Entanglement generated between a single atom and a laser pulse
Andrew Silberfarb, Ivan H. Deutsch
We quantify the entanglement generated between an atom and a laser pulse in free space. We find that the entanglement calculated using a simple closed-system Jaynes-Cummings Hamilt…
Teleportation in a non-inertial frame
Paul M. Alsing, David McMahon, G. J. Milburn
In this work, we describe the process of teleportation between Alice in an inertial frame, and Rob who is in uniform acceleration with respect to Alice. The fidelity of the telepor…
Quantum Key Distribution Using Equiangular Spherical Codes
Joseph M. Renes
Mutually unbiased bases have been extensively studied in the literature and are simple and effective in quantum key distribution protocols, but they are not optimal. Here equiangul…
Symmetric Informationally Complete Quantum Measurements
Joseph M. Renes, Robin Blume-Kohout, A. J. Scott +1
We consider the existence in arbitrary finite dimensions d of a POVM comprised of d^2 rank-one operators all of whose operator inner products are equal. Such a set is called a ``sy…
Multipartite entanglement, quantum-error-correcting codes, and entangling power of quantum evolutions
A. J. Scott
We investigate the average bipartite entanglement, over all possible divisions of a multipartite system, as a useful measure of multipartite entanglement. We expose a connection be…
The transition to classical chaos in a coupled quantum system through continuous measurement
Shohini Ghose, Paul Alsing, Ivan Deutsch +3
Continuous observation of a quantum system yields a measurement record that faithfully reproduces the classically predicted trajectory provided that the measurement is sufficiently…
Completely positive maps with memory
Sonja Daffer, Krzysztof Wodkiewicz, James D. Cresser +1
The prevailing description for dissipative quantum dynamics is given by the Lindblad form of a Markovian master equation, used under the assumption that memory effects are negligib…
Tutorial Notes on One-Party and Two-Party Gaussian States
Berthold-Georg Englert, Krzysztof Wódkiewicz
Gaussian states -- or, more generally, Gaussian operators -- play an important role in Quantum Optics and Quantum Information Science, both in discussions about conceptual issues a…
Information transfer through a one-atom micromaser
Animesh Datta, Biplab Ghosh, A. S. Majumdar +1
We consider a realistic model for the one-atom micromaser consisting of a cavity maintained in a steady state by the streaming of two-level Rydberg atoms passing one at a time thro…
Gleason-Type Derivations of the Quantum Probability Rule for Generalized Measurements
Carlton M. Caves, Christopher A. Fuchs, Kiran Manne +1
We prove a Gleason-type theorem for the quantum probability rule using frame functions defined on positive-operator-valued measures (POVMs), as opposed to the restricted class of o…
Entanglement Sharing in the Two-Atom Tavis-Cummings Model
T. E. Tessier, I. H. Deutsch, A. Delgado +1
Individual members of an ensemble of identical systems coupled to a common probe can become entangled with one another, even when they do not interact directly. We investigate how…
Entangling power of the quantum baker's map
A. J. Scott, Carlton M. Caves
We investigate entanglement production in a class of quantum baker's maps. The dynamics of these maps is constructed using strings of qubits, providing a natural tensor-product str…
Physical-resource demands for scalable quantum computation
Carlton M. Caves, Ivan H. Deutsch, Robin Blume-Kohout
The primary resource for quantum computation is Hilbert-space dimension. Whereas Hilbert space itself is an abstract construction, the number of dimensions available to a system is…
Quantum State Control via Trap-induced Shape Resonance in Ultracold Atomic Collisions
R. Stock, E. L. Bolda, I. H. Deutsch
We investigate controlled collisions between trapped but separated ultracold atoms. The interaction between atoms is treated self-consistently using an energy-dependent delta-funct…
Optimal conclusive teleportation of quantum states
L. Roa, A. Delgado, I. Fuentes-Guridi
Quantum teleportation of qudits is revisited. In particular, we analyze the case where the quantum channel corresponds to a non-maximally entangled state and show that the success…
Teleportation with a uniformly accelerated partner
Paul M. Alsing, G. J. Milburn
In this work, we give a description of the process of teleportation between Alice in an inertial frame, and Rob who is in uniform acceleration with respect to Alice. The fidelity o…
Nonlocality of Two-Mode Squeezing with Internal Noise
Sonja Daffer, Krzysztof Wodkiewicz, John K. McIver
We examine the quantum states produced through parametric amplification with internal quantum noise. The internal diffusion arises by coupling both modes of light to a reservoir fo…
