Kilometer-Scale Ion-Photon Entanglement with a Metastable $^{88}$Sr$^{+}$ Qubit
Mika A. Zalewski, Denton Wu, Ana Luiza Ferrari +2 more·Jun 12, 2025
We demonstrate entanglement between the polarization of an infrared photon and a metastable $^{88}$Sr$^+$ ion qubit. This entanglement persists after transmitting the photon over a $2.8\:$km long commercial fiber deployed in an urban environment. Tom...
A cavity array microscope for parallel single-atom interfacing
Adam L. Shaw, Anna Soper, Danial Shadmany +8 more·Jun 12, 2025
Neutral atom arrays and optical cavity QED systems have developed in parallel as central pillars of modern experimental quantum science. While each platform has demonstrated exceptional capabilities-such as high-fidelity quantum logic in atom arrays,...
Coupled Lindblad pseudomode theory for simulating open quantum systems
Zhen Huang, Gunhee Park, Garnet Kin-Lic Chan +1 more·Jun 12, 2025
Coupled Lindblad pseudomode theory is a promising approach for simulating non-Markovian quantum dynamics on both classical and quantum platforms, with dynamics that can be realized as a quantum channel. We provide theoretical evidence that the number...
Spacetime quantum mechanics for bosonic and fermionic systems
N. L. Diaz, R. Rossignoli·Jun 12, 2025
We provide a Hilbert space approach to quantum mechanics where space and time are treated on an equal footing. Our approach replaces the standard dependence on an external classical time parameter with a spacetime-symmetric algebraic structure, there...
Synchronization for Fault-Tolerant Quantum Computers
Satvik Maurya, Swamit S. Tannu·Jun 12, 2025
Quantum Error Correction (QEC) codes store information reliably in logical qubits by encoding them in a larger number of less reliable qubits. The surface code, known for its high resilience to physical errors, is a leading candidate for fault-tolera...
Sequential transmission at short times
Archishna Bhattacharyya·Jun 12, 2025
We show that it is possible to transmit and preserve information at short time scales over an n-fold composition of quantum channels $(\Xi^n)_{n \in \mathbb{N}}$ modelled as a discrete quantum Markov semigroup, long enough to generate entanglement at...
Drift-resilient mid-circuit measurement and state preparation error mitigation for dynamic circuits
Jader P. Santos, R. Uzdin·Jun 12, 2025
Quantum error mitigation (QEM) for dynamic circuits, i.e., those incorporating mid-circuit measurements and feedforward, is important for two key reasons. First, quantum error correction (QEC) circuits are instances of dynamic circuits, and therefore...
Ultrahigh threshold nonstabilizer nonlinear quantum error correcting code
M.W. Grafe, Kaixuan Zhou, Zaman Tekin +5 more·Jun 12, 2025
We introduce a novel type of quantum error correcting code, called the spinor code, based on spaces defined by total spin. The code is a nonstabilizer code, and is also a nonlinear quantum error correcting code, meaning that quantum information is en...
A Time-Symmetric Quantum Algorithm for Direct Eigenstate Determination
Shijie Wei, Jingwei Wen, Xiaogang Li +4 more·Jun 12, 2025
Time symmetry in quantum mechanics, where the current quantum state is determined jointly by both the past and the future, offers a more comprehensive description of physical phenomena. This symmetry facilitates both forward and backward time evoluti...
Kibble-Zurek dynamical scaling hypothesis in the Google analog-digital quantum simulator of the XX model
Yintai Zhang, F. A. Bayocboc, Jacek Dziarmaga·Jun 12, 2025
State-of-the-art tensor networks are employed to simulate the Hamiltonian ramp in the analog-digital quantum simulation of the quantum phase transition to the quasi-long-range ordered phase of the two-dimensional square-lattice $XX$ model [T.I. Ander...
Controlling quantum chaos via Parrondo strategies on noisy intermediate-scale quantum hardware.
Aditi Rath, Dinesh Kumar Panda, Colin Benjamin·Jun 12, 2025
Advancements in noisy intermediate-scale quantum (NISQ) computing are steadily pushing these systems toward outperforming classical supercomputers on specific well-defined computational tasks. In this work we explore and control quantum chaos in NISQ...
Automated All-RF Tuning for Spin Qubit Readout and Control
Cornelius Carlsson, J. Saez-Mollejo, F. Fedele +5 more·Jun 12, 2025
Efficient tuning of spin qubits remains a major bottleneck in scaling semiconductor quantum dot-based quantum processors. A key challenge is the rapid identification of gate voltage regimes suitable for qubit initialisation, control, and readout. Her...
Non-Abelian dynamics on a cube: improving quantum compilation through qudit-based simulations
Jacky Jiang, N. Klco, Olivia Di Matteo·Jun 12, 2025
Recent developments in mapping lattice gauge theories relevant to the Standard Model onto digital quantum computers identify scalable paths with well-defined quantum compilation challenges toward the continuum. As an entry point to these challenges, ...
Adaptive Job Scheduling in Quantum Clouds Using Reinforcement Learning
Waylon Luo, Jiapeng Zhao, Tong Zhan +1 more·Jun 12, 2025
Present-day quantum systems face critical bottlenecks, including limited qubit counts, brief coherence intervals, and high susceptibility to errors—all of which obstruct the execution of large and complex circuits. The advancement of quantum algorith...
A purely Quantum Generative Modeling through Unitary Scrambling and Collapse
Yihua Li, Jiayi Chen, Tamanna S. Kumavat +1 more·Jun 12, 2025
Quantum computing offers fundamentally more expressive mechanisms for generative modeling, yet current approaches remain constrained by classical neural components that bottleneck quantum capability and hardware efficiency. We propose the Quantum Scr...
Lieb-Mattis states for robust entangled differential phase sensing
Raphael Kaubruegger, Diego Fallas Padilla, Athreya Shankar +9 more·Jun 11, 2025
We explore a two-node, entanglement-enhanced sensor network for differential phase sensing that exploits decoherence-free subspaces to suppress common-mode noise, a primary limitation of many state-of-the-art quantum sensors. We identify a class of e...
Universality of stochastic control of quantum chaos with measurement and feedback
Andrew A. Allocca, Devesh K. Verma, Sriram Ganeshan +1 more·Jun 11, 2025
We investigate universal features of measurement-and-feedback control of quantum chaotic dynamics by examining the quantum Arnold cat map, a paradigmatic model of quantum chaos. Inspired by probabilistic control of classical chaos, our protocol stoch...
Cooling a Qubit using n Others
Jake Xuereb, Benjamin Stratton, Alberto Rolandi +3 more·Jun 11, 2025
In the task of unitarily cooling a quantum system with access to a larger quantum system, known as the machine or reservoir, how does the structure of the machine impact an agent's ability to cool and the complexity of their cooling protocol? Focusin...
Certifying asymmetry in the configuration of three qubits
Abdelmalek Taoutioui, Gábor Drótos, Tamás Vértesi·Jun 11, 2025
Symmetry restrictions limit the types of tasks that can be achieved with a given set of quantum states. Therefore, any breaking of these symmetries could potentially be exploited as a resource for quantum communication. Here we demonstrate this opera...
Detecting (emergent) continuous symmetry of criticality via subsystem's entanglement spectrum
Bin-Bin Mao, Zhe Wang, Bin-Bin Chen +1 more·Jun 11, 2025
The (emergent) symmetry of a critical point is one of the most important information to identify the universality class and effective field theory, which is fundamental for various critical theories. However, the underlying symmetry so far can only b...
