A Quantum Key Distribution Routing Scheme for a Zero-Trust QKD Network System: A Moving Target Defense Approach

open access: yesBig Data and Cognitive Computing
Quantum key distribution (QKD), a key application of quantum information technology and “one-time pad” (OTP) encryption, enables secure key exchange with information-theoretic security, meaning its security is grounded in the laws of physics rather than ...

Spectroscopy on two coupled flux qubits

open access: yes, 2003
We have performed spectroscopy measurements on two coupled flux qubits. The qubits are coupled inductively, which results in a $\sigma_1^z\sigma_2^z$ interaction.

Cosmic muon flux attenuation methods for superconducting qubit experiments

open access: yesNew Journal of Physics
We propose and demonstrate two practical mitigation methods to attenuate the cosmic muon flux, compatible with experiments involving superconducting qubits: shallow underground sites and device orientation. Using a specifically-built cosmic muon detector,

Majorana Superconducting Qubit

open access: yesPhysical Review Letters, 2018
We propose a platform for universal quantum computation that uses conventional $s$-wave superconducting leads to address a topological qubit stored in spatially separated Majorana bound states in a multi-terminal topological superconductor island.

Scalable quantum computing with Josephson charge qubits

open access: yes, 2003
A goal of quantum information technology is to control the quantum state of a system, including its preparation, manipulation, and measurement. However, scalability to many qubits and controlled connectivity between any selected qubits are two of the ...

Basic quantum circuits for classification and approximation tasks

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2020
We discuss a quantum circuit construction designed for classification. The circuit is built of regularly placed elementary quantum gates, which implies the simplicity of the presented solution. The realization of the classification task is possible after

Interqubit coupling mediated by a high-excitation-energy quantum object

open access: yes, 2008
We consider a system composed of two qubits and a high-excitation-energy quantum object used to mediate coupling between the qubits. We treat the entire system quantum mechanically and analyze the properties of the eigenvalues and eigenstates of the ...
