Quantum Analog-to-Digital Converter for Phase Estimation
E. Caruccio, Simone Roncallo, V. Cimini +9 more·Feb 11, 2025
Traditional quantum metrology assesses precision using the figures of merit of continuous-valued parameter estimation. Recently, quantum digital estimation was introduced: it evaluates the performance information-theoretically by quantifying the numb...
Gigahertz-frequency acousto-optic phase modulation of visible light in a CMOS-fabricated photonic circuit
Jacob Freedman, M. Storey, D. Dominguez +4 more·Feb 11, 2025
Optical phase modulators operating at visible wavelengths are essential components for photonic technologies such as those for quantum control, communications, and laser ranging. However, they remain challenging to implement in scalable, integrated p...
On the Reliability of Information Retrieval From MDS Coded Data in DNA Storage
Serge Kas Hanna·Feb 10, 2025
This work presents a theoretical analysis of the probability of successfully retrieving data encoded with MDS codes (e.g., Reed-Solomon codes) in DNA storage systems. We study this probability under independent and identically distributed (i.i.d.) su...
Practical limitations of the switching theorem for adiabatic state preparation
Thomas D. Cohen, Andrew Li, Hyunwoo Oh +1 more·Feb 10, 2025
The viability of adiabatic quantum computation depends on the slow evolution of the Hamiltonian. The adiabatic switching theorem provides an asymptotic series for error estimates in $1/T$, based on the lowest non-zero derivative of the Hamiltonian an...
Qudit encoding in Rydberg blockaded arrays of atoms
Achille Robert, Tom Bienaimé·Feb 10, 2025
We propose a protocol to realize arbitrary state synthesis and unitary operations on a qudit encoded in the collective dressed states of a Rydberg blockaded array of three-level atoms. This system is isomorphic to the Jaynes-Cummings model and acts a...
Fully optimised variational simulation of a dynamical quantum phase transition on a trapped-ion quantum computer
Lesley Gover, Vinul Wimalaweera, Fariha Azad +3 more·Feb 10, 2025
We time-evolve a translationally invariant quantum state on the Quantinuum H1-1 trapped-ion quantum processor, studying the dynamical quantum phase transition of the transverse field Ising model. This physics requires a delicate cancellation of phase...
Quantum Computing Based Design of Multivariate Porous Materials
Shinyoung Kang, Younghun Kim, Jihan Kim·Feb 10, 2025
Multivariate (MTV) porous materials exhibit unique structural complexities based on their diverse spatial arrangements of multiple building block combinations. These materials possess potential synergistic functionalities that exceed the sum of their...
Quantum nonlocal nonstabilizerness
Dongheng Qian, Jing Wang·Feb 10, 2025
Quantum entanglement and quantum nonstabilizerness are fundamental resources that characterize distinct aspects of a quantum state: entanglement reflects non-local correlations, while nonstabilizerness quantifies the deviation from stabilizer states....
Evaluating the performance of quantum processing units at large width and depth
J. A. Montañez-Barrera, K. Michielsen, David E. Bernal Neira·Feb 10, 2025
Quantum computers have now surpassed classical simulation limits, yet noise continues to limit their practical utility. As the field shifts from proof-of-principle demonstrations to early deployments, there is no standard method for meaningfully and ...

In this work, we explore and propose several quantum circuit mapping strategies to optimize qubit shuttling in scalable quantum computing architectures based on silicon spin qubits. Our goal is to minimize phase errors introduced during shuttling ope...
Fat-Tree QRAM: A High-Bandwidth Shared Quantum Random Access Memory for Parallel Queries
Shifan Xu, A. Lu, Yongshan Ding·Feb 10, 2025
Quantum Random Access Memory (QRAM) is a crucial architectural component for querying classical or quantum data in superposition, enabling algorithms with wide-ranging applications in quantum arithmetic, quantum chemistry, machine learning, and quant...

Laura S. Herzog, Lukas Burgholzer, Christian Ufrecht +2 more·Feb 10, 2025
Despite the continuous advancements in size and robustness of real quantum devices, reliable large-scale quantum computers are not yet available. Hence, classical simulation of quantum algorithms remains crucial for testing new methods and estimating...
Heisenberg-limited calibration of entangling gates with robust phase estimation
K. Rudinger, J. P. Marceaux, A. Hashim +3 more·Feb 10, 2025
The calibration of high-quality two-qubit entangling gates is an essential component in engineering large-scale, fault-tolerant quantum computers. However, many standard calibration techniques are based on randomized circuits that are only quadratica...

L. Peri, A. Gomez-Saiz, Christopher J B Ford +1 more·Feb 10, 2025
Scalable solid-state quantum computers will require integration with analog and digital electronics. Efficiently simulating the quantum-classical electronic interface is hence of paramount importance. Here, we present Verilog-A compact models with a ...
Hamiltonian formulations of centroid-based clustering
Myeonghwan Seong, D. Park·Feb 10, 2025
Clustering is a fundamental task in data science that aims to group data based on their similarities. However, defining similarity is often ambiguous, making it challenging to determine the most appropriate objective function for a given dataset. Tra...
