Entanglement and teleportation between polarization and wave-like encodings of an optical qubit
Demid V. Sychev, Alexander E. Ulanov, Anastasia A. Pushkina +3
Light is an irreplaceable means of communication among various quantum information processing and storage devices. Due to their different physical nature, some of these devices cou…
Quantum-secured data transmission in urban fibre-optic communication lines
A. V. Duplinskiy, E. O. Kiktenko, N. O. Pozhar +8
Quantum key distribution (QKD) provides theoretic information security in communications based on the laws of quantum physics. In this work, we report an implementation of quantum-…
Light Scattering From an Atomic Array Trapped Near a One-Dimensional Nanoscale Waveguide: a Microscopic Approach
V. A. Pivovarov, A. S. Sheremet, L. V. Gerasimov +4
The coupling of atomic arrays and one-dimensional subwavelength waveguides gives rise to in- teresting photon transport properties, such as recent experimental demonstrations of la…
Quantum simulation of the spin-boson model with a microwave circuit
Juha Leppäkangas, Jochen Braumüller, Melanie Hauck +7
We consider superconducting circuits for the purpose of simulating the spin-boson model. The spin-boson model consists of a single two-level system coupled to bosonic modes. In mos…
Decoy state quantum key distribution with imperfect source
Anqi Huang, Shi-Hai Sun, Zhihong Liu +1
The decoy state protocol has been considered to be one of the most important methods to protect the security of quantum key distribution (QKD) with a weak coherent source. Here we…
Overcoming the SQL in gravitational wave detectors using spin systems with negative effective mass
Farid Khalili, Eugene S. Polzik
Quantum back action (QBA) of a measurement limits the precision of observation of the motion of a free mass. This profound effect dabbed the "Heisenberg microscope" in the early da…
Engineering the Optical Spring via Intra-Cavity Optical-Parametric Amplification
Mikhail Korobko, Farid Ya. Khalili, Roman Schnabel
The 'optical spring' results from dynamical back-action and can be used to improve the sensitivity of cavity-enhanced gravitational-wave detectors. The effect occurs if an oscillat…
Quantum tomography enhanced through parametric amplification
E. Knyazev, K. Yu. Spasibko, M. V. Chekhova +1
Quantum tomography is the standard method of reconstructing the Wigner function of quantum states of light by means of balanced homodyne detection. The reconstruction quality stron…
An argon ion beam milling process for native layers enabling coherent superconducting contacts
Lukas Grünhaupt, Uwe von Lüpke, Daria Gusenkova +8
We present an argon ion beam milling process to remove the native oxide layer forming on aluminum thin films due to their exposure to atmosphere in between lithographic steps. Our…
Detection loss tolerant supersensitive phase measurement with an SU(1,1) interferometer
Mathieu Manceau, Gerd Leuchs, Farid Khalili +1
In an unseeded SU(1,1) interferometer composed of two cascaded degenerate parametric amplifiers, with direct detection at the output, we demonstrate a phase sensitivity overcoming…

We report the results of the implementation of a quantum key distribution (QKD) network using standard fibre communication lines in Moscow. The developed QKD network is based on th…
Symmetric blind information reconciliation and hash-function-based verification for quantum key distribution
A. K. Fedorov, E. O. Kiktenko, A. S. Trushechkin
We consider an information reconciliation protocol for quantum key distribution (QKD). In order to correct down the error rate, we suggest a method, which is based on symmetric bli…
Photon Correlations from the Mollow Triplet
Juan Camilo López Carreño, Elena del Valle, Fabrice P. Laussy
Photon correlations between the photoluminescence peaks of the Mollow triplet have been known for a long time, and recently hailed as a resource for heralded single-photon sources.…
