One-spin quantum logic gates from exchange interactions and a global magnetic field
Lian-Ao Wu, Daniel A. Lidar, Mark Friesen
It has been widely assumed that one-qubit gates in spin-based quantum computers suffer from severe technical difficulties. We show that one-qubit gates can in fact be generated usi…
Pseudo-Digital Qubits: A General Approach
Mark Friesen, Robert Joynt, M. A. Eriksson
Pseudo-digital coupling has recently been proposed as a simple but robust technique for reducing gating errors in quantum dot quantum computers. Here, we discuss the technique in t…
Dynamic scaling theory of the Kosterlitz-Thouless-Berezinskii transition: ubiquitous finite size effects
Louis Colonna-Romano, Stephen W. Pierson, Mark Friesen
A numerical study of the neutral two-dimensional (2D) lattice Coulomb gas is performed to examine dynamic scaling, finite size effects, and the dynamic critical exponent of the…
Dynamic Scaling at the Zero-field 2D Superconducting Transition
S. M. Ammirata, Mark Friesen, Stephen W. Pierson +4
Zero-field current-voltage (I-V) characteristics of a thin ("two-dimensional") crystal are reported and analyzed in two ways. The "conventional" approach yi…
