Concealed quantum telecomputation for anonymous 6G URLLC networks
Distributed learning and multi-tier computing are the key ingredients to ensure ultra-reliable
and low-latency communication (URLLC) in 6G networks. The distinct transition from …

The wave function as a true ensemble
JR Hance, S Hossenfelder - Proceedings of the Royal …, 2022 - royalsocietypublishing.org
In quantum mechanics, the wave function predicts probabilities of possible measurement
outcomes, but not which individual outcome is realized in each run of an experiment. This …

[HTML][HTML] How quantum is quantum counterfactual communication?
Abstract Quantum Counterfactual Communication is the recently-proposed idea of using
quantum physics to send messages between two parties, without any matter/energy transfer …

[HTML][HTML] Counterfactual ghost imaging
We give a protocol for ghost imaging in a way that is always counterfactual—while imaging
an object, no light interacts with that object. This extends the idea of counterfactuality beyond …

Deterministic teleportation and universal computation without particle exchange
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 of …

Three approaches for analyzing the counterfactuality of counterfactual protocols
Counterfactual communication protocols are analyzed using three approaches: a classical
argument, the weak trace criterion, and the Fisher information criterion. It is argued that the …

Weak values and the past of a quantum particle
We investigate four key issues with using a nonzero weak value of the spatial projection
operator to infer the past path of an individual quantum particle. First, we note that weak …

[PDF][PDF] Do the laws of physics prohibit counterfactual communication
It has been conjectured that counterfactual communication is impossible, even for post-
selected quantum particles. We strongly challenge this by proposing exactly such a …

From counterportation to local wormholes
H Salih - Quantum Science and Technology, 2023 - iopscience.iop.org
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 …
