Abstract

Quantum coherence conservation is shown to be achieved by a very high rate of dissipation of an environmental system coupled with a principal system. This effect is not in the list of previously-known strategies of noise suppression, such as Zeno effect, dynamical decoupling, quantum error correction code, and decoherence free subspace. An analytical solution is found for a simplified model of a single qubit coupled with an environmental single qubit dissipating rapidly. We also show examples of coherence conservation in a spin-boson linear coupling model with a numerical evaluation.

COHERENCE CONSERVATION OF A QUBIT COUPLED TO A DISSIPATING THERMAL ENVIRONMENT

ROBABEH RAHIMI, AKIRA SAITOH, MIKIO NAKAHARA

It is shown that quantum coherence is conserved in a principal system in the case that the system is coupled to a fast dissipating environment [arXiv:0709.0562]. The phenomenon is called the quantum wipe effect. Here, this effect is reviewed and the analytical proof for a model system consisting of a one-qubit system coupled to a fast dissipating environment is extended to an environment at a thermal equilibrium.

Coherence conservation via global coupling: Toward decoherence-free scalable quantum computation

Zhen Su

Decoherence stands as the fundamental bottleneck limiting the physical realization of large-scale fault-tolerant quantum computation. Conventional paradigms rely on passive strategies of environmental isolation and post-hoc quantum error correction, inherently bounded by Markovian approximation, weak-coupling assumptions and prohibitive physical qubit overhead. Breaking away from the dissipative preset of traditional open quantum systems, this work establishes a global system-environment closed dynamical framework with rigorous coherence conservation. Without Markovian coarse-graining or thermal bath approximation \cite{1,5}, we derive the exact non-Markovian reduced dynamic equation and present the necessary and sufficient coupling conditions for strictly conserved quantum coherence. We rigorously prove that decoherence is not an intrinsic fundamental law of quantum mechanics, but an emergent consequence of specific interaction structures and artificial approximation constraints. By constructing structured system-environment coupling Hamiltonians, coherent decay can be frozen at the dynamical root, achieving intrinsic decoherence suppression without error correction, topological quasiparticles or magic state distillation. Numerical simulations verify that coherence remains strictly constant under strong environmental coupling for the proposed coupling scheme, in sharp contrast to conventional decaying dynamics. This work reconstructs the underlying paradigm of open quantum systems, eliminates the decoherence bottleneck at the fundamental level, and provides a novel theoretical route toward large-scale, low-overhead, universal fault-tolerant quantum computation.

Protecting coherence by environmental decoherence: a solvable paradigmatic model

Juan Mauricio Torres, T. H. Seligman

We consider a particularly simple exactly solvable model for a qubit coupled to sequentially nested environments. The purpose is to exemplify the coherence conserving effect of a central system, that has been reported as a result of increasing the coupling between near and far environment. The paradigmatic example is the Jaynes–Cummings Hamiltonian, which we introduce into a Kossakowski–Lindblad master equation using alternatively the lowering operator of the oscillator or its number operator as Lindblad operators. The harmonic oscillator is regarded as the near environment of the qubit, while effects of a far environment are accounted for by the two options for the dissipative part of the master equation. The exact solution allows us to cover the entire range of coupling strength from the perturbative regime to strong coupling analytically. The coherence conserving effect of the coupling to the far environment is confirmed throughout.

Suppression of decoherence dynamics by a dissipative bath at strong coupling

Jitian Chen, Jakub Garwoła, Dvira Segal

Control of decoherence in open quantum systems has become a topic of great interest due to the emergence of quantum technologies that depend on quantum coherent effects. In this work, we investigate the decoherence dynamics of systems coupled to multiple baths through noncommuting systems' operators, and beyond the weak system-bath coupling limit. By building on cooperative effects between baths, we propose a novel strategy to mitigate rapid decoherence. Concretely, we study the dynamics of a qubit coupled to multiple environments with arbitrary interaction strengths, and along different coordinates. Based on insights gained on the decoherence dynamics from the analytical Effective Hamiltonian method, we carry out numerical simulations using the Reaction Coordinate quantum master equation method. In contrast to standard expectations, we show that when the system strongly interacts with a decohering bath, increasing its coupling to a second, dissipative bath slows down the decoherence dynamics. Our work offers insights into the preservation of quantum coherences in open quantum systems based on frustration effects, by utilizing cooperative effects between different heat baths.

A Unified Error Correction Code for Universal Quantum Computing with Identical Particles

S. L. Wu, Lian-Ao Wu

We present a universal fault-tolerant quantum computing architecture based on identical particle qubits (IPQs), where we find that the first-order IPQ - bath interaction fundamentally differs from the conventional first-order qubit-bath interaction. This key distinction necessitates a redesign of existing strategies to fight decoherence. We propose that the simplest quantum error correction code can be realized directly within the physical qubit, provided that conventional correction and restoration are generalized beyond unitary operations to employ physically implementable reversal operations -- naturally placing logical and physical qubits on equal footing. We further demonstrate that dynamical decoupling (DD) remains effective within this unified framework, and that a decoherence-free subspace (DFS) -- like structure emerges. Unlike previous approximate treatments, our analytically solvable IPQ-Bath model enables rigorous testing of these strategies, with numerical simulations validating their effectiveness.

Effects of noise correlations on the performance of quantum error-correcting and -avoiding methods

Stefan Borghoff

In the scope of this work the coherence of quantum information, which is encoded into a qubit register, is analysed. The qubit register is modelled by a spin chain with finite inter-spin distance. In most physically relevant realisations this spin chain irreversibly interacts with a surrounding environment, such that a spin-boson model is used to describe the setting. Due to the interaction decoherence occurs among the qubits register and quantum information gets lost. Mechanisms to slow down this decoherence process are investigated. For that purpose, the techniques of encoding qubits into decoherence-reduced subspaces and quantum error correction are used. In both cases only a linear subspace of the complete available Hilbert space of the spin chain is used as quantum code. The stability of such a code against decoherence has to be evaluated. This evaluation is performed on average over all states within the code by a code fidelity.
