Loop Quantum Photonic Chip for Coherent Multi‐Time‐Step Evolution

Laser &Photonics Reviews, EarlyView.
A loop quantum photonic chip (Loop‐QPC) enabling efficient multi‐step quantum simulation in a single run is demonstrated. Combining recirculating loops with cycle‐or‐measure control, Loop‐QPC eliminates repeated reprogramming and reduces loss. Experimental demonstration of three‐step unitary evolution confirms high‐fidelity operation, showcasing the ...

Exchange Gate on the Qudit Space and Fock Space

, 2002
We construct the exchange gate with small elementary gates on the space of qudits, which consist of three controlled shift gates and three "reverse" gates. This is a natural extension of the qubit case.

Antiferromagnetic Chains in a Monolayer of Molecular Qubits Assembled on Graphene

Small, EarlyView.
This work explores the deposition onto graphene of a dithiazole‐based molecular qubit, [Cu(dttt)2], (dttt− = 1,3,2‐dithiazole‐4‐thione‐5‐thiolate), under ultra‐high vacuum conditions. Analytical techniques, including STM, XPS, and X‐ray absorption, reveal the molecular arrangement and magnetic interactions, emphasizing the role of vdW interactions in ...

Shell model and Hartree-Fock calculations of electron scattering form factors for 25Mg nucleus

Iraqi Journal of Physics, 2019
Shell model and Hartree-Fock calculations have been adopted to study the elastic and inelastic electron scattering form factors for 25Mg nucleus. The wave functions for this nucleus have been utilized from the shell model using USDA two-body effective ...

On Stopping Fock-Space Processes [PDF]

Journal of Theoretical Probability, 2018
We consider the theory of stopping bounded processes within the framework of Hudson--Parthasarathy quantum stochastic calculus, for both identity and vacuum adaptedness. This provides significant new insight into Coquio's method of stopping (J. Funct. Anal. 238:149-180, 2006).

Spin Crossover around Room Temperature: Effects of Remote Ligand Symmetry Breaking within Jäger‐Type Iron(II) Complexes

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Remote symmetry breaking in Jäger‐type iron(II) complexes shifts stepwise spin crossover (SCO) profiles to continuous profiles with transition temperatures around room temperature. In a bottom‐up approach, we studied the feedback of slight molecular modifications on the spin crossover (SCO) properties of otherwise structurally conserved iron(II ...

Optimized Fock space in the large N limit of quartic interactions in matrix models

Nuclear Physics B, 2016
We consider the problem of quantization of the bosonic membrane via the large N limit of its matrix regularizations HN in Fock space. We prove that there exists a choice of the Fock space frequency such that HN can be written as a sum of a non ...

Between famine and freedom: Food prices during the Indonesian War of Independence, 1945–9

The Economic History Review, EarlyView.
Abstract This paper investigates how the Indonesian War of Independence (1945‒9) influenced staple food prices, and how fluctuations in those prices, in turn, shaped the trajectory and dynamics of the conflict. We compiled a dataset comprising more than 8600 prices for staple foods covering the entire Indonesian archipelago from 1939‒49, allowing us to

Yang-Mills theory and the $\mathcal{N}=2$ spinning path integral

SciPost Physics
We embed the perturbative Fock state of the Yang-Mills BV-multiplet in the vertex operator algebra of the path-integral for the $\mathcal{N}=2$ supersymmetric world line and evaluate the pull-back of the latter to an integral form on supermoduli space ...

The Newman--Shapiro problem

, 2018
We give a negative answer to the Newman--Shapiro problem on weighted approximation for entire functions formulated in 1966 and motivated by the theory of operators on the Fock space.
