Information Loss Pathways in a Numerically Exact Simulation of a non-Markovian Open Quantum System
Evgeny A. Polyakov, Alexey N. Rubtsov
In the non-Markovian regime, the bath has the memory about the past behavior of the open quantum system. This memory has slowly-decaying power-law tails. Such a long-range characte…
Dressed Quantum Trajectories: Novel Approach to the non-Markovian Dynamics of Open Quantum Systems on a Wide Time Scale
Evgeny A. Polyakov, Alexey N. Rubtsov
A new approach to the theory and simulation of the non-Markovian dynamics of open quantum systems is presented. It is based on identification of a parameter which is uniformly smal…
Quantum communication protocols as a benchmark for quantum computers
A. A. Zhukov, E. O. Kiktenko, A. A. Elistratov +2
We point out that realization of quantum communication protocols in programmable quantum computers provides a deep benchmark for capabilities of real quantum hardware. Particularly…
Entanglement of macroscopically distinct states of light
Demid V. Sychev, Valeriy A. Novikov, Khurram K. Pirov +2
Schrödinger's famous Gedankenexperiment has inspired multiple generations of physicists to think about apparent paradoxes that arise when the logic of quantum physics is applied to…
Overcoming inefficient detection in sub-shot-noise absorption measurement and imaging
E. Knyazev, F. Ya. Khalili, M. V. Chekhova
Photon-number squeezing and correlations enable measurement of absorption with an accuracy exceeding that of the shot-noise limit. However, sub-shot noise imaging and sensing based…
Error estimation at the information reconciliation stage of quantum key distribution
E. O. Kiktenko, A. O. Malyshev, A. A. Bozhedarov +3
Quantum key distribution (QKD) offers a practical solution for secure communication between two distinct parties via a quantum channel and an authentic public channel. In this work…
Security of quantum key distribution with detection-efficiency mismatch in the single-photon case: Tight bounds
M. K. Bochkov, A. S. Trushechkin
One of the challenges in practical quantum key distribution is dealing with efficiency mismatch between different threshold single-photon detectors. There are known bounds for the…
Probing the Tavis-Cummings level splitting with intermediate-scale superconducting circuits
Ping Yang, Jan David Brehm, Juha Leppäkangas +7
We demonstrate the local control of up to eight two-level systems interacting strongly with a microwave cavity. Following calibration, the frequency of each individual two-level sy…
Comment on "Inherent security of phase coding quantum key distribution systems against detector blinding attacks" [Laser Phys. Lett. 15, 095203 (2018)]
Aleksey Fedorov, Ilja Gerhardt, Anqi Huang +8
This is a brief comment on the Letter by Balygin and his coworkers [Laser Phys. Lett. 15, 095203 (2018)]. We point out an error that invalidates the Letter's conclusions.
Impact of detuning and dephasing on a laser-corrected subnatural-linewidth single-photon source
Juan Camilo López Carreño, Eduardo Zubizarreta Casalengua, Fabrice P. Laussy +1
The elastic scattering peak of a resonantly driven two-level system has been argued to provide narrow-linewidth antibunched photons. Although independent measurements of spectral w…
Quantum noise cancellation in asymmetric speed meters with balanced homodyne readout
T Zhang, E Knyazev, S Steinlechner +17
Sagnac speed meter (SSM) topology is known as an alternative technique to reduce quantum back-action in gravitational-wave interferometers. However, any potential imbalance of the…
Implementation vulnerabilities in general quantum cryptography
Anqi Huang, Stefanie Barz, Erika Andersson +1
Quantum cryptography is information-theoretically secure owing to its solid basis in quantum mechanics. However, generally, initial implementations with practical imperfections mig…
Homodyne-detector-blinding attack in continuous-variable quantum key distribution
Hao Qin, Rupesh Kumar, Vadim Makarov +1
We propose an efficient strategy to attack a continuous-variable quantum key distribution (CV-QKD) system, that we call homodyne detector blinding. This attack strategy takes advan…
Darkness of two-mode squeezed light in Λ-type atomic system
E. S. Moiseev, Arina Tashchilina, S. A. Moiseev +1
We show that, under certain circumstances, an optical field in a two-mode squeezed vacuum (TMSV) state can propagate through a lossy atomic medium without degradation or evolution.…
Non-adiabatic effects in periodically driven-dissipative open quantum systems
Viktor Reimer, Kim G. L. Pedersen, Niklas Tanger +2
We present a general method to calculate the quasi-stationary state of a driven-dissipative system coupled to a transmission line (and more generally, to a reservoir) under periodi…
Symmetry-protected coherent relaxation of open quantum systems
Moos van Caspel, Vladimir Gritsev
We compute the effect of Markovian bulk dephasing noise on the staggered magnetization of the spin-1/2 XXZ Heisenberg chain, as the system evolves after a Néel quench. For sufficie…
Joint subnatural-linewidth and single-photon emission from resonance fluorescence
Juan Camilo López Carreño, Eduardo Zubizarreta Casalengua, Fabrice P. Laussy +1
Resonance fluorescence---the light emitted when exciting resonantly a two-level system---is a popular quantum source as it seems to inherit its spectral properties from the driving…
Local Sensing with the Multi-Level AC Stark Effect
Andre Schneider, Jochen Braumüller, Lingzhen Guo +5
Analyzing weak microwave signals in the GHz regime is a challenging task if the signal level is very low and the photon energy widely undefined. A superconducting qubit can detect…
