Impacts of Decoder Latency on Utility-Scale Quantum Computer Architectures
Abdullah Khalid, Allyson Silva, Gebremedhin A. Dagnew +10 more·Nov 13, 2025
The speed of a fault-tolerant quantum computer is dictated by the reaction time of its classical electronics, that is, the total time required by decoders and controllers to determine the outcome of a logical measurement and execute subsequent condit...
Crossing Symmetry and Entanglement
Navin McGinnis·Nov 13, 2025
We study the interplay between crossing symmetry and entanglement in $2 \to 2$ scattering within local quantum field theories that possess an $SU(N)$ global symmetry. In particular, we recast scattering amplitudes of fixed helicity as quantum operati...
Quantum Computational Structure of $SU(N)$ Scattering
Navin McGinnis·Nov 13, 2025
We study scattering of particles which obey an $SU(N)$ global symmetry through the lens of quantum computation and quantum algorithms. We show that for scattering between particles which transform in the fundamental or anti-fundamental representation...
Enhanced shortcuts to adiabaticity for coherent atom transport in a family of two-dimensional dynamical optical lattices
Sascha H. Hauck, Vladimir M. Stojanovic·Nov 13, 2025
In view of the compelling need for coherent atom transport as a prerequisite for a variety of emerging quantum technologies, we investigate such transport on the example of an adjustable family of two-dimensional optical lattices [L. Tarruell {\em et...
Assessing Finite Scalability in Early Fault-Tolerant Quantum Computing for Homogeneous Catalysts
Yanbing Zhou, Athena Caesura, Corneliu Buda +3 more·Nov 13, 2025
As quantum hardware advances toward fault-tolerant operation, an intermediate stage known as early fault-tolerant quantum computing (EFTQC) is emerging, where partial error correction enables meaningful computation. In this regime, the ability of qua...
Lévy-Khintchine Structure Enables Fast-Forwardable Lindbladian Simulation
Minbo Gao, Zhengfeng Ji, Chenghua Liu·Nov 13, 2025
Simulation of open quantum systems is an area of active research in quantum algorithms. In this work, we revisit the connection between Markovian open-system dynamics and averages of Hamiltonian real-time evolutions, which we refer to as Hamiltonian ...

We present QuCoWE a framework that learns quantumnative word embeddings by training shallow hardwareefficient parameterized quantum circuits PQCs with a contrastive skipgram objective Words are encoded by datareuploading circuits with controlled ring...
General quantum backflow in realistic wave packets
Tomasz Paterek, Arseni Goussev·Nov 13, 2025
Quantum backflow is a counterintuitive phenomenon in which the probability density of a quantum particle propagates opposite to its momentum. Experimental observation of backflow has remained elusive due to two main challenges: (i) the effect is intr...
First and second quantized digital quantum simulations of bosonic systems
Mathias Mikkelsen, Hubert Okadome Valencia·Nov 13, 2025
We compare the basic resource requirements for first and second quantized bosonic mappings in a system consisting of $N$ particles in $M$ modes. In addition to the standard binary first quantized mapping, we investigate the unary first quantized mapp...
