Quantum information to the home [PDF]
A novel Raman-noise suppression scheme has enabled the first quantum key distribution (QKD) over a Gigabit-Ethernet PON carrying realistic data traffic. The DPSK-QKD system produced a sifted-key rate of 84kb/s with a Quantum-BER of 4%.

Quantum advantages for transportation tasks - projectiles, rockets and quantum backflow
Consider a scenario where a quantum particle is initially prepared in some bounded region of space and left to propagate freely. After some time, we verify if the particle has reached some distant target region.

Quantum Information Transfer between a Two-Level and a Four-Level Quantum System [PDF]
Quantum mechanics provides a disembodied way to transfer quantum information from one quantum object to another. In theory, this quantum information transfer can occur between quantum objects of any dimension, yet the reported experiments of quantum information transfer to date have mainly focused on the cases where the quantum objects have the same ...

Photonic quantum information processing: a review [PDF]
Photonic quantum technologies represent a promising platform for several applications, ranging from long-distance communications to the simulation of complex phenomena. Indeed, the advantages offered by single photons do make them the candidate of choice

Quantum-enhanced radiometry via approximate quantum error correction
Exotic quantum states can be advantageous for sensing, but are very fragile, so that some form of quantum error correction is needed. Here, the authors show how approximate QEC helps overcoming decoherence due to noise when measuring the excitation ...

Quantum Information Causality [PDF]
How much information can a transmitted physical system fundamentally communicate? We introduce the principle of quantum information causality, which states the maximum amount of quantum information that a quantum system can communicate as a function of its dimension, independently of any previously shared quantum physical resources.

Partial quantum information [PDF]
Information--be it classical or quantum--is measured by the amount of communication needed to convey it. In the classical case, if the receiver has some prior information about the messages being conveyed, less communication is needed. Here we explore the concept of prior quantum information: given an unknown quantum state distributed over two systems,

Relativistically invariant quantum information [PDF]
We show that quantum information can be encoded into entangled states of multiple indistinguishable particles in such a way that any inertial observer can prepare, manipulate, or measure the encoded state independent of their Lorentz reference frame ...
