development of quantum information theory. Pushing the limits of teleportation is therefore…
Exchange-Free Computation on an Unknown Qubit at a Distance
Hatim Salih, Jonte R. Hance, Will McCutcheon +2
We present a way of directly manipulating an arbitrary qubit, without the exchange of any particles. This includes as an application the exchange-free preparation of an arbitrary q…
From Counterportation to Local Wormholes
Hatim Salih
We propose an experimental realisation of the protocol for the counterfactual disembodied transport of an unknown qubit -- or what we call counterportation -- where sender and rece…
The laws of physics do not prohibit counterfactual communication
Hatim Salih, Will McCutcheon, Jonte Hance +1
It has been conjectured that counterfactual communication is impossible, even for post-selected quantum particles. We strongly challenge this by proposing precisely such a counterf…
Comment on "Particle Path Through a Nested Mach-Zehnder Interferometer"
Hatim Salih
In a recent paper, arXiv:1604.04596, Griffiths questioned - based on an informative consistent-histories (CH) argument - the counterfactuality, for one of the bit choices, of Salih…
Counterfactual quantum erasure: spooky action without entanglement
Hatim Salih
We combine the eyebrow-raising quantum phenomena of erasure and counterfactuality for the first time, proposing a simple yet unusual quantum eraser: A distant Bob can decide to era…
Quantum Erasure Cryptography
Hatim Salih
The phenomenon of quantum erasure has long intrigued physicists, but has surprisingly found limited practical application. Here, we propose an erasure-based protocol for quantum ke…
Reply to "Comment on Protocol for Direct Counterfactual Quantum Communication"
Hatim Salih, Zheng-Hong Li, M. Al-Amri +1
In reply to Vaidman's Comment [arXiv:1304.6689], we show that his claim that our Protocol for Direct Counterfactual Quantum Communication [PRL 110, 170502 (2013), arXiv:1206.2042]…
Tripartite Counterfactual Quantum Cryptography
Hatim Salih
We show how two distrustful parties, "Bob" and "Charlie", can share a secret key with the help of a mutually trusted "Alice", counterfactually - that is with no information-carryin…
Protocol for Counterfactually Transporting an Unknown Qubit
Hatim Salih
Quantum teleportation circumvents the uncertainty principle using dual channels: a quantum one consisting of previously-shared entanglement, and a classical one, together allowing…
Comment on "Asking Photons Where Have They Been"
Hatim Salih
We argue that, in the recent letter by A. Danan et al. [PRL 111, 240402 (2013), arXiv:1304.7469], if weak measurements are performed such that complete destructive interference is…
Protocol for direct counterfactual quantum communication
Hatim Salih, Zheng-Hong Li, M. Al-Amri +1
It has long been assumed in physics that for information to travel between two parties in empty space, "Alice" and "Bob", physical particles have to travel between them. Here, usin…
