Realization of Trapped Ion Dynamics in the Strong-Field Regime and Non-Markovianity
Kamran Rehan, Hengchao Tu, Tadeu Tassis +5 more·Oct 23, 2025
Probing quantum dynamics in the strong-field regime is critical for advancing our understanding of controlled quantum systems and developing robust quantum technologies. In this work, we experimentally investigate the dynamics of a trapped ion where ...
Robust GHz-range AC Magnetometry with an ensemble of NV Centers in Diamond using Concatenated Continuous Dynamical Decoupling
Takuya Kitamura, Genko Genov, Alon Salhov +5 more·Oct 23, 2025
Sub-picotesla level magnetometry has been demonstrated using negatively-charged nitrogen-vacancy (NV) centers in diamond by increasing the number of spins simultaneously used for sensing in an NV ensemble. However, such scale-up often introduces spat...
Quantum Coherence as a Thermodynamic Resource Beyond the Classical Uncertainty Bound
Shanhe Su, Cong Fu, Ousi Pan +3 more·Oct 23, 2025
The precision of nonequilibrium thermodynamic systems is fundamentally limited, yet how quantum coherence shapes these limits remains largely unexplored. A general theoretical framework is introduced that explicitly links quantum coherence to thermod...
Multiplexed ion-ion entanglement over $1.2$ kilometer fibers
Z. B. Cui, Z. Q. Wang, P. Y. Liu +14 more·Oct 23, 2025
Quantum networks and quantum repeaters represent the promising avenues for building large-scale quantum information systems, serving as foundational infrastructure for distributed quantum computing, long-distance quantum communication, and networked ...
Restoring Quantum Superiority of Noisy Quantum Illumination
Wei Wu, Jun-Hong An·Oct 23, 2025
Quantum illumination uses quantum entanglement as a resource to enable higher-resolution detection of low-reflectivity targets than is possible with classical techniques. This revolutionary technology could transform modern radar. However, it is wide...
Complete characterisation of state conversions by work extraction
Chung-Yun Hsieh, Manuel Gessner·Oct 23, 2025
We introduce a thermodynamic work extraction task that describes the energy storage enhancement of quantum systems, which is naturally related to quantum battery's charging process. This task induces majorisation-like conditions that provide a necess...
Phase Separation in Kitaev Chain
Kazuhiro Kuboki·Oct 23, 2025
Kitaev chain is a one-dimensional spinless fermion model that has $p$-wave superconducting (SC) states and Majorana zero modes at the edge. Usually this model is analyzed by taking only SC order parameter (OP) into account, but the situation signific...
Factorizability of optimal quantum sequence discrimination under maximum-confidence measurements
Donghoon Ha, Jeong San Kim·Oct 23, 2025
We consider the discrimination of quantum sequences under maximum-confidence measurements and show that the optimal discrimination of a quantum sequence ensemble can always be factorized into that of each individual ensemble. In other words, the opti...
Non-Markovianity in Quantum Information Processing: Interplay with Quantum Error Mitigation
Suguru Endo, Hideaki Hakoshima, Tomohiro Shitara·Oct 23, 2025
Non-Markovian dynamics are typically present in the dynamics of open quantum systems. Despite the rich structure of non-Markovian dynamics, their relevance to quantum information processing (QIP) has been rarely discussed. In this work, we demonstrat...
Emergent time and more from wavefunction collapse in general relativity
Sung-Sik Lee·Oct 23, 2025
In this paper, we further develop a recently proposed theory of time based on wavefunction collapse in general relativity. It is based on the postulations that quantum states, which violate the momentum and Hamiltonian constraints, represent instance...
Parametric phase modulation in superconducting circuits
Zhuang Ma, Xianke Li, Hongyi Shi +4 more·Oct 23, 2025
Parametric modulation, valued for its versatility, is widely employed in superconducting circuits for quantum simulations and high-fidelity two-qubit gates. Conventionally, the qubit coupling strength is determined by the amplitude of the parametric ...
Kondo breakdown induced by the non-Hermitian complex hybridization
Kazuki Yamamoto, Masaya Nakagawa, Norio Kawakami·Oct 23, 2025
Recently, a non-Hermitian Anderson impurity model with one-body loss has been studied in [Phys. Rev. B 111, 125157 (2025)}], and it has been demonstrated that the renormalization effect generated by strong correlations counterintuitively changes the ...
Unveiling non-Hermitian band structures with non-Bloch supercells
Jia-Xin Zhong, Jing Lin, Kai Chen +3 more·Oct 23, 2025
Real-valued band structures are foundational to analyzing periodic systems within the Hermitian description and have been experimentally well-established over recent decades. In contrast, non-Hermitian systems exhibit complex band structures where bo...
Efficient Floating-Point Arithmetic on Fault-Tolerant Quantum Computers
José E. Cruz Serrallés, Oluwadara Ogunkoya, Do{g}a Murat Kürkçüo{g}lu +5 more·Oct 23, 2025
We propose a novel floating-point encoding scheme that builds on prior work involving fixed-point encodings. We encode floating-point numbers using Two's Complement fixed-point mantissas and Two's Complement integral exponents. We used our proposed a...
Quantum mysteries explained in digestible form
Alejandro Hnilo·Oct 23, 2025
Years ago, Itamar Pitowski asked two relevant questions: Why microphysical (quantum) phenomena and classical phenomena differ in the way they do? and, what kind of explanation could qualify as a reasonable one? I argue that both questions can be answ...
A Full Stack Framework for High Performance Quantum-Classical Computing
Xin Zhan, K. Grace Johnson, Aniello Esposito +5 more·Oct 23, 2025
To address the growing needs for scalable High Performance Computing (HPC) and Quantum Computing (QC) integration, we present our HPC-QC full stack framework and its hybrid workload development capability with modular hardware/device-agnostic softwar...
Electronically-controlled one- and two-qubit gates for transmon quasicharge qubits
Nicholas M. Christopher, Deniz E. Stiegemann, Abhijeet Alase +1 more·Oct 23, 2025
Superconducting protected qubits aim to achieve sufficiently low error rates so as to allow realization of error-corrected, utility-scale quantum computers. A recent proposal encodes a protected qubit in the quasicharge degree of freedom of the conve...
Variational quantum simulation of many-body dissipative dynamics on a superconducting quantum processor
Huan-Yu Liu, Tai-Ping Sun, Zhao-Yun Chen +7 more·Oct 23, 2025
Open quantum systems host a wide range of intriguing phenomena, yet their simulation on well-controlled quantum devices is challenging, owing to the exponential growth of the Hilbert space and the inherently non-unitary nature of the dynamics. Here w...
Circuit-based cavity magnonics in the ultrastrong and deep-strong coupling regimes
Takahiro Chiba, Ryunosuke Suzuki, Takashi Otaki +1 more·Oct 23, 2025
We theoretically study nonperturbative strong-coupling phenomena in cavity magnonics systems in which the uniform magnetization dynamics (magnons) in a ferromagnet is coupled to the microwave magnetic field (photons) of a single LC resonator. Startin...
