Disorder-Assisted Adiabaticity in Correlated Many-Particle Systems
Shang-Jie Liou, Herbert F. Fotso·Mar 10, 2026
We investigate how disorder affects adiabaticity in an interacting quantum system by assessing its effect on the state of the system after an interaction modulation, or interaction ``pulse" ,whereby the interaction is changed from zero to a maximum v...
Operational bounds and diagnostics for coherence in energy transfer
Julia Liebert, Gregory D. Scholes·Mar 10, 2026
Excitation energy transfer in light-harvesting aggregates is highly efficient, yet whether quantum coherence plays an operational role in transport remains debated. A central challenge is that coherence is usually inferred from spectroscopic signatur...

We investigate the influence of phonon degrees of freedom on the qubit dynamics in Jaynes-Cummings (JC) model. A strong qubit-phonon coupling is considered giving rise to Jaynes-Cummings-Holstein (JCH) model. Under anti-adiabatic conditions, we perfo...

We explore optical quantum engineering of phase-parameterized continuous-variable (CV) probe states to exploit nonclassical light to solve the problem of precise phase estimation. The optical interferometer consists of a single beam splitter (BS) wit...
Fermi-pressure-assisted cavity superradiance in a mesoscopic Fermi gas
Francesca Orsi, Ekaterina Fedotova, Rohit Prasad Bhatt +3 more·Mar 9, 2026
We study the superradiant phase transition of a mesoscopic Fermi gas comprising between a few tens and a few thousand $^6$Li atoms in a high-finesse cavity across a wide range of densities. We observe a non-monotonic variation of the superradiant thr...
Parity-dependent Casimir forces and Hall currents for a confined Dirac field
Aitor Fernández, César D. Fosco·Mar 9, 2026
We study a massless Dirac field subjected to two alternative boundary conditions on two parallel thin walls, in d + 1 dimensions. The two configurations correspond to the system being even or odd under reflection about the midplane between the two wa...
Microwave response of electrically driven spins in a three-qubit quantum processor
Tanner M. Janda, Heun Mo Yoo, Connor Nasseraddin +3 more·Mar 9, 2026
In electric dipole spin resonance (EDSR), a single spin is electrically driven in the field gradient produced by a micromagnet. While EDSR has enabled high fidelity gate operations in many devices, there are reports of unexpected non-linearities in t...
Long-time storage of entangled logical states in decoherence-free subspaces
L. Zhang, Y. -L. Xu, Y. -K. Wu +11 more·Mar 7, 2026
The maintenance of quantum entanglement lays the elementary building block of quantum information processing, requiring an integration of long coherence time, sufficient storage capacity, and high-fidelity entangling gates. Here we encode two-qubit e...
Exotic Cooperative Quantum Optics of Moire Exciton Superlattices
Haowei Xu, Wang Yao, Ju Li·Mar 7, 2026
The unique properties of two-dimensional moire systems have been widely studied from many perspectives. However, relatively little work has explored how the real space structure of the moire systems can directly engender novel properties and function...
Qubit Noise Sensing via Induced Photon Loss in a Superconducting Cavity
Nitzan Kahn, Dror Garti, Uri Goldblatt +3 more·Mar 6, 2026
Characterizing noise in superconducting qubits is essential for improving coherence and gate performance. Conventional noise-sensing methods typically use the qubit itself as the sensor, which limits both accessible bandwidth and applicability during...
Operational impact of quantum resources in chemical dynamics
Julia Liebert, Gregory D. Scholes·Mar 6, 2026
Quantum coherence and other non-classical features are widely discussed in chemical dynamics, yet it remains difficult to quantify when such resources are operationally relevant for a given process and observable. While quantum resource theories prov...
Stationary Particle Creation and Entanglement in the Rotating Teo Wormhole: A Quantum Mode-Mixing Approach
Ramesh Radhakrishnan, Gerald Cleaver, William Julius·Mar 6, 2026
Rotating traversable wormholes allow the effects of frame dragging and rotation to be studied in the absence of event horizons. We develop a quantum field theoretic treatment of massless scalar perturbations in the rotating Teo spacetime. This spacet...

Ekaterina Vlasiuk, Manfred Salmhofer, Eugene Demler +1 more·Mar 6, 2026
We investigate how the strong coupling of a superconductor to thermal bosons can enhance its superconducting critical temperature. To tackle this problem, we use a renormalization group approach that allows us to describe the competition between dens...

Surface ion traps confining and manipulating tens of ion qubits have become the leading platform for quantum processors with high quantum volume. These devices employ the Quantum Charge-Coupled Device (QCCD) architecture, wherein multiple trapping zo...
Significant modifications of Lamb shift at small centripetal accelerations
Yan Peng, Jiawei Hu, Hongwei Yu·Mar 6, 2026
We investigate the Lamb shift of centripetally accelerated atoms coupled to electromagnetic vacuum fluctuations. Focusing on a very small orbital radius (so that the tangential speed remains nonrelativistic and the proper centripetal acceleration can...
