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…
Parity effect in superconducting aluminum single electron transistors with spatial gap profile controlled by film thickness
T. Yamamoto, Y. Nakamura, Yu. A. Pashkin +2
We propose a novel method for suppression of quasiparticle poisoning in Al Coulomb blockade devices. The method is based on creation of a proper energy gap profile along the device…
Single-shot measurement of the Josephson charge qubit
O. Astafiev, Yu. A. Pashkin, T. Yamamoto +2
We demonstrate single-shot readout of quantum states of the Josephson charge qubit. The quantum bits are transformed into and stored as classical bits (charge quanta) in a dynamic…
Quantum oscillations in two coupled charge qubits
Yu. A. Pashkin, T. Yamamoto, O. Astafiev +3
Despite an apparent progress in implementing individual solid-state qubits, there have been no experimental reports so far on multi-bit gates required for building a real quantum c…
Charge echo in a Cooper-pair box
Y. Nakamura, Yu. A. Pashkin, T. Yamamoto +1
A spin-echo-type technique is applied to an artificial two-level system that utilizes charge degree of freedom in a small superconducting electrode. Gate-voltage pulses are used to…
