Understanding the Role of Hydrogen and Oxygen in Electronic Phase Changes of Nickelates

open access: yesAdvanced Functional Materials, EarlyView.
The reversible exchange of hydrogen and oxygen in solids is key to their electronic and electro‐chemical functionality. A combination of methods is employed to study the interaction of hydrogen with a prototypical quantum material in a non‐destructive and time‐dependent manner.

Universal Quantum Algorithm [PDF]

open access: yesarXiv, 2016
Quantum amplitude amplification and quantum phase estimation are two fundamental quantum algorithms. All known quantum algorithms are derived from these two algorithms. Even the adiabatic quantum algorithms can also be efficiently simulated using quantum phase estimation.

2D Covalent Moiré Superlattice from Fluorinating Twisted Bilayer Graphene

open access: yesAdvanced Functional Materials, EarlyView.
A novel class of moiré materials, termed covalent moiré superlattice is proposed, which can be synthesized by functionalizing moiré van der Waals materials. By fluorinating twisted bilayer graphene, the weak van der Waals interactions between twisted graphene layers are transformed into strong covalent bonds, making the moiré superlattice effects ...

Highly efficient frequency conversion with bandwidth compression of quantum light

open access: yesNature Communications, 2017
In quantum information technology the output of one element often does not match the required frequency and bandwidth of the input of the next element. Here, Allgaieret al.

Impenetrable Barriers and Canonical Quantization [PDF]

open access: yesarXiv, 2001
We address a conceptual issue of reconciling the traditional canonical quantization framework of quantum theory with the spatially restricted quantum dynamics and the related spectral problems for confined and global observables of the quantum system.
