Quantum Simulation of Dynamical Response Functions of Equilibrium States
E. Cruz, Dominik S. Wild, M. Bañuls +1 more·May 8, 2025
The computation of dynamical response functions is central to many problems in condensed matter physics. Owing to the rapid growth of quantum correlations following a quench, classical methods face significant challenges even if an efficient descript...
A short review on qudit quantum machine learning
Tiago de Souza Farias, Lucas Friedrich, Jonas Maziero·May 8, 2025
As quantum devices scale toward practical machine learning applications, the binary qubit paradigm faces expressivity and resource efficiency limitations. Multi-level quantum systems, or qudits, offer a promising alternative by harnessing a larger Hi...
A Solovay-Kitaev theorem for quantum signal processing
Z. M. Rossi·May 8, 2025
Quantum signal processing (QSP) studies quantum circuits interleaving known unitaries (the phases) and unknown unitaries encoding a hidden scalar (the signal). For a wide class of functions one can quickly compute the phases applying a desired functi...
Quantum-enabled optical large-baseline interferometry: applications, protocols and feasibility
Zixin Huang, Oleg Titov, Mikolaj K. Schmidt +4 more·May 7, 2025
Optical Very Long Baseline Interferometry (VLBI) offers the potential for unprecedented angular resolution in both astronomical imaging and precision measurements. Classical approaches, however, face significant limitations due to photon loss, backgr...
Dissipation meets conformal interface in open quantum systems: How the relaxation rate is suppressed
Ruhanshi Barad, Qicheng Tang, Xueda Wen·May 7, 2025
Conformal interfaces play an important role in quantum critical systems. In closed systems, the transmission properties of conformal interfaces are typically characterized by two quantities: One is the effective central charge $c_{\text{eff}}$, which...
Measurement-driven quantum advantages in shallow circuits
Chenfeng Cao, Jens Eisert·May 7, 2025
Quantum advantage schemes probe the boundary between classically simulatable and classically intractable quantum dynamics. We explore the impact of mid-circuit measurements on the computational power of quantum circuits. To this effect, we focus on q...
Adiabatic state preparation and thermalization of simulated phase noise in a Rydberg spin Hamiltonian
Tomas Kozlej, Gerard Pelegri, Jonathan D. Pritchard +1 more·May 7, 2025
Laser phase noise is one of the main sources of decoherence in driven Rydberg systems with neutral atoms in tweezer arrays. While the effect of phase noise in the regimes of isolated qubits and few-qubit gate protocols has been studied extensively, t...
Quantum simulation of many-body dynamics with noise-robust Trotter decomposition based on symmetric structures
Bo Yang, Naoki Negishi·May 7, 2025
The Suzuki-Trotter decomposition, which digitalizes quantum time evolution, provides a promising framework for simulating quantum dynamics on quantum hardware and exploring quantum advantage over classical computation. However, conventional Trotter c...
Correlating noise floor with magic and entanglement in Pauli product states
Erika Lloyd, Alexandre Fleury, Marc P. Coons +2 more·May 7, 2025
The dependence of quantum algorithms on state fidelity is difficult to characterize analytically and is best explored experimentally as hardware scales and noisy simulations become intractable. While low fidelity states are often disregarded, they ma...
