Nonadiabatic Self-Healing of Trotter Errors in Digitized Counterdiabatic Dynamics

Mara Vizzuso, Gianluca Passarelli, Giovanni Cantele +3

Trotter errors in digitized quantum dynamics arise from approximating time-ordered evolution under noncommuting Hamiltonian terms with a product formula. In the adiabatic regime, s…

Synchronized Aharonov-Bohm Motifs via Engineered Dissipation

Christopher W. Wächtler, Gloria Platero

The interplay between external gauge fields and lattice geometry can induce extreme localization dynamics through complete destructive interference. We show that combining this flu…

Quantum Error Correction Assisted Axion Search in CMOS Spin Qubit Arrays

Xiangjun Tan, Zhanning Wang

Searches for axion and axionlike dark matter based on solid-state spin qubits are fundamentally limited by strong longitudinal dephasing, which rapidly suppresses the sensitivity g…

Hidden time-nonlocal Floquet symmetries

Sigmund Kohler, Jesús Casado-Pascual

We investigate the Floquet spectrum of a detuned, driven two-level system and show that it exhibits exact quasienergy crossings when the detuning is an integer multiple of the ener…

Classical counterparts of shortcuts to adiabaticity in nonlinear dissipative Lagrangian systems

Jincheng Shi, Yicheng Pan, Yue Ban +1

Shortcuts to adiabaticity (STA) were first developed in quantum dynamics to realize rapid transformations with suppressed residual excitations. Here we show how the same idea can b…

Fast quantum transfer mediated by topological domain walls

Juan Zurita, Charles E. Creffield, Gloria Platero

The duration of bidirectional transfer protocols in 1D topological models usually scales exponentially with distance. In this work, we propose transfer protocols in multidomain SSH…
