Josephson-phase qubit without tunneling
M. H. S. Amin, A. Yu. Smirnov, Alec Maassen van den Brink
We show that a complete set of one-bit gates can be realized by coupling the two logical states of a phase qubit to a third level (at higher energy) using microwave pulses. Thus, o…
Hamiltonian and Linear-Space Structure for Damped Oscillators: II. Critical Points
S. C. Chee, Alec Maassen van den Brink, K. Young
The eigenvector expansion developed in the preceding paper for a system of damped linear oscillators is extended to critical points, where eigenvectors merge and the time-evolution…
Hamiltonian and Linear-Space Structure for Damped Oscillators: I. General Theory
S. C. Chee, Alec Maassen van den Brink, K. Young
The phase space of damped linear oscillators is endowed with a bilinear map under which the evolution operator is symmetric. This analog of self-adjointness allows properties f…
Comment on `Aharonov--Casher-Effect Suppression of Macroscopic Tunneling of Magnetic Flux'
Alec Maassen van den Brink
A recent Letter [1] has proposed a device, consisting of an rf SQUID with the junction replaced by a double one, i.e. a Bloch transistor. For symmetric Josephson couplings, and for…
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…
