Overcoming phonon-induced dephasing for indistinguishable photon sources [PDF]
, 2012 Reliable single photon sources constitute the basis of schemes for quantum communication and measurement based quantum computing. Solid state single photon sources based on quantum dots are convenient and versatile but the electronic transitions that ...

Two-photon interference from a quantum dot microcavity : persistent pure dephasing and suppression of time jitter [PDF]
, 2014 We demonstrate the emission of highly indistinguishable photons from a quasi-resonantly pumped coupled quantum dot-microcavity system operating in the regime of cavity quantum electrodynamics. Changing the sample temperature allows us to vary the quantum

Many-Body Quantum Interference and the Saturation of Out-of-Time-Order Correlators. [PDF]
Physical Review Letters, 2018 Out-of-time-order correlators (OTOCs) have been proposed as sensitive probes for chaos in interacting quantum systems. They exhibit a characteristic classical exponential growth, but saturate beyond the so-called scrambling or Ehrenfest time τ_{E} in the

Advanced Functional Materials, EarlyView.An original method is presented for producing artificial spider silk fibers with magnetic and magnetomechanical responsiveness, which consists in coating them with a nanometer‐thick layer of FeCo alloy by sputtering deposition. The challenge of combining organic materials and inorganic magnetic nanostructures is addressed, thus taking a step forward ...

QKD-Based Quantum Private Query Protocol in the Single-Photon Interference Communication System
IEEE Access, 2019 In this paper, we propose a quantum-key-distribution-based quantum private query protocol (QKD-based QPQ) utilizing the uncertainty relation of the photon path and the interference result in the single-photon interference circuit.

Quantum Interference Controlled Spin-Polarized Electron Transmission in Graphene Nanoribbons
, 2022 In graphene-based nano junctions, the edge-topology of graphene nanoribbons (GNRs) is crucial to modulate the spin-dependent transport through quantum interference (QI). Herein we have investigated the quantum transport properties of armchair GNRs (AGNRs)

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene
Advanced Functional Materials, EarlyView.Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...
