Control of entanglement and the high-entanglement limit

Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2003
We examine two-particle entanglement and ways in which it might be coherently controlled. Control is desirable for successful implementation of quantum computing. As one result, we find that reaching very high entanglement may be feasible experimentally.

Quantum Phase Control of Entanglement

Physical Review Letters, 2004
A method of phase control of entanglement in two-qubit systems is proposed. We show that by changing a relative phase of the pulses that drive the transitions in a two-qubit system with closed-loop couplings, one can control entanglement at will. The method relies on adiabatic dynamics via time-delayed pulse sequences and can be implemented with both ...

Control of Attosecond Entanglement and Coherence

Physical Review Letters, 2021
Calculations are presented of vibrational wave packet dynamics in H_{2}^{+} ions formed by ionization of neutral H_{2} by a pair of attosecond extreme ultraviolet laser pulses, using time-delayed dissociation of the cation by an ultraviolet probe pulse.

Entanglement purification via controlled–controlled-NOT operations

Physics Letters A, 2000
Abstract We present an entanglement purification protocol based on controlled–controlled-NOT operations and Bell state measurements. We show that the protocol is more efficient than the standard protocol of Bennett et al. [Phys. Rev. Lett. 76 (1996) 722].
