The Quantum Car
Robert Malaney
I explore the use of quantum information as a security enabler for the future driverless vehicle. Specifically, I investigate the role combined classical and quantum information ca…
Linear quantum systems with diagonal passive Hamiltonian and a single dissipative channel
Shan Ma, Ian R. Petersen, Matthew J. Woolley
Given any covariance matrix corresponding to a so-called pure Gaussian state, a linear quantum system can be designed to achieve the assigned covariance matrix. In most cases, howe…
Entanglement Generation via Non-Gaussian Transfer over Atmospheric Fading Channels
Nedasadat Hosseinidehaj, Robert Malaney
In this work we probe the usefulness of non-Gaussian entangled states as a resource for quantum communication through atmospheric channels. We outline the initial conditions in whi…
The Transfer Function of Generic Linear Quantum Stochastic Systems Has a Pure Cascade Realization
H. I. Nurdin, S. Grivopoulos, I. R. Petersen
This paper establishes that generic linear quantum stochastic systems have a pure cascade realization of their transfer function, generalizing an earlier result established only fo…
The impact of nuclear spin dynamics on electron transport through donors
Samuel K. Gorman, Matthew A. Broome, William J. Baker +1
We present an analysis of electron transport through two weakly coupled precision placed phosphorus donors in silicon. In particular, we examine the (1,1) to (0,2) charge transitio…
A Possible Implementation of a Direct Coupling Coherent Quantum Observer
Ian R. Petersen, Elanor H. Huntington
This paper considers the problem of implementing a previously proposed direct coupling quantum observer for a closed linear quantum system. This observer is shown to be able to est…
Optimal quantum algorithm for polynomial interpolation
Andrew M. Childs, Wim van Dam, Shih-Han Hung +1
We consider the number of quantum queries required to determine the coefficients of a degree-d polynomial over GF(q). A lower bound shown independently by Kane and Kutin and by Mey…
Local optimality of a coherent feedback scheme for distributed entanglement generation: the idealized infinite bandwidth limit
Zhan Shi, Hendra I. Nurdin
The purpose of this paper is to prove a local optimality property of a recently proposed coherent feedback configuration for distributed generation of EPR entanglement using two no…
Fault Tolerant Filtering and Fault Detection for Quantum Systems Driven By Fields in Single Photon States
Qing Gao, Daoyi Dong, Ian R. Petersen +1
The purpose of this paper is to solve a fault tolerant filtering and fault detection problem for a class of open quantum systems driven by a continuous-mode bosonic input field in…
Fast machine-learning online optimization of ultra-cold-atom experiments
P. B. Wigley, P. J. Everitt, A. van den Hengel +12
Machine-designed control of complex devices or experiments can discover strategies superior to those developed via simplified models. We describe an online optimization algorithm b…
Entanglement in a linear coherent feedback chain of nondegenerate optical parametric amplifiers
Zhan Shi, Hendra I. Nurdin
This paper is concerned with linear quantum networks of nondegenerate optical parametric amplifiers (NOPAs), with up to 6, which are interconnected in a coherent feedback c…
Si nuclear spins as a resource for donor spin qubits in silicon
Gary Wolfowicz, Pierre-Andre Mortemousque, Roland Guichard +4
Nuclear spin registers in the vicinity of electron spins in solid state systems offer a powerful resource to address the challenge of scalability in quantum architectures. We inves…
Enhancing quantum transport in a photonic network using controllable decoherence
Devon N. Biggerstaff, René Heilmann, Aidan A. Zecevik +7
Transport phenomena on a quantum scale appear in a variety of systems, ranging from photosynthetic complexes to engineered quantum devices. It has been predicted that the efficienc…
On the Optimality of Square Root Measurements in Quantum State Discrimination
Nicola Dalla Pozza, Gianfranco Pierobon
Distinguishing assigned quantum states with assigned probabilities via quantum measurements is a crucial problem for the transmission of classical information through quantum chann…
Utilizing weak pump depletion to stabilize squeezed vacuum states
Timo Denker, Dirk Schütte, Maximilian H. Wimmer +3
We propose and demonstrate a pump-phase locking technique that makes use of weak pump depletion (WPD) - an unavoidable effect that is usually neglected - in a sub-threshold optical…
Non-exponential Fidelity Decay in Randomized Benchmarking with Low-Frequency Noise
M. A. Fogarty, M. Veldhorst, R. Harper +4
We show that non-exponential fidelity decays in randomized benchmarking experiments on quantum dot qubits are consistent with numerical simulations that incorporate low-frequency n…
Coherently tracking the covariance matrix of an open quantum system
Zibo Miao, Michael R. Hush, Matthew James
Coherent feedback control of quantum systems has demonstrable advantages over measurement-based control, but so far there has been little work done on coherent estimators and more…
Optimization of distributed EPR entanglement generated between two Gaussian fields by the modified steepest descent method
Zhan Shi, Hendra I. Nurdin
Recent theoretical investigations on quantum coherent feedback networks have found that with the same pump power, the Einstein-Podolski-Rosen (EPR)-like entanglement generated via…
