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…
Spin Correlations as a Probe of Quantum Synchronization in Trapped Ion Phonon-Lasers
Michael R. Hush, Weibin Li, Sam Genway +2
We investigate quantum synchronization theoretically in a system consisting of two cold ions in microtraps. The ions' motion is damped by a standing-wave laser whilst also being dr…
Quantum Key Distribution over Combined Atmospheric Fading Channels
Nedasadat Hosseinidehaj, Robert Malaney
In this work we analyze a quantum communication scheme for entanglement-based continuous variable quantum key distribution between two ground stations. Communication occurs via a s…
Effect of phase shifts on EPR entanglement generated on two propagating Gaussian fields via coherent feedback
Zhan Shi, Hendra I. Nurdin
Recent work has shown that deploying two nondegenerate optical parametric amplifiers (NOPAs) separately at two distant parties in a coherent feedback loop generates stronger Einste…
Gaussian Entanglement Distribution via Satellite
Nedasadat Hosseinidehaj, Robert Malaney
In this work we analyse three quantum communication schemes for the generation of Gaussian entanglement between two ground stations. Communication occurs via a satellite over two i…
Modular Quantum Memories Using Passive Linear Optics and Coherent Feedback
Hendra I. Nurdin, John E. Gough
In this paper, we show that quantum memory for qudit states encoded in a single photon pulsed optical field has a conceptually simple modular realization using only passive linear…
Experimental realization of a dynamic squeezing gate
Kazunori Miyata, Hisashi Ogawa, Petr Marek +4
Squeezing is a nonlinear Gaussian operation that is the key component in construction of other nonlinear Gaussian gates. In our implementation of the squeezing gate, the amount and…
Quantum filtering for multiple input multiple output systems driven by arbitrary zero-mean jointly Gaussian input fields
Hendra I. Nurdin
In this paper, we treat the quantum filtering problem for multiple input multiple output (MIMO) Markovian open quantum systems coupled to multiple boson fields in an arbitrary zero…
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…
On the Quasi-Balanceable Class of Linear Quantum Stochastic Systems
Onvaree Techakesari, Hendra I. Nurdin
This paper concerns the recently proposed quasi-balanced truncation model reduction method for linear quantum stochastic systems. It has previously been shown that the quasi-balanc…
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…
Analytical study of bound states in graphene nano-ribbons and carbon nanotubes: The variable phase method and the relativistic Levinson theorem
D. S. Miserev
The problem of localized states in 1D systems with the relativistic spectrum, namely, graphene stripes and carbon nanotubes, has been analytically studied. The bound state as a sup…
Comparing resolved-sideband cooling and measurement-based feedback cooling on an equal footing: analytical results in the regime of ground-state cooling
Kurt Jacobs, Hendra I. Nurdin, Frederick W. Strauch +1
We show that in the regime of ground-state cooling, simple expressions can be derived for the performance of resolved-sideband cooling --- an example of coherent feedback control -…

John E. Gough, Matthew R. James, Hendra I. Nurdin
We introduce a new class of continuous matrix product (CMP) states and establish the stochastic master equations (quantum filters) for an arbitrary quantum system probed by a boson…
Two-mode squeezed states in cavity optomechanics via engineering of a single reservoir
M. J. Woolley, A. A. Clerk
We study theoretically a three-mode optomechanical system where two mechanical oscillators are independently coupled to a single cavity mode. By optimized two-tone or four-tone dri…

The preparation stage of optical qubits is an essential task in all the experimental setups employed for the test and demonstration of Quantum Optics principles. We consider a dete…
Design of coherent quantum observers for linear quantum systems
Shanon L. Vuglar, Hadis Amini
Quantum versions of control problems are often more difficult than their classical counterparts because of the additional constraints imposed by quantum dynamics. For example, the…
