Robust Adaptive Quantum Phase Estimation
Shibdas Roy, Ian R. Petersen, Elanor H. Huntington
Quantum parameter estimation is central to many fields such as quantum computation, communications and metrology. Optimal estimation theory has been instrumental in achieving the b…
Reaching Quantum Consensus with Directed Links: Missing Symmetry and Switching Interactions
Guodong Shi, Shuangshuang Fu, Ian R. Petersen
In this paper, we study consensus seeking of quantum networks under directed interactions defined by a set of permutation operators among a network of qubits. The state evolution o…
A Direct Coupling Coherent Quantum Observer for a Single Qubit Finite Level Quantum System
Ian R. Petersen
This paper considers the problem of constructing a direct coupling quantum observer for a single qubit finite level quantum system plant. The proposed observer is a single mode lin…
Preparation of Pure Gaussian States via Cascaded Quantum Systems
Shan Ma, Matthew J. Woolley, Ian R. Petersen +1
This paper provides an alternative approach to the problem of preparing pure Gaussian states in a linear quantum system. It is shown that any pure Gaussian state can be generated b…
A Direct Coupling Coherent Quantum Observer
Ian R. Petersen
This paper considers the problem of constructing a direct coupling quantum observer for a closed linear quantum system. The proposed observer is shown to be able to estimate some b…
Robust manipulation of superconducting qubits in the presence of fluctuations
Daoyi Dong, Chunlin Chen, Bo Qi +2
Superconducting quantum systems are promising candidates for quantum information processing due to their scalability and design flexibility. However, the existence of defects, fluc…
