Authors: Alexander N. Poddubny, Klemens Winkler, Benjamin A. Stickler, Uroš Delić, Markus Aspelmeyer, Anton V. Zasedatelev,
Abstract summary: We present a protocol that maximizes entanglement generation between two masses interacting directly through $1/rn$ potential. The protocol combines optimal quantum control of continuously measured masses with their non-equilibrium dynamics, driven by a time-dependent interaction strength.

Abstract: We present a protocol that maximizes unconditional entanglement generation between two masses interacting directly through $1/r^{n}$ potential. The protocol combines optimal quantum control of continuously measured masses with their non-equilibrium dynamics, driven by a time-dependent interaction strength. Applied to a pair of optically trapped sub-micron particles coupled via electrostatic interaction, our protocol enables unconditional entanglement generation at the fundamental limit of the conditional state and with an order of magnitude smaller interaction between the masses compared to the existing steady-state approaches.

Steady-state entanglement of interacting masses in free space through optimal feedback control [0.0]
We employ linear quadratic Gaussian (LQG) control to engineer the phase space dynamics of the two masses. We propose Einstein-Podolsky-Rosen (EPR)-type variance minimisation constraints for the feedback to facilitate unconditional entanglement generation.

Qubit Analog with Polariton Superfluid in an Annular Trap [0.0]
We report on the experimental realization and characterization of a qubit analog with semiconductor exciton-polaritons. In our system, a condensate of exciton-polaritonsfluid is confined by a spatially-patterned pump laser in an annular trap. We observe coherent oscillations between a pair of counter-circulating superfluid vortex states of the polaritons coupled by elastic scattering off the laser-imprinted potential.

Optimal control for state preparation in two-qubit open quantum systems driven by coherent and incoherent controls via GRAPE approach [77.34726150561087]
We consider a model of two qubits driven by coherent and incoherent time-dependent controls. The dynamics of the system is governed by a Gorini-Kossakowski-Sudarshan-Lindblad master equation. We study evolution of the von Neumann entropy, purity, and one-qubit reduced density matrices under optimized controls.

Quantum vibrational mode in a cavity confining a massless spinor field [91.3755431537592]
We analyse the reaction of a massless (1+1)-dimensional spinor field to the harmonic motion of one cavity wall. We demonstrate that the system is able to convert bosons into fermion pairs at the lowest perturbative order.

Tuning long-range fermion-mediated interactions in cold-atom quantum simulators [68.8204255655161]
Engineering long-range interactions in cold-atom quantum simulators can lead to exotic quantum many-body behavior. Here, we propose several tuning knobs, accessible in current experimental platforms, that allow to further control the range and shape of the mediated interactions.

Dynamics of a multipartite hybrid quantum system with beamsplitter, dipole-dipole, and Ising interactions [0.0]
We make use of one such hybrid bipartite quantum model, with one subsystem made of a pair of qubits and another comprising a pair of oscillators. Our basic model is the standard double Jaynes-Cummings system, which is known to support both entanglement transfer and entanglement sudden death. We show that compared to the beamsplitter or dipole-dipole interaction, the Ising interaction can have a significant positive impact on entanglement sudden death and birth.

flip-flop qubit is encoded in the states with antiparallel donor-bound electron and donor nuclear spins in silicon. We study the multilevel system that is formed by the interacting electron and nuclear spins. We propose an optimal control scheme that produces fast and robust single-qubit gates in the presence of low-frequency noise.
