Quantum Interference between Fundamentally Different Processes Is Enabled by Shaped Input Wavefunctions [PDF]

open access: yesAdvanced Science, 2023
This work presents a general framework for quantum interference between processes that can involve different fundamental particles or quasi‐particles. This framework shows that shaping input wavefunctions is a versatile and powerful tool for producing ...

Quantum Interference of Force [PDF]

open access: yesQuantum, 2018
We show that a quantum particle subjected to a positive force in one path of a Mach-Zehnder interferometer and a null force in the other path may receive a negative average momentum transfer when it leaves the interferometer by a particular exit. In this

Detection of Quantum Interference without an Interference Pattern [PDF]

open access: yesPhysical Review Letters, 2020
Quantum interference is typically detected through the dependence of the interference signal on certain parameters (path length, Aharonov-Bohm flux, etc.), which can be varied in a controlled manner. The destruction of interference by a which-path measurement is a paradigmatic manifestation of quantum effects.

Quantum Interference in Graphene Nanoconstrictions [PDF]

open access: yesNano Letters, 2016
We report quantum interference effects in the electrical conductance of chemical vapor deposited graphene nanoconstrictions fabricated using feedback controlled electroburning. The observed multimode Fabry-Perot interferences can be attributed to reflections at potential steps inside the channel.

Graphene quantum interference photodetector [PDF]

open access: yesBeilstein Journal of Nanotechnology, 2015
In this work, a graphene quantum interference (QI) photodetector was simulated in two regimes of operation. The structure consists of a graphene nanoribbon, Mach–Zehnder interferometer (MZI), which exhibits a strongly resonant transmission of electrons ...

Observation and manipulation of quantum interference in a superconducting Kerr parametric oscillator [PDF]

open access: yesNature Communications
Quantum tunneling is the phenomenon that makes superconducting circuits “quantum”. Recently, there has been a renewed interest in using quantum tunneling in phase space of a Kerr parametric oscillator as a resource for quantum information processing ...

‘Quantum Cheshire Cat’ as simple quantum interference

open access: yesNew Journal of Physics, 2015
In a recent work, Aharonov et al suggested that a photon could be separated from its polarization in an experiment involving pre- and post-selection (Aharonov et al 2013 New J. Phys.

Signature of quantum interference effect in inter-layer Coulomb drag in graphene-based electronic double-layer systems [PDF]

open access: yesNature Communications, 2023
Previous demonstrations of quantum interference in solids have mainly been limited to intra-layer transport within single conductors. Zhu et al. report a new type of inter-layer quantum interference in graphene-based double-layer devices, due to ...

Quantum interference in superposed lattices. [PDF]

open access: yesProc Natl Acad Sci U S A
Charge transport in solids at low temperature reveals a material’s mesoscopic properties and structure. Under a magnetic field, Shubnikov–de Haas (SdH) oscillations inform complex quantum transport phenomena that are not limited by the ground state characteristics and have facilitated extensive explorations of quantum and ...
