Gravity is not a Pairwise Local Classical Channel
Natacha Altamirano, Paulina Corona-Ugalde, Robert B. Mann +1
It is currently believed that there is no experimental evidence on possibly quantum features of gravity or gravity-motivated modifications of quantum mechanics. Here we show that s…
Detecting gravitational decoherence with clocks: Limits on temporal resolution from a classical channel model of gravity
Kiran Khosla, Natacha Altamirano
The notion of time is given a different footing in Quantum Mechanics and General Relativity, treated as a parameter in the former and being an observer dependent property in the la…
Symmetric and antisymmetric forms of the Pauli master equation (for interaction of matter and antimatter quantum states)
A. Y. Klimenko
When applied to matter and antimatter states, the Pauli master equation (PME) may have two forms: time-symmetric, which is conventional, and time-antisymmetric, which is suggested…
Quantum Repeaters Using Continuous Variable Teleportation
Josephine Dias, Timothy C Ralph
Quantum optical states are fragile and can become corrupted when passed through a lossy communication channel. Unlike for classical signals, optical amplifiers cannot be used to re…
Active demultiplexing of single-photons from a solid-state source
F. Lenzini, B. Haylock, J. C. Loredo +11
A scheme for active temporal-to-spatial demultiplexing of single-photons generated by a solid-state source is introduced. The scheme scales quasi-polynomially with photon number, p…
Quantum Estimation of Parameters of Classical Spacetimes
T. G. Downes, J. R. van Meter, E. Knill +2
We describe a quantum limit to measurement of classical spacetimes. Specifically, we formulate a quantum Cramer-Rao lower bound for estimating the single parameter in any one-param…
Quantum Fisher Information as a Predictor of Decoherence in the Preparation of Spin-Cat States for Quantum Metrology
Samuel P. Nolan, Simon A. Haine
In its simplest form, decoherence occurs when a quantum state is entangled with a second state, but the results of measurements made on the second state are not accessible. As the…
The SLH framework for modeling quantum input-output networks
Joshua Combes, Joseph Kerckhoff, Mohan Sarovar
Many emerging quantum technologies demand precise engineering and control over networks consisting of quantum mechanical degrees of freedom connected by propagating electromagnetic…
Pseudo steady-state non-Gaussian EPR-steering of massive particles in pumped and damped Bose-Hubbard dimers
M. K. Olsen
We propose and analyse a pumped Bose-Hubbard dimer as a source of continuous-variable Einstein-Podolsky-Rosen (EPR) steering with non-Gaussian statistics. We use the truncated Wign…
Surpassing the no-cloning limit with a heralded hybrid linear amplifier for coherent states
Jing Yan Haw, Jie Zhao, Josephine Dias +6
The no-cloning theorem states that an unknown quantum state cannot be cloned exactly and deterministically due to the linearity of quantum mechanics. Associated with this theorem i…
Finite size effects and equilibration in Bose-Hubbard chains with central well dephasing
F. Martinet, M. K. Olsen
We investigate Bose-Hubbard chains in a central depleted well configuration, with dephasing in the middle well. We look at equilibration of populations, pseudo-entropy, and entangl…
Ultrafine Entanglement Witnessing
Farid Shahandeh, Martin Ringbauer, Juan C. Loredo +1
Entanglement witnesses are invaluable for efficient quantum entanglement certification without the need for expensive quantum state tomography. Yet, standard entanglement witnessin…
Pumped-up SU(1,1) interferometry
Stuart S. Szigeti, Robert J. Lewis-Swan, Simon A. Haine
Although SU(1,1) interferometry achieves Heisenberg-limited sensitivities, it suffers from one major drawback: only those particles outcoupled from the pump mode contribute to the…
Exact solution of the two-axis countertwisting Hamiltonian for the half-integer case
Feng Pan, Yao-Zhong Zhang, Jerry P. Draayer
Bethe ansatz solutions of the two-axis countertwisting Hamiltonian for any (integer and half-integer) are derived based on the Jordan-Schwinger (differential) boson realization…
Measurement-Device-Independent Approach to Entanglement Measures
Farid Shahandeh, Michael J. W. Hall, Timothy C. Ralph
Within the context of semiquantum nonlocal games, the trust can be removed from the measurement devices in an entanglement-detection procedure. Here we show that a similar approach…
Exact solution of the two-axis countertwisting Hamiltonian
Feng Pan, Yao-Zhong Zhang, Jerry P. Draayer
It is shown that the two-axis countertwisting Hamiltonian is exactly solvable when the quantum number of the total angular momentum of the system is an integer after the Jordan-Sch…
Coherence protection in coupled quantum systems
Helen Cammack, Peter Kirton, Paul Eastham +2
The interaction of a quantum system with its environment causes decoherence, setting a fundamental limit on the suitability of a system for quantum information processing. However,…
Experimental test of photonic entanglement in accelerated reference frames
Matthias Fink, Ana Rodriguez-Aramendia, Johannes Handsteiner +7
The quantization of the electromagnetic field has successfully paved the way for the development of the Standard Model of Particle Physics and has established the basis for quantum…
Hidden -algebraic structure in Rabi model and its 2-photon and two-mode generalizations
Yao-Zhong Zhang
It is shown that the (driven) quantum Rabi model and its 2-photon and 2-mode generalizations possess a hidden -algebraic structure which explains the origin of the quasi-exa…
Keldysh meets Lindblad: Correlated Gain and Loss in Higher-Order Perturbation Theory
Clemens Müller, Thomas M. Stace
Motivated by correlated decay processes producing gain, loss and lasing in driven semiconductor quantum-dots, we develop a theoretical technique using Keldysh diagrammatic perturba…
Multipartite Causal Correlations: Polytopes and Inequalities
Alastair A. Abbott, Christina Giarmatzi, Fabio Costa +1
We consider the most general correlations that can be obtained by a group of parties whose causal relations are well-defined, although possibly probabilistic and dependent on past…
A solid-state single-photon filter
L. de Santis, C. Antón, B. Reznychenko +10
A strong limitation of linear optical quantum computing is the probabilistic operation of two-quantum bit gates based on the coalescence of indistinguishable photons. A route to de…
Arbitrary Multi-Qubit Generation
Farid Shahandeh, Austin P. Lund, Timothy C. Ralph +1
We propose and analyse a scheme for single-rail-encoded arbitrary multi-qubit quantum-state generation to provide a versatile tool for quantum optics and quantum information applic…
General relativistic effects in quantum interference of "clocks"
Magdalena Zych, Igor Pikovski, Fabio Costa +1
Quantum mechanics and general relativity have been each successfully tested in numerous experiments. However, the regime where both theories are jointly required to explain physica…
