Entanglement and Non-Markovianity of Quantum Evolutions
Open accessAbstract
We address the problem of quantifying the non-markovian character of quantum time evolutions of general systems in contact with an environment. We introduce two different measures of non-markovianity that exploit the specific traits of quantum correlations and are suitable for opposite experimental contexts. When complete tomographic knowledge about the evolution is available, our measure provides a necessary and sufficient condition to quantify strictly the non-markovianity. In the opposite case, when no information whatsoever is available, we propose a sufficient condition for non-markovianity. Remarkably, no optimization procedure underlies our derivation, which greatly enhances the practical relevance of the proposed criteria.

TL;DR
The paper introduces two measures of non-Markovianity for quantum evolutions that avoid optimization: an entanglement-based sufficient condition usable when the dynamics is unknown, and a necessary-and-sufficient CP-divisibility measure when the dynamical map can be reconstructed. It illustrates the approach with a damped harmonic oscillator coupled to Ohmic and super-Ohmic baths and with a qubit pure-dephasing model.
Key findings
- A sufficient condition for non-Markovianity is \(I(\mathcal{E})>0\), obtained by preparing a maximally entangled system-ancilla state and checking for non-monotonic decay of entanglement; Markovian evolutions give \(I(\mathcal{E})=0\).
- When the dynamical map is known, non-Markovianity is equivalent to the existence of times \(t,\epsilon\) such that \(\mathcal{E}(t+\epsilon,t)\) is not completely positive; the proposed measure uses \(f_{\mathrm{NCP}}\), \(g(t)\ge 0\), and \(I=\int g(t)\,dt\), with normalized \(D_{\mathrm{NM}}=I/(I+1)\) so that \(D_{\mathrm{NM}}=0\) for Markovian and \(D_{\mathrm{NM}}\to 1\) for \(I\to\infty\).
- For a damped harmonic oscillator with Ohmic bath \(J(\omega)=\alpha\omega e^{-\omega/\omega_c}\), the simulations show that \(\alpha\to 0\) approaches Markovian evolution independently of temperature \(T\), while the onset of non-Markovianity is \(T\)-dependent: the coupling \(\alpha\) at which \(I(\mathcal{E})\) becomes nonzero increases with increasing temperature, as does \(I(\mathcal{E})\) for sufficiently large \(\alpha\).
- A super-Ohmic bath \(J(\omega)=\alpha\omega^3 e^{-\omega/\omega_c}\) shows analogous behavior, but the specific value of \(I(\mathcal{E})\) for given \(T\) and \(\alpha\) depends strongly on the bath spectral function; for qubit pure dephasing \(d\rho/dt=\gamma(t)(\sigma_z\rho\sigma_z-\rho)\), \(I\) is proportional to the area of \(\gamma(t)\) below zero, and if negative \(\gamma(t)\) does not tend to zero fast enough then \(I\to\infty\), as with \(\gamma(t)\sim\tan(t)\).
Methods
- Theoretical proposal with two criteria: an entanglement-based sufficient condition for unknown dynamics, and a necessary-and-sufficient condition based on complete positivity of infinitesimal dynamical maps when the evolution can be exactly reconstructed, e.g. by process tomography or a microscopic model.
- For the unknown-dynamics measure, a maximally entangled state \(|\Phi\rangle=\frac{1}{\sqrt{d}}\sum_{n=0}^{d-1}|n\rangle|n\rangle\) is prepared between the system and an isolated ancilla, and the entanglement is monitored over \([t_0,t_{\max}]\).
- Illustrative simulations use a single damped harmonic oscillator coupled to a bath under the rotating wave approximation, with Ohmic and super-Ohmic spectral densities, several temperatures, and varying coupling strengths; entanglement is quantified by logarithmic negativity for Gaussian states.
Limitations
- The paper states that the entanglement-based criterion is only sufficient: there can be non-Markovian quantum evolutions that remain undetected because \(I(\mathcal{E})>0\) is not necessary.
- The necessary-and-sufficient measure requires exact reconstruction of the dynamical map; if \(\mathcal{E}(t,0)\) is not invertible for larger times, \(\mathcal{E}(t+\epsilon,t)\) cannot be defined unequivocally, and the integral measure is finite only if \(g(t)\) decreases fast enough, which “will not be always the case.”
- The simulations use a discrete and finite number of bath oscillators, which the authors say affects the results; they choose parameters so that \(t_{\max}\) is shorter than the bath recurrence time. Evident from the text: the work is theoretical/simulated and does not report experimental validation.

Self-check
Percentages, sums and reported differences re-computed from the paper’s own numbers.
Each contradiction between two passages listed here was confirmed by an independent check.
Unknown-dynamics criterion is called both necessary and sufficient
MinorThe paper says this criterion can miss some non-Markovian evolutions, and later explicitly calls a positive result sufficient for non-Markovianity. Calling it a necessary condition for detecting deviations contradicts those statements.
“This will allow us to give a necessary condition to measure deviations from Markovianity even when the actual form of the dynamics is completely unknown, although some non-Markovian evolutions may be undetected.”
“There can be however non-Markovian quantum evolutions that remain undetected by the proposed measure, given that the requirement I ( E ) > 0 is a sufficient condition for deviation from Markovianity.”
Entanglement derivative need not be strictly negative for Markovian evolution
MinorThe identity evolution is Markovian but leaves entanglement constant, giving a zero derivative rather than an always-negative one.
“if the evolution of the system is Markovian the derivative of E [ ρ SA ( t )] is always negative and I ( E ) = 0.”
“1 is trivially Markovian”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-06, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-06 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
