A Bootstrapping Approach for Generating Maximally Path-Entangled Photon States
Kishore T Kapale, Jonathan P Dowling
We propose a bootstrapping approach to generation of maximally path-entangled states of photons, so called ``NOON states''. Strong atom-light interaction of cavity QED can be emplo…
General linear-optical quantum state generation scheme: Applications to maximally path-entangled states
N. M. VanMeter, P. Lougovski, D. B. Uskov +3
We introduce schemes for linear-optical quantum state generation. A quantum state generator is a device that prepares a desired quantum state using product inputs from photon sourc…
Strong Violations of Bell-type Inequalities for Path-Entangled Number States
Christoph F. Wildfeuer, Austin P. Lund, Jonathan P. Dowling
We show that nonlocal correlation experiments on the two spatially separated modes of a maximally path-entangled number state may be performed and lead to a violation of a Clauser-…
Alternate Scheme for Optical Cluster-State Generation without Number-Resolving Photon Detectors
Mark M. Wilde, Federico Spedalieri, Jonathan P. Dowling +1
We design a controlled-phase gate for linear optical quantum computing by using photodetectors that cannot resolve photon number. An intrinsic error-correction circuit corrects err…
Does the Third Law of Thermodynamics hold in the Quantum Regime?
R. F. O'Connell
The first in a long series of papers by John T. Lewis, G. W. Ford and the present author, considered the problem of the most general coupling of a quantum particle to a linear pass…
Quantum States of Light Produced by a High-Gain Optical Parametric Amplifier for Use in Quantum Lithography
Girish S. Agarwal, Kam Wai Chan, Robert W. Boyd +2
We present a theoretical analysis of the properties of an unseeded optical parametic amplifier (OPA) used as the source of entangled photons for applications in quantum lithography…
Relational physics with real rods and clocks and the measurement problem of quantum mechanics
Rodolfo Gambini, Jorge Pullin
The use of real clocks and measuring rods in quantum mechanics implies a natural loss of unitarity in the description of the theory. We briefly review this point and then discuss t…
Efimov states and their Fano resonances in a neutron-rich nucleus
I. Mazumdar, A. R. P. Rau, V. S. Bhasin
Asymmetric resonances in elastic n+C scattering are attributed to Efimov states of such neutron-rich nuclei, that is, three-body bound states of the n+n+C system when…
Continous Measurement of the Energy Eigenstates of a Nanomechanical Resonator without a Non-Demolition Probe
Kurt Jacobs, Pavel Lougovski, Miles Blencowe
We show that it is possible to perform a continuous measurement that continually projects a nano-resonator into its energy eigenstates by employing a linear coupling with a two-sta…
Local and Global Distinguishability in Quantum Interferometry
Gabriel A. Durkin, Jonathan P. Dowling
A statistical distinguishability based on relative entropy characterises the fitness of quantum states for phase estimation. This criterion is employed in the context of a Mach-Zeh…
Concatenated beam splitters, optical feed-forward and the nonlinear sign gate
Kurt Jacobs, Jonathan P. Dowling
We consider a nonlinear sign gate implemented using a sequence of two beam splitters, and consider the use of further sequences of beam splitters to implement feed-forward so as to…
Emergent Quantum Jumps in a Nano-Electro-Mechanical System
Kurt Jacobs, Pavel Lougovski
We describe a nano-electromechnical system that exhibits the "retroactive" quantum jumps discovered by Mabuchi and Wiseman [Phys. Rev. Lett. 81, 4620 (1998)]. This system consists…
Quantum Information and Entropy
Subhash Kak
Thermodynamic entropy is not an entirely satisfactory measure of information of a quantum state. This entropy for an unknown pure state is zero, although repeated measurements on c…
M-body Pure State Entanglement
Feng Pan, J. P. Draayer
The simple entanglement of N-body N-particle pure states is extended to the more general M-body or M-body N-particle states where . Some new features of the M-body N-parti…
Anomalous diffusion in quantum Brownian motion with colored noise
G. W. Ford, R. F. O'Connell
Anomalous diffusion is discussed in the context of quantum Brownian motion with colored noise. It is shown that earlier results follow simply and directly from the fluctuation-diss…
A quantum violation of the second law?
G. W. Ford, R. F. O'Connell
An apparent violation of the second law of thermodynamics occurs when an atom coupled to a zero-temperature bath, being necessarily in an excited state, is used to extract work fro…
Feedback control for communication with non-orthogonal states
Kurt Jacobs
Communicating classical information with a quantum system involves the receiver making a measurement on the system so as to distinguish as well as possible the alphabet of states u…
Entropy of a Quantum Oscillator coupled to a Heat Bath and implications for Quantum Thermodynamics
G. W. Ford, R. F. O'Connell
The free energy of a quantum oscillator in an arbitrary heat bath at a temperature T is given by a "remarkable formula" which involves only a single integral. This leads to a corre…
