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…
Two-level masers as heat-to-work converters
A. Ghosh, D. Gelbwaser-Klimovsky, W. Niedenzu +4
Heat engines, which cyclically transform heat into work, are ubiquitous in technology. Lasers and masers, which generate a coherent electromagnetic field, may be viewed as heat eng…
Fluxon-Based Quantum Simulation in Circuit QED
Alexandru Petrescu, Hakan E. Türeci, Alexey V. Ustinov +1
Long-lived fluxon excitations can be trapped inside a superinductor ring, which is divided into an array of loops by a periodic sequence of Josephson junctions in the quantum regim…
Stochastic Wave-Function Simulation of Irreversible Emission Processes for Open Quantum Systems in a Non-Markovian Environment
Evgeny A. Polyakov, Alexey N. Rubtsov
When conducting the numerical simulation of quantum transport, the main obstacle is a rapid growth of the dimension of entangled Hilbert subspace. The Quantum Monte Carlo simulatio…
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-…
Many-body localization in the Fock space of natural orbitals
Wouter Buijsman, Vladimir Gritsev, Vadim Cheianov
We study the eigenstates of a paradigmatic model of many-body localization in the Fock basis constructed out of the natural orbitals. By numerically studying the participation rati…
