Experimental optical phase measurement approaching the exact Heisenberg limit

Nature Communications, 2018
Measurements of an unknown optical phase have not yet been performed with the ultimate precision, i.e. saturating the Heisenberg limit. Here, Daryanoosh et al.

CollComm: Enabling Efficient Collective Quantum Communication Based on EPR buffering [PDF]

arXiv, 2022
The noisy and lengthy nature of quantum communication hinders the development of distributed quantum computing. The inefficient design of existing compilers for distributed quantum computing worsens the situation. Previous compilation frameworks couple communication hardware with the implementation of expensive remote gates.

Experimental Implementation of Enhanced Security Coherent One-Way Quantum Key Distribution

IEEE Access
Coherent One-Way (COW) is a simple and widely utilized quantum key distribution (QKD) protocol, favored in both experimental and commercial applications. In this paper, we compare the information that an eavesdropper, Eve, can acquire in both the 2-decoy

Stealth Communication: Zero-Power Classical Communication, Zero-Quantum Quantum Communication and Environmental-Noise Communication

, 2005
An alternative physical way of communication, communication by the inherent background noise, is proposed which does not need net energy transfer in the information channel.

Quantum process tomography of a high-dimensional quantum communication channel [PDF]

Quantum, 2018
The characterization of quantum processes, e.g. communication channels, is an essential ingredient for establishing quantum information systems. For quantum key distribution protocols, the amount of overall noise in the channel determines the rate at ...

Relativistic Bohmian trajectories of photons via weak measurements

Nature Communications, 2022
Making Bohmian mechanics fully compatible with special relativity is still an ongoing challenge. Here, the authors make a further step in this direction by providing a way of constructing the relativistic Bohmian-type velocity field of single photons ...

Anonymous quantum communication

, 2007
We present the first protocol for the anonymous transmission of a quantum state that is information-theoretically secure against an active adversary, without any assumption on the number of corrupt participants.

Causal order as a resource for quantum communication [PDF]

Physical Review A, 2019
In theories of communication, it is usually presumed that the involved parties perform actions in a fixed causal order. However, practical and fundamental reasons can induce uncertainties in the causal order.
