Remotely Controlled Entanglement Generation [PDF]
Quantum, 2023 We consider a system of multiple qubits without any quantum control. We show that one can mediate entanglement between different subsystems in a controlled way by adding a (locally) controlled auxiliary system of the same size that couples via an always-on, distant dependent interaction to the system qubits. Solely by changing the internal state of the

Adaptive optimal control of entangled qubits [PDF]
Science Advances, 2022 Developing fast, robust, and accurate methods for optimal control of quantum systems comprising interacting particles is one of the most active areas of current science. Although a valuable repository of algorithms is available for numerical applications in quantum control, the high computational cost is somewhat overlooked.

Qudit Entanglers Using Quantum Optimal Control
PRX Quantum, 2023 We study the generation of two-qudit entangling quantum logic gates using two techniques in quantum optimal control. We take advantage of both continuous, Lie-algebraic control and digital, Lie-group control. In both cases, the key is access to a time-dependent Hamiltonian which can generate an arbitrary unitary matrix in the group SU($d^2$).

Entanglement controlled single-electron transmittivity
New Journal of Physics, 2006 We consider a system consisting of single electrons moving along a 1D wire in the presence of two magnetic impurities. Such system shows strong analogies with a Fabry - Perot interferometer in which the impurities play the role of two mirrors with a quantum degree of freedom: the spin.

Remote Controlled Entanglement
Physics, 2014 Quantum entanglement is not only one of the most puzzling features of quantum mechanics, but it is also a useful resource that can be consumed to realize tasks that would otherwise be impossible. Famous examples are quantum teleportation and quantum cryptography, which are most useful when entanglement is shared between remote parties.

Entanglement generation in spatially separated systems using quantum walk [PDF]
, 2012 We present a novel scheme to generate entanglement between two spatially separated systems. The scheme makes use of spatial entanglement generated by a single-particle quantum walk which is used to entangle two spatially separated, not necessarily ...

Optimal Dynamical Control of Many-Body Entanglement [PDF]
Physical Review Letters, 2010 The preparation of highly entangled many-body systems is one of the central challenges of both basic and applied science. The complexity of interparticle interaction and environment coupling increases rapidly with the number of to-be-entangled subsystems, rendering the requirements on the control of many-body quantum systems ever more restrictive.
