Adaptive Optical Phase Estimation Using Time-Symmetric Quantum Smoothing
T. A. Wheatley, D. W. Berry, H. Yonezawa +7
Quantum parameter estimation has many applications, from gravitational wave detection to quantum key distribution. We present the first experimental demonstration of the time-symme…
Error Correction and Degeneracy in Surface Codes Suffering Loss
T. M. Stace, S. D. Barrett
Many proposals for quantum information processing are subject to detectable loss errors. In this paper, we give a detailed account of recent results in which we showed that topolog…
Experimental feedback control of quantum systems using weak measurements
G. G. Gillett, R. B. Dalton, B. P. Lanyon +7
A goal of the emerging field of quantum control is to develop methods for quantum technologies to function robustly in the presence of noise. Central issues are the fundamental lim…
Intracavity weak nonlinear phase shifts with single photon driving
W. J. Munro, K. Nemoto, G. J. Milburn
We investigate a doubly resonant optical cavity containing a Kerr nonlinear medium that couples two modes by a cross phase modulation. One of these modes is driven by a single phot…
Optimised generation of heralded Fock states using parametric down conversion
Agata M. Branczyk, T. C. Ralph, Wolfram Helwig +1
The generation of heralded pure Fock states via spontaneous parametric down conversion (PDC) relies on perfect photon-number correlations in the output modes. Correlations in any o…
Quantum Transition State Theory for proton transfer reactions in enzymes
Jacques P. Bothma, Joel Gilmore, Ross H. McKenzie
We consider the role of quantum effects in the transfer of hyrogen-like species in enzyme-catalysed reactions. This study is stimulated by claims that the observed magnitude and te…
Efficient measurement of quantum dynamics via compressive sensing
A. Shabani, R. L. Kosut, M. Mohseni +5
The resources required to characterise the dynamics of engineered quantum systems-such as quantum computers and quantum sensors-grow exponentially with system size. Here we adapt t…
Matchgate quantum computing and non-local process analysis
S. Ramelow, A. Fedrizzi, A. M. Steinberg +1
In the circuit model, quantum computers rely on the availability of a universal quantum gate set. A particularly intriguing example is a set of two-qubit only gates: matchgates, al…
Vibration-enhanced quantum transport
F. L. Semião, K. Furuya, G. J. Milburn
In this paper, we study the role of collective vibrational motion in the phenomenon of electronic energy transfer (EET) along a chain of coupled electronic dipoles with varying exc…
Mixed state discrimination using optimal control
B. L. Higgins, B. M. Booth, A. C. Doherty +3
We present theory and experiment for the task of discriminating two nonorthogonal states, given multiple copies. We implement several local measurement schemes, on both pure states…
Cooling and control of a cavity opto-electromechanical system
Kwan H. Lee, Terry G. McRae, Glen I. Harris +2
We implement a cavity opto-electromechanical system integrating electrical actuation capabilities of nanoelectromechanical devices with ultrasensitive mechanical transduction achie…
Fault Tolerance in Parity-State Linear Optical Quantum Computing
A. J. F. Hayes, H. L. Haselgrove, Alexei Gilchrist +1
We use a combination of analytical and numerical techniques to calculate the noise threshold and resource requirements for a linear optical quantum computing scheme based on parity…
Quantum limited particle sensing in optical tweezers
Jian Wei Tay, Magnus T. L. Hsu, Warwick P. Bowen
Particle sensing in optical tweezers systems provides information on the position, velocity and force of the specimen particles. The conventional quadrant detection scheme is appli…
Noiseless Linear Amplification and Distillation of Entanglement
G. Y. Xiang, T. C. Ralph, A. P. Lund +2
The idea of signal amplification is ubiquitous in the control of physical systems, and the ultimate performance limit of amplifiers is set by quantum physics. Increasing the amplit…
Violation of the Leggett-Garg inequality with weak measurements of photons
M. E. Goggin, M. P. Almeida, M. Barbieri +4
By weakly measuring the polarization of a photon between two strong polarization measurements, we experimentally investigate the correlation between the appearance of anomalous val…
Demonstrating mesoscopic superpositions in double-well Bose-Einstein condensates
T. J. Haigh, A. J. Ferris, M. K. Olsen
The availability of Bose-Einstein condensates as mesoscopic or macroscopic quantum objects has aroused new interest in the possiblity of making and detecting coherent superposition…
Experimental criteria for steering and the Einstein-Podolsky-Rosen paradox
E. G. Cavalcanti, S. J. Jones, H. M. Wiseman +1
We formally link the concept of steering (a concept created by Schrodinger but only recently formalised by Wiseman, Jones and Doherty [Phys. Rev. Lett. 98, 140402 (2007)] and the c…
Parametric self pulsing in a quantum opto-mechanical system
C A Holmes, G J Milburn
We describe an opto-mechanical system in which the coupling between optical and mechanical degrees of freedom takes the form of a fully quantised third-order parametric interaction…
Asymmetric Gaussian steering: when Alice and Bob disagree
S. L. W. Midgley, A. J. Ferris, M. K. Olsen
Asymmetric steering is an effect whereby an inseparable bipartite system can be found to be described by either quantum mechanics or local hidden variable theories depending on whi…
