Generation of Scalable Genuine Multipartite Gaussian Entanglement with a Parametric Amplifier Network
Saesun Kim, Sho Onoe, Alberto M. Marino
Genuine multipartite entanglement is a valuable resource in quantum information science, as it exhibits stronger non-locality compared to bipartite entanglement. This non-locality…
Direct measurement of the Husimi-Q function of the electric-field in the time-domain
Sho Onoe, Stéphane Virally, Denis V. Seletskiy
We develop the theoretical tools necessary to promote electro-optic sampling to a time-domain quantum tomography technique. Our proposed framework implements detection of the time…
Telefilters, telemirrors, and causality
Joshua Foo, Sho Onoe, Magdalena Zych +1
We present new theoretical models for quantum optical mode-selective filters and mirrors using continuous-variable teleportation. We call these devices telefilters and telemirrors…
Realizing an Unruh-DeWitt detector through electro-optic sampling of the electromagnetic vacuum
Sho Onoe, Thiago L. M. Guedes, Andrey S. Moskalenko +3
A new theoretical framework to describe the experimental advances in electro-optic detection of broadband quantum states, specifically the quantum vacuum, is devised. By making use…
Multipartite Gaussian Entanglement of Formation
Sho Onoe, Spyros Tserkis, Austin P. Lund +1
Entanglement of formation is a fundamental measure that quantifies the entanglement of bipartite quantum states. This measure has recently been extended into multipartite states ta…
Thermality, causality and the quantum-controlled Unruh-deWitt detector
Joshua Foo, Sho Onoe, Robert B. Mann +1
Particle detector models such as the Unruh-deWitt detector are widely used in relativistic quantum information and field theory to probe the global features of spacetime and quantu…
Generating multi-partite entanglement from the quantum vacuum with a finite-lifetime mirror
Joshua Foo, Sho Onoe, Magdalena Zych +1
Observers following special classes of finite-lifetime trajectories have been shown to experience an effective temperature, a generalisation of the Unruh temperature for uniformly…
Unruh-deWitt detectors in quantum superpositions of trajectories
Joshua Foo, Sho Onoe, Magdalena Zych
Unruh-deWitt detectors have been utilised widely as probes for quantum particles, entanglement and spacetime curvature. Here, we extend the standard treatment of an Unruh-deWitt de…
Switchable bipartite and genuine tripartite entanglement via an optoelectromechanical interface
Cheng Jiang, Spyros Tserkis, Kevin Collins +3
Controllable multipartite entanglement is a crucial element in quantum information processing. Here we present a scheme that generates switchable bipartite and genuine tripartite e…
Quantifying entanglement of formation for two-mode Gaussian states: Analytical expressions for upper and lower bounds and numerical estimation of its exact value
Spyros Tserkis, Sho Onoe, Timothy C. Ralph
Entanglement of formation quantifies the entanglement of a state in terms of the entropy of entanglement of the least entangled pure state needed to prepare it. An analytical expre…
Universal Transformation of Displacement Operators and its Application to Homodyne Tomography In Differing Relativistic Reference Frames
Sho Onoe, Timothy. C. Ralph
In this paper, we study how a displacement of a quantum system appears under a change of relativistic reference frame. We introduce a generic method in which a displacement operato…
Particle production and apparent decoherence due to an accelerated time-delay
Sho Onoe, Daiqin Su, Timothy Ralph
We study the radiation produced by an accelerated time-delay acting on the left moving modes. Through analysis via the Schrodinger picture, we find that the final state is a two-mo…
