Strengthened Bell inequalities for entanglement verification (2009)
Lougovski, Pavel, Van Enk, S. J.
Bell inequalities were meant to test quantum mechanics vs local hidden variable models, but can also be used to verify entanglement. For entanglement verification purposes one assumes the validity of...
Characterizing Entanglement Sources (2009)
Lougovski, Pavel, Van Enk, S. J.
We discuss how to characterize entanglement sources with finite sets of measurements. The measurements do not have to be tomographically complete, and may consist of POVMs rather than von Neumann...

Verifying multipartite mode entanglement of W states (2009)
Lougovski, Pavel, Van Enk, S. J., Choi, Kyung Soo, Papp, Scott B., Deng, Hui, Kimble, H. J.
We construct a method for verifying mode entanglement of N-mode W states. The ideal W state contains exactly one excitation symmetrically shared between N modes, but our method takes the existence of...
Characterization of multipartite entanglement for one photon shared among four optical modes (2009)
Papp, Scott B., Choi, Kyung Soo, Deng, Hui, Lougovski, Pavel, Van Enk, S. J., Kimble, H. J.
Access to genuine multipartite entanglement of quantum states enables advances in quantum information science and also contributes to the understanding of strongly correlated quantum systems. We...

Detecting and Quantifying Entanglement via Bayesian Updating (2008)
Lougovski, Pavel, Van Enk, S. J.
We show how a straightforward Bayesian updating procedure allows one to detect and quantify entanglement from any finite set of measurement results. The measurements do not have to be tomographically...
Jacobs, Kurt, Lougovski, Pavel, Blencowe, Miles
We show that it is possible to perform a continuous measurement that continually projects a nano-resonator into its energy eigenstates by employing a linear coupling with a two-state system. This...
Emergent Quantum Jumps in a Nano-Electro-Mechanical System (2006)
Jacobs, Kurt, Lougovski, Pavel
We describe a nano-electromechnical system that exhibits the "retroactive" quantum jumps discovered by Mabuchi and Wiseman [Phys. Rev. Lett. 81, 4620 (1998)]. This system consists of a Cooper-pair...

Quantum Computing, Metrology, and Imaging (2005)
Lee, Hwang, Lougovski, Pavel, Dowling, Jonathan P.
Information science is entering into a new era in which certain subtleties of quantum mechanics enables large enhancements in computational efficiency and communication security. Naturally, precise...

One-atom maser: Non-separable atom pairs (2002)
Englert, Berthold-Georg, Lougovski, Pavel, Solano, Enrique, Walther, Herbert
When a one-atom maser is operated in the standard way -- excited, resonant two-level atoms traverse the resonator at random times -- the emerging atoms are entangled with the cavity field. As a...
