Deriving Grover's lower bound from simple physical principles [PDF]
New Journal of Physics, 2016 Grover's algorithm constitutes the optimal quantum solution to the search problem and provides a quadratic speed-up over all possible classical search algorithms.

Ruling out Higher-Order Interference from Purity Principles [PDF]
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 ...

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 ...

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

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.

Interference of Quantum Channels [PDF]
Physical Review Letters, 2003 We show how interferometry can be used to characterise certain aspects of general quantum processes, in particular, the coherence of completely positive maps.

Quantum interference in plasmonic circuits [PDF]
Nature Nanotechnology, 2013 Surface plasmon polaritons (plasmons) are a combination of light and a collective oscillation of the free electron plasma at metal-dielectric interfaces. This interaction allows sub-wavelength confinement of light, beyond the diffraction limit inherent to dielectric structures.

‘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.
