Quantum Zeno dynamics of qubits in a squeezed reservoir: effect of measurement selectivity
Md. Manirul Ali, Po-Wen Chen, Alec Maassen van den Brink +1
A complete suppression of the exponential decay in a qubit (interacting with a squeezed vacuum reservoir) can be achieved by frequent measurements of adequately chosen observables.…
A characterization of global entanglement
Peter J. Love, Alec Maassen van den Brink, A. Yu. Smirnov +5
We define a set of entanglement monotones for qubits and give a single measure of entanglement in terms of these. This measure is zero except on globally entangled…
Book review of Z. Haba, Feynman Integral and Random Dynamics in Quantum Physics
Alec Maassen van den Brink
The book deals with a stochastic formulation of path integration in real time, by rotating the_space_ variables over exp(i pi/4). Preliminary chapters deal with quantum and classic…
Comments on `Stable Quantum Computation of Unstable Classical Chaos,' `Efficient Quantum Computing Insensitive to Phase Errors,' and `Quantum Computer Inverting Time Arrow for Macroscopic Systems'
Alec Maassen van den Brink
Recently, the paper B. Georgeot and D.L. Shepelyansky, Phys. Rev. Lett._86_, 5393 (2001) has been criticized [C. Zalka, quant-ph/0110019; L. Di'osi, quant-ph/0110026]. The Letter c…
Liouville invariance in quantum and classical mechanics
Alec Maassen van den Brink, A. M. Zagoskin
The density-matrix and Heisenberg formulations of quantum mechanics follow--for unitary evolution--directy from the Schr"odinger equation. Nevertheless, the symmetries of the corre…
