Reexamination of decoherence in quantum walks on the hypercube
Frederick W. Strauch
The effect of decoherence on the continuous-time quantum walk on the hypercube is revisited. Previously, an exact solution was found for a decoherence model that preserved the effe…
Quantum behavior of the dc SQUID phase qubit
Kaushik Mitra, F. W. Strauch, C. J. Lobb +3
We analyze the behavior of a dc Superconducting Quantum Interference Device (SQUID) phase qubit in which one junction acts as a phase qubit and the rest of the device provides isol…
Tunneling phase gate for neutral atoms in a double-well lattice
Frederick W. Strauch, Mark Edwards, Eite Tiesinga +2
We propose a new two--qubit phase gate for ultra--cold atoms confined in an experimentally realized tilted double--well optical lattice [Sebby--Strabley et al., Phys. Rev. A {\bf 7…
Theoretical analysis of perfect quantum state transfer with superconducting qubits
Frederick W. Strauch, Carl J. Williams
Superconducting quantum circuits, fabricated with multiple layers, are proposed to implement perfect quantum state transfer between nodes of a hypercube network. For tunable device…
Any-order propagation of the nonlinear Schroedinger equation
Frederick W. Strauch
We derive an exact propagation scheme for nonlinear Schroedinger equations. This scheme is entirely analogous to the propagation of linear Schroedinger equations. We accomplish thi…
Connecting the discrete and continuous-time quantum walks
Frederick W. Strauch
Recently, quantized versions of random walks have been explored as effective elements for quantum algorithms. In the simplest case of one dimension, the theory has remained divided…
