Low-depth fermion routing without ancillas
Nathan Constantinides, Jeffery Yu, Dhruv Devulapalli +6 more·Oct 6, 2025
Routing is the task of permuting qubits in such a way that quantum operations can be parallelized maximally, given constraints on the hardware geometry. When simulating fermions in the Jordan-Wigner encoding with qubits, a one-dimensional nearest-nei...
QuantumBoost: A lazy, yet fast, quantum algorithm for learning with weak hypotheses
Amira Abbas, Yanlin Chen, Tuyen Nguyen +1 more·Oct 6, 2025
The technique of combining multiple votes to enhance the quality of a decision is the core of boosting algorithms in machine learning. In particular, boosting provably increases decision quality by combining multiple weak learners-hypotheses that are...
Casimir Stabilization of Fluctuating Electronic Nematic Order
Ola Carlsson, Sambuddha Chattopadhyay, Jonathan B. Curtis +4 more·Oct 6, 2025
Vacuum cavity control of quantum materials is the engineering of quantum materials systems through electromagnetic zero-point fluctuations. In this work we articulate a generic mechanism for vacuum optical control of correlated electronic order: Casi...
On the Cryptographic Foundations of Interactive Quantum Advantage
Kabir Tomer, Mark Zhandry·Oct 6, 2025
In this work, we study the hardness required to achieve proofs of quantumness (PoQ), which in turn capture (potentially interactive) quantum advantage. A ``trivial'' PoQ is to simply assume an average-case hard problem for classical computers that is...
Engineering the uncontrollable: Steering noisy spin-correlated radical-pairs with coherent and incoherent control
Farhan T. Chowdhury, Luke D. Smith, Daniel R. Kattnig·Oct 6, 2025
The quantum control of spin-correlated radical pairs (SCRPs) holds promise for the targeted manipulation of magnetic field effects, with potential applications ranging from the design of noise-resilient quantum information processors to genetically e...
The role of entropy production and thermodynamic uncertainty relations in the asymmetric thermalization of open quantum systems
Álvaro Tejero·Oct 6, 2025
The asymmetry between heating and cooling in open quantum systems is a hallmark of nonequilibrium dynamics, yet its thermodynamic origin has remained unclear. Here, we investigate the thermalization of a quantum system weakly coupled to a thermal bat...
On the Cryptographic Futility of Non-Collapsing Measurements
Alper Cakan, Dakshita Khurana, Tomoyuki Morimae +3 more·Oct 6, 2025
We investigate quantum analogues of collision resistance and obtain separations between quantum ``one-way'' and ``collision-resistant'' primitives. 1. Our first result studies one-wayness versus collision-resistance defined over quantum circuits that...
One rig to control them all
Chris Heunen, Robin Kaarsgaard, Louis Lemonnier·Oct 6, 2025
Controlled commands -- computations whose execution depends on a separate input -- play a central role in reversible Boolean circuits and quantum circuits. However, existing formalisms typically treat control only implicitly, entangled with other asp...
On Cryptography and Distribution Verification, with Applications to Quantum Advantage
Bruno Cavalar, Eli Goldin, Matthew Gray +2 more·Oct 6, 2025
One of the most fundamental problems in the field of hypothesis testing is the identity testing problem: whether samples from some unknown distribution $\mathcal{G}$ are actually from some explicit distribution $\mathcal{D}$. It is known that when th...
Optimización de la Transmisión de Estados Cuánticos en Cadenas de Qubits usando Deep Reinforcement Learning y Algoritmos Genéticos
Sofía Perón Santana, Ariel Fiuri, Omar Osenda +1 more·Oct 6, 2025
Quantum state transfer (QST) via homogeneous spin chains plays a crucial role in building scalable quantum hardware. A basic quantum state transmission protocol prepares a state in one qubit and transfers it to another through a channel, seeking to m...
Correcting quantum errors using a classical code and one additional qubit
Tenzan Araki, Joseph F. Goodwin, Zhenyu Cai·Oct 6, 2025
Classical error-correcting codes are powerful but incompatible with quantum noise, which includes both bit-flips and phase-flips. We introduce Hadamard-based Virtual Error Correction (H-VEC), a protocol that empowers any classical bit-flip code to co...
Characterization of permutation gates in the third level of the Clifford hierarchy
Zhiyang He, Luke Robitaille, Xinyu Tan·Oct 6, 2025
The Clifford hierarchy is a fundamental structure in quantum computation whose mathematical properties are not fully understood. In this work, we characterize permutation gates -- unitaries which permute the $2^n$ basis states -- in the third level o...
Less is More: On Copy Complexity in Quantum Cryptography
Prabhanjan Ananth, Eli Goldin·Oct 6, 2025
Quantum cryptographic definitions are often sensitive to the number of copies of the cryptographic states revealed to an adversary. Making definitional changes to the number of copies accessible to an adversary can drastically affect various aspects ...
Quantum walks through generalized graph composition
Arjan Cornelissen·Oct 6, 2025
In this work, we generalize the recently-introduced graph composition framework to the non-boolean setting. A quantum algorithm in this framework is represented by a hypergraph, where each hyperedge is adjacent to multiple vertices. The input and out...
Quantum Filtering at Finite Temperature
John Gough·Oct 6, 2025
We pose and solve the problem of quantum filtering based on continuous-in-time quadrature measurements (homodyning) for the case where the quantum process is in a thermal state. The standard construction of quantum filters involves the determination ...
Rapid Mixing of Quantum Gibbs Samplers for Weakly-Interacting Quantum Systems
Štěpán Šmíd, Richard Meister, Mario Berta +1 more·Oct 6, 2025
Dissipative quantum algorithms for state preparation in many-body systems are increasingly recognised as promising candidates for achieving large quantum advantages in application-relevant tasks. Recent advances in algorithmic, detailed-balance Lindb...
Leveraging Analog Neutral Atom Quantum Computers for Diversified Pricing in Hybrid Column Generation Frameworks
Cédrick Perron, Yves Bérubé-Lauzière, Victor Drouin-Touchette·Oct 6, 2025
In this work, we develop new pulse designs and embedding strategies to improve the analog quantum subroutines of hybrid column generation (CG) algorithms based on neutral-atoms quantum computers (NAQCs). These strategies are designed to improve the q...
The NPA hierarchy does not always attain the commuting operator value
Marco Fanizza, Larissa Kroell, Arthur Mehta +4 more·Oct 6, 2025
We show that it is undecidable to determine whether the commuting operator value of a nonlocal game is strictly greater than 1/2. Specifically, there is a computable mapping from Turing machines to /boolean constraint system (BCS) nonlocal games in w...
Visualising Quantum Entanglement Using Interactive Electronic Quantum Dice
B. Folkers, A. van Rossum, A. Brinkman +1 more·Oct 6, 2025
Quantum entanglement remains a challenging concept to teach and visualise due to its microscopic and non-classical nature. We present innovative educational demonstration material consisting of electronic dice that simulate the properties of quantum ...
Efficient Quantum Hermite Transform
Siddhartha Jain, Vishnu Iyer, Rolando D. Somma +2 more·Oct 6, 2025
We present a new primitive for quantum algorithms that implements a discrete Hermite transform efficiently, in time that depends logarithmically in both the dimension and the inverse of the allowable error. This transform, which maps basis states to ...
