Weak Gaussian noise in control fields makes dissipation grow linearly with steps in quantum equilibration, yielding a finite optimal step count and minimal dissipated work derived from quantum thermodynamic length.
Thermodynamic recycling of algorithmic failure branches enables information erasure with heat dissipation below the Landauer limit on a quantum processor.
Non-Markovian quantum Langevin analysis of simple LC and bandpass filter couplings to Josephson parametric devices yields modified gain profiles with bandwidth broadening beyond standard Markovian predictions.
Direct use of mechanical qubits from levitated particles for gravimetry achieves m^{-1/2} sensitivity scaling and 0.1 μGal/√Hz performance, outperforming traditional schemes by two orders of magnitude while reaching double standard quantum limits.
A system-level design methodology for scalable fluxonium processors with double-transmon couplers that supports high-fidelity gates, fast reset, and dispersive readout through frequency partitioning under realistic constraints.
Optimal single-site operators for multipartite nonlocality in 1D spin chains exhibit mirror symmetry and remain robust across phases in Ising-type models.
