Deterministic quantum mechanics: The role of the Maxwell–Boltzmann distribution [PDF]

open access: yes, 2021
To be accepted by the community, the claim that nuclear motion has to be treated classically must be tested for all kinds of phenomena. For the moment we claim that in a quantum chemical calculation, a classical description of nuclear motion is superior ...

Magnetically induced Schrödinger cat states: The shadow of a quantum space [PDF]

open access: yesPhysical Review A, 2023
Schr\"odinger cat states, which are superpositions of macroscopically distinct states, are potentially critical resources for upcoming quantum information technologies.

Analog Quantum Control of Magnonic Cat States on a Chip by a Superconducting Qubit. [PDF]

open access: yesPhysical Review Letters, 2022
We propose to directly and quantum-coherently couple a superconducting transmon qubit to magnons-the quanta of the collective spin excitations, in a nearby magnetic particle.

Is Schrödinger's Cat Alive?

open access: yesQuanta, 2017
Erwin Schrödinger is famous for presenting his wave equation of motion that jump-started quantum mechanics. His disenchantment with the Copenhagen interpretation of quantum mechanics led him to unveil the Schrödinger's cat paradox, which did not get ...

Quantum error correction using squeezed Schrödinger cat states [PDF]

open access: yesPhysical Review A, 2022
Bosonic quantum codes redundantly encode quantum information in the states of a quantum harmonic oscillator, making it possible to detect and correct errors.

Remote Generation of Magnon Schrödinger Cat State via Magnon-Photon Entanglement. [PDF]

open access: yesPhysical Review Letters, 2021
The magnon cat state represents a macroscopic quantum superposition of collective magnetic excitations of large number spins that not only provides fundamental tests of macroscopic quantum effects but also finds applications in quantum metrology and ...

Crossing The Line [PDF]

open access: yes, 2020
Crossing The Line brought together 3 of Europe’s leading theatre companies who make professional touring theatre with learning disabled artists. This chapter investigates their 27 month collaboration, which incorporated residency exchanges, the making of

Algorithm of quantum engineering of large-amplitude high-fidelity Schrödinger cat states [PDF]

open access: yesScientific Reports, 2022
We present an algorithm of quantum engineering of large-amplitude $$\ge 5$$ ≥ 5 high-fidelity $$\ge 0.99$$ ≥ 0.99 even/odd Schrödinger cat states (SCSs) using a single mode squeezed vacuum (SMSV) state as resource.

Schrödinger's Cat: Where Does The Entanglement Come From?

open access: yesQuanta, 2017
Schrödinger's cat is one of the most striking paradoxes of quantum mechanics that reveals the counterintuitive aspects of the microscopic world. Here, I discuss the paradox in the framework of quantum information.
