Coherent-state optical qudit cluster state generation and teleportation via homodyne detection
Jaewan Kim, Juhui Lee, Se-Wan Ji +3
Defining a computational basis of pseudo-number states, we interpret a coherent state of large amplitude, , as a qudit --- a -level quantum system --- in a s…
A realist interpretation of quantum mechanics based on undecidability due to gravity
Rodolfo Gambini, Luis Pedro Garcia-Pintos, Jorge Pullin
We summarize several recent developments suggesting that solving the problem of time in quantum gravity leads to a solution of the measurement problem in quantum mechanics. This ap…
Entanglement-assisted quantum turbo codes
Mark M. Wilde, Min-Hsiu Hsieh, Zunaira Babar
An unexpected breakdown in the existing theory of quantum serial turbo coding is that a quantum convolutional encoder cannot simultaneously be recursive and non-catastrophic. These…
Undecidability as solution to the problem of measurement: fundamental criterion for the production of events
Rodolfo Gambini, Luis Pedro Garcia-Pintos, Jorge Pullin
In recent papers we put forth a new interpretation of quantum mechanics, colloquially known as ``the Montevideo interpretation''. This interpretation is based on taking into accoun…
Disentanglement and Decoherence without dissipation at non-zero temperatures
G. W. Ford, R. F. O'Connell
Decoherence is well understood, in contrast to disentanglement. According to common lore, irreversible coupling to a dissipative environment is the mechanism for loss of entangleme…
Generalized X states of N qubits and their symmetries
Sai Vinjanampathy, A. R. P. Rau
Several families of states such as Werner states, Bell-diagonal states and Dicke states are useful to understand multipartite entanglement. Here we present a [2^(N+1)-1]-parameter…
Exact analysis of disentanglement for continuous variable systems and application to a two-body system at zero temperature in an arbitrary heat bath
G. W. Ford, R. F. O'Connell
We outline an exact approach to decoherence and entanglement problems for continuous variable systems. The method is based on a construction of quantum distribution functions intro…
Entanglement without Dissipation: A Touchstone for an exact Comparison of Entanglement Measures
G. W. Ford, Yang Gao, R. F. O'Connell
Entanglement, which is an essential characteristic of quantum mechanics, is the key element in potential practical quantum information and quantum communication systems. However, t…
A progressive diagonalization scheme for the Rabi Hamiltonian
Feng Pan, Xin Guan, Yin Wang +1
A diagonalization scheme for the Rabi Hamiltonian, which describes a qubit interacting with a single-mode radiation field via a dipole interaction, is proposed. It is shown that th…
Quantum discord for two-qubit X-states
Mazhar Ali, A. R. P. Rau, Gernot Alber
Quantum discord, a kind of quantum correlation, is defined as the difference between quantum mutual information and classical correlation in a bipartite system. In general, this co…
An axiomatic formulation of the Montevideo interpretation of quantum mechanics
Rodolfo Gambini, Luis Pedro Garcia-Pintos, Jorge Pullin
We make a first attempt to axiomatically formulate the Montevideo interpretation of quantum mechanics. In this interpretation environmental decoherence is supplemented with loss of…
An Invisible Quantum Tripwire
Petr M. Anisimov, Daniel J. Lum, S. Blane McCracken +2
We present here a quantum tripwire, which is a quantum optical interrogation technique capable of detecting an intrusion with very low probability of the tripwire being revealed to…
Enhancing image contrast using coherent states and photon number resolving detectors
Aaron Pearlman, Alexander Ling, Elizabeth Goldschmidt +2
We experimentally map the transverse profile of diffraction-limited beams using photon-number-resolving detectors. We observe strong compression of diffracted beam profiles for hig…
