Spectral statistics, non-equilibrium dynamics and thermalization in random matrices with global $\mathbb{Z}_2$-symmetry
Adway Kumar Das·Jun 19, 2025
$\mathbb{Z}_2$ symmetry is ubiquitous in quantum mechanics where it drives various phase transitions and emergent physics. The role of $\mathbb{Z}_2$ symmetry in the thermalization of a local observable in a disordered system can be understood using ...
Observation of Criticality-Enhanced Quantum Sensing in Nonunitary Quantum Walks
Lei Xiao, Saubhik Sarkar, Kunkun Wang +2 more·Jun 19, 2025

Hemanth Kannamarlapudi, Sowmya Chintalapudi·Jun 19, 2025
Navigation is a very crucial aspect of autonomous vehicle ecosystem which heavily relies on collecting and processing large amounts of data in various states and taking a confident and safe decision to define the next vehicle maneuver. In this paper,...
Mixed-Signal Quantum Circuit Design for Option Pricing Using Design Compiler
Yu-Ting Kao, Yeong-Jar Chang, Ying-Wei Tseng·Jun 19, 2025
Prior studies have largely focused on quantum algorithms, often reducing parallel computing designs to abstract models or overly simplified circuits. This has contributed to the misconception that most applications are feasible only through VLSI circ...

We combine classical heuristics with partial shadow tomography to enable efficient protocols for extracting information from correlated ab initio electronic systems encoded on quantum devices. By proposing the use of a correlation energy functional a...
Classical-quantum gravity as quantum gravity in disguise
Masahiro Hotta, Sebastian Murk, Daniel R. Terno·Jun 18, 2025
Whether gravity must be quantized remains one of the biggest open problems in fundamental physics. Classical-quantum hybrid theories have recently attracted attention as a possible framework in which gravity is treated classically yet interacts consi...
Catalytic $z$-rotations in constant $T$-depth
Isaac H. Kim·Jun 18, 2025
We show that the $T$-depth of any single-qubit $z$-rotation can be reduced to $3$ if a certain catalyst state is available. To achieve an $ε$-approximation, it suffices to have a catalyst state of size polynomial in $\log(1/ε)$. This implies that $\m...
