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

Observation and manipulation of quantum interference in a superconducting Kerr parametric oscillator [PDF]
Nature Communications, 2023 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 ...

Detection of Quantum Interference without an Interference Pattern [PDF]
Physical 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]
Nano 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.

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