Quantum Bayesian approach to circuit QED measurement
Alexander N. Korotkov
We present a simple formalism describing evolution of a qubit in the process of its measurement in a circuit QED setup. When a phase-sensitive amplifier is used, the evolution depe…
Implementing the Quantum von Neumann Architecture with Superconducting Circuits
Matteo Mariantoni, H. Wang, T. Yamamoto +14
The von Neumann architecture for a classical computer comprises a central processing unit and a memory holding instructions and data. We demonstrate a quantum central processing un…
Resonator/zero-Qubit architecture for superconducting qubits
Andrei Galiautdinov, Alexander N. Korotkov, John M. Martinis
We analyze the performance of the Resonator/zero-Qubit (RezQu) architecture in which the qubits are complemented with memory resonators and coupled via a resonator bus. Separating…
Flying microwave qubits with nearly perfect transfer efficiency
Alexander N. Korotkov
We propose a procedure for transferring the state a microwave qubit via a transmission line from one resonator to another resonator, with a theoretical efficiency arbitrarily close…
