Quantum interference and manipulation of entanglement in silicon wire waveguide quantum circuits [PDF]

, 2012
Integrated quantum photonic waveguide circuits are a promising approach to realizing future photonic quantum technologies. Here, we present an integrated photonic quantum technology platform utilizing the silicon-on-insulator material system, where ...

Quantum interference in superposed lattices. [PDF]

Proc 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 ...

Ruling out Higher-Order Interference from Purity Principles

Entropy, 2017
As first noted by Rafael Sorkin, there is a limit to quantum interference. The interference pattern formed in a multi-slit experiment is a function of the interference patterns formed between pairs of slits; there are no genuinely new features resulting ...

The musical Mach-Zehnder interferometer [PDF]

Muzikologija, 2018
The phenomenon of interference lies at the heart of quantum physics, and is responsible for many of the unusual aspects of quantum behaviour that deviate from our everyday expectations. Though classical physics allows for waves (e.g.

Generalised phase kick-back: the structure of computational algorithms from physical principles

New Journal of Physics, 2016
The advent of quantum computing has challenged classical conceptions of which problems are efficiently solvable in our physical world. This motivates the general study of how physical principles bound computational power.

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

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 ...
