Replicating the benefits of closed timelike curves without breaking causality
Xiao Yuan, Syed M. Assad, Jayne Thompson +6
In general relativity, closed timelike curves can break causality with remarkable and unsettling consequences. At the classical level, they induce causal paradoxes disturbing enoug…
Experimental Superposition of Orders of Quantum Gates
Lorenzo M. Procopio, Amir Moqanaki, Mateus Araújo +7
In a quantum computer, creating superpositions of quantum bits (qubits) in different states can lead to a speed-up over classical computers [1], but quantum mechanics also allows f…
Analog of the Clauser-Horne-Shimony-Holt inequality for steering
Eric G. Cavalcanti, Christopher J. Foster, Maria Fuwa +1
The Clauser-Horne-Shimony-Holt (CHSH) inequality (and its permutations), are necessary and sufficient criteria for Bell nonlocality in the simplest Bell-nonlocality scenario: 2 par…
Precise wavefunction engineering with magnetic resonance
P. B. Wigley, L. M. Starkey, S. S. Szigeti +4
Controlling quantum fluids at their fundamental length scale will yield superlative quantum simulators, precision sensors, and spintronic devices. This scale is typically below the…
Qubit-Programmable Operations on Quantum Light Fields
Marco Barbieri, Nicolò Spagnolo, Franck Ferreyrol +3
Engineering quantum operations is one of the main abilities we need for developing quantum technologies and designing new fundamental tests. Here we propose a scheme for realising…
Asymmetric steering in coherent transport of atomic population with a three-well Bose-Hubbard model
M. K. Olsen
We analyse the Einstein-Podolsky-Rosen (EPR) steering properties in a three-well Bose-Hubbard model under the mechanism of coherent transport of atomic population (CTAP). This proc…
Theoretical Analysis of an Ideal Noiseless Linear Amplifier for Einstein-Podolsky-Rosen Entanglement Distillation
J. Bernu, S. Armstrong, T. Symul +2
We study the operational regime of a noiseless linear amplifier based on quantum scissors that can nondeterministically amplify the one photon component of a quantum state with wea…
Heisenberg-limited metrology with information recycling
Simon A. Haine, Stuart S. Szigeti, Matthias D. Lang +1
Information recycling has been shown to improve the sensitivity of atom interferometers by exploiting atom-light entanglement. In this paper, we apply information recycling to an i…
Fast convergence of imaginary time evolution tensor network algorithms by recycling the environment
Ho N. Phien, Ian P. McCulloch, Guifré Vidal
We propose an environment recycling scheme to speed up a class of tensor network algorithms that produce an approximation to the ground state of a local Hamiltonian by simulating a…
Proposal for a motional-state Bell inequality test with ultracold atoms
R. J. Lewis-Swan, K. V. Kheruntsyan
We propose and theoretically simulate an experiment for demonstrating a motional-state Bell inequality violation for pairs of momentum-entangled atoms produced in Bose-Einstein con…
Rapid readout of a register of qubits using open loop quantum control
Joshua Combes, Aaron Denney, Howard M. Wiseman
Measurements are a primitive for characterizing quantum systems. Reducing the time taken to perform a measurement may be beneficial in many areas of quantum information processing.…
Characterizing quantum dynamics with initial system-environment correlations
Martin Ringbauer, Christopher J. Wood, Kavan Modi +3
We fully characterize the reduced dynamics of an open quantum system initially correlated with its environment. Using a photonic qubit coupled to a simulated environment we tomogra…
Precision Measurements Using Squeezed Spin States via Two-axis Counter-twisting Interactions
Emi Yukawa, Gerard Milburn, Masahito Ueda +1
We show that the two-axis counter twisting interaction squeezes a coherent spin state into three states of interest in quantum information, namely, the twin-Fock state, the equally…
Weak-value amplification: state of play
George C. Knee, Joshua Combes, Christopher Ferrie +1
Weak values arise in quantum theory when the result of a weak measurement is conditioned on a subsequent strong measurement. The majority of the trials are discarded, leaving only…
General description of quasi-adiabatic dynamical phenomena near exceptional points
Thomas J. Milburn, Jörg Doppler, Catherine A. Holmes +3
The appearance of so-called exceptional points in the complex spectra of non-Hermitian systems is often associated with phenomena that contradict our physical intuition. One exampl…
Measurement-Based Noiseless Linear Amplification for Quantum Communication
Helen M. Chrzanowski, Nathan Walk, Syed M. Assad +5
Entanglement distillation is an indispensable ingredient in extended quantum communication networks. Distillation protocols are necessarily non-deterministic and require advanced e…
Quantum Key Distribution without sending a Quantum Signal
T. C. Ralph, N. Walk
Quantum Key Distribution is a quantum communication technique in which random numbers are encoded on quantum systems, usually photons, and sent from one party, Alice, to another, B…
Quantum metrology and its application in biology
Michael A. Taylor, Warwick P. Bowen
Quantum metrology provides a route to overcome practical limits in sensing devices. It holds particular relevance to biology, where sensitivity and resolution constraints restrict…
Quantum estimation of the Schwarzschild space-time parameters of the Earth
David Edward Bruschi, Animesh Datta, Rupert Ursin +2
We propose a quantum experiment to measure with high precision the Schwarzschild space-time parameters of the Earth. The scheme can also be applied to measure distances by taking i…
