Stationary Phase and the Theory of Measurement -- 1/N expansion --
R. Fukuda
The measuring process is studied, where a macroscopic number N of particles in the detector interact with the object. The macrovariable accompanies the stationary phase in the path…
On the Effect of Quantum Interaction Distance on Quantum Addition Circuits
Byung-Soo Choi, Rodney Van Meter
We investigate the theoretical limits of the effect of the quantum interaction distance on the speed of exact quantum addition circuits. For this study, we exploit graph embedding…
Quantum Repeater with Encoding
Liang Jiang, Jacob M. Taylor, Kae Nemoto +3
We propose a new approach to implement quantum repeaters for long distance quantum communication. Our protocol generates a backbone of encoded Bell pairs and uses the procedure of…
Avoiding entanglement sudden-death via measurement feedback control in a quantum network
Naoki Yamamoto, Hendra I. Nurdin, Matthew R. James +1
In this paper, we consider a linear quantum network composed of two distantly separated cavities that are connected via a one-way optical field. When one of the cavity is damped an…
