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 ...

Graphene quantum interference photodetector [PDF]
Beilstein 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 ...

Generalized Multiphoton Quantum Interference [PDF]
Physical Review X, 2015 Nonclassical interference of photons lies at the heart of optical quantum information processing. Here, we exploit tunable distinguishability to reveal the full spectrum of multiphoton nonclassical interference.

‘Quantum Cheshire Cat’ as simple quantum interference
New 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.

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

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 ...

Quantum interference in superposed lattices. [PDF]
Proc Natl Acad Sci U S ACharge 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 topological ...

Interference as an information-theoretic game [PDF]
Quantum, 2021 The double slit experiment provides a clear demarcation between classical and quantum theory, while multi-slit experiments demarcate quantum and higher-order interference theories. In this work we show that these experiments pertain to a broader class of

Engineering quantum interference [PDF]
Applied Physics Letters, 2018 A model for describing the interference and diffraction of wave functions of one-dimensional Josephson array interferometers is presented. The derived expression for critical current modulations accounts for an arbitrary number of square junctions, the variable distance between these, and the variable size of their area.
