Thermodynamic uncertainty relations express a trade-off between precision, defined as the noise-to-signal ratio of generic current, and amount associated entropy production. These results have deep consequences for autonomous heat engines operating at steady state, imposing an upper bound their efficiency in terms power yield its fluctuations. In present Letter we analyze different class engines, namely, those which are periodic slow-driving regime. We show that alternative TUR is satisfied,...
This work investigates the consequences of assuming that quantum measurement process -- i.e., physical realization a through an interaction between system to be measured with measuring device is thermodynamically closable, and thus amenable thermodynamic analysis. Our results show this assumption leads fundamental tension following three statements: (i), consistent second third laws thermodynamics; (ii), decomposed into two independent sub-processes: bistochastic device, followed by readout...
We investigate electron paramagnetic resonance spectra of bismuth-doped silicon, at intermediate magnetic fields B≃0.1-0.6 T, theoretically and experimentally (with 9.7 GHz X-band spectra). identify a previously unexplored regime "cancellation resonances," where component the hyperfine coupling is resonant with external field. show that this has accessible consequences for quantum information applications, such as reduction decoherence, fast manipulation coupled electron-nuclear qubits,...
Abstract In classical thermodynamic processes the unavoidable presence of irreversibility, quantified by entropy production, carries two energetic footprints: reduction extractable work from optimal, reversible case, and generation a surplus heat that is irreversibly dissipated to environment. Recently it has been shown in quantum regime an additional irreversibility occurs linked decoherence into energy basis. Here we employ trajectories construct distributions for exchanges, show footprint...
In the quantum regime, third law of thermodynamics implies unattainability pure states. As shown recently, such that a unitary interaction between measured system and measuring apparatus can never implement an ideal projective measurement. this paper, we introduce operational formulation for most general class physical transformations, violation which is both necessary sufficient preparation Subsequently, investigate how constrains measurements observables, or positive operator valued...
There is growing interest in bismuth-doped silicon (Si:Bi) as an alternative to the well-studied proposals for based quantum information processing (QIP) using phosphorus-doped (Si:P). We focus here on implications of its anomalously strong hyperfine coupling. In particular, we analyse detail regime where recent pulsed magnetic resonance experiments have demonstrated potential orders magnitude speedup gates by exploiting transitions that are electron paramagnetic (EPR) forbidden at high...
In thermodynamics, entropy production and work quantify irreversibility the consumption of useful energy, respectively, when a system is driven out equilibrium. For quantum systems, these quantities can be identified at stochastic level by unravelling system's evolution in terms jump trajectories. We here derive general formula for computing joint statistics Markovian whose instantaneous steady states are Gibbs form. If remains close to state all times, then we show that corresponding...
In this paper we investigate the relationship between efficiency of a cyclic quantum heat engine with Hilbert space dimension thermal baths. By means general inequality, show that Carnot can be obtained only when both hot and cold baths are infinitely large. further introducing specific model where constituted ensembles finite-dimensional particles, demonstrate engine's power efficiency, working substance bath particles.
In this paper we introduce a definition for conditional energy changes due to general quantum measurements, as the change in evaluated before, and after, measurement process. By imposing minimal physical requirements on these energies, show that most expression after is simply expected value of Hamiltonian given post-measurement state. Conversely, before process shown be by real component weak Hamiltonian. Our generalises well-known notions distributions internal change, such stochastic...
We study a quantum Szilard engine that is not powered by heat drawn from thermal reservoir, but rather projective measurements. The constituted of system $\mathcal{S}$, weight $\mathcal{W}$, and Maxwell demon $\mathcal{D}$, extracts work via measurement-assisted feedback control. By imposing natural constraints on the measurement processes, such as energy conservation leaving memory intact, we show while can function without it must give up at least one following features are satisfied...
