Feedback enhanced entanglement in a spin-1/2 XY dimer model permeated by a transverse magnetic field
AIP Advances, 2018 This paper studies the ability of feedback control to reduce the effect of decoherence and enhance entanglement in an interacting spin-1/2 XY dimer model in the presence of a transverse magnetic field.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Bone tumours present significant challenges for affected patients, as multimodal therapy often leads to prolonged physical limitations. This is particularly critical during childhood and adolescence, as it can negatively impact physiological development and psychosocial resilience.

Two-photon entanglement in multi-qubit bi-directional waveguide QED
, 2016 We study entanglement generation and control in bi-directional waveguide QED driven by a two photon Gaussian wavepacket. In particular, we focus on how increasing the number of qubits affects the overall average pairwise entanglement in the system.

Coherent control of multipartite entanglement
Physical Review A, 2015 Quantum entanglement between an arbitrary number of remote qubits is examined analytically. We show that there is a non-probabilistic way to address in one context the management of entanglement of an arbitrary number of mixed-state qubits by engaging quantitative measures of entanglement and a specific external control mechanism.

Quantum Control and Entanglement in a Chemical Compass [PDF]
Physical Review Letters, 2010 The radical pair mechanism is one of the two main hypotheses to explain the navigability of animals in weak magnetic fields, enabling e.g. birds to see the Earth's magnetic field. It also plays an essential role in the field of spin chemistry. Here, we show how quantum control can be used to either enhance or reduce the performance of such a chemical ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Entanglement enhances cooling in microscopic quantum fridges
, 2014 Small self-contained quantum thermal machines function without external source of work or control, but using only incoherent interactions with thermal baths. Here we investigate the role of entanglement in a small self-contained quantum refrigerator.

Universal feedback control of two-qubit entanglement [PDF]
, 2017 We consider two-qubit undergoing local dissipation and subject to local driving. We then determine the optimal Markovian feedback action to preserve initial entanglement as well as to create stationary entanglement with the help of an XY interaction ...

Influence of Stark Shift on Entanglement of Two Qubits in the Two-Photon Tavis-Cummings Model
EPJ Web of Conferences, 2015 Considering two-atom degenerate two-photon Tavis-Cummings model, we investigate the entanglement between two atoms prepared initially in the coherent disentangled states and cavity field prepared in few-photon Fock state, and study the effect of the ...
