Balancing Cooperativeness and Adaptiveness in the (Noisy) Iterated Prisoner's Dilemma
Adrian Hutter
Ever since Axelrod's seminal work, tournaments served as the main benchmark for evaluating strategies in the Iterated Prisoner's Dilemma (IPD). In this work, we first introduce a s…
Learning in two-player games between transparent opponents
Adrian Hutter
We consider a scenario in which two reinforcement learning agents repeatedly play a matrix game against each other and update their parameters after each round. The agents' decisio…
Quantum Computing with Parafermions
Adrian Hutter, Daniel Loss
Parafermions are exotic non-Abelian quasiparticles generalizing Majorana fermions, which correspond to the case . In contrast to Majorana fermions, braiding of…
Continuous error correction for Ising anyons
Adrian Hutter, James R. Wootton
Quantum gates in topological quantum computation are performed by braiding non-Abelian anyons. These braiding processes can presumably be performed with very low error rates. Howev…
Active error correction for Abelian and non-Abelian anyons
James R. Wootton, Adrian Hutter
We consider a class of decoding algorithms that are applicable to error correction for both Abelian and non-Abelian anyons. This class includes multiple algorithms that have recent…
Parafermions in a Kagome lattice of qubits for topological quantum computation
Adrian Hutter, James R. Wootton, Daniel Loss
Engineering complex non-Abelian anyon models with simple physical systems is crucial for topological quantum computation. Unfortunately, the simplest systems are typically restrict…
Improved HDRG decoders for qudit and non-Abelian quantum error correction
Adrian Hutter, Daniel Loss, James R. Wootton
Hard-decision renormalization group (HDRG) decoders are an important class of decoding algorithms for topological quantum error correction. Due to their versatility, they have been…
Breakdown of Surface Code Error Correction Due to Coupling to a Bosonic Bath
Adrian Hutter, Daniel Loss
We consider a surface code suffering decoherence due to coupling to a bath of bosonic modes at finite temperature and study the time available before the unavoidable breakdown of e…
Relative Thermalization
Lidia del Rio, Adrian Hutter, Renato Renner +1
When studying thermalization of quantum systems, it is typical to ask whether a system interacting with an environment will evolve towards a local thermal state. Here, we show that…
Enhanced thermal stability of the toric code through coupling to a bosonic bath
Fabio L. Pedrocchi, Adrian Hutter, James R. Wootton +1
We propose and study a model of a quantum memory that features self-correcting properties and a lifetime growing arbitrarily with system size at non-zero temperature. This is achie…
Dynamic Generation of Topologically Protected Self-Correcting Quantum Memory
Daniel Becker, Tetsufumi Tanamoto, Adrian Hutter +2
We propose a scheme to dynamically realize a quantum memory based on the toric code. The code is generated from qubit systems with typical two-body interactions (Ising, XY, Heisenb…
An efficient Markov chain Monte Carlo algorithm for the surface code
Adrian Hutter, James R. Wootton, Daniel Loss
Minimum-weight perfect matching (MWPM) has been been the primary classical algorithm for error correction in the surface code, since it is of low runtime complexity and achieves re…
Effective quantum memory Hamiltonian from local two-body interactions
Adrian Hutter, Fabio L. Pedrocchi, James R. Wootton +1
In [Phys. Rev. A 88, 062313 (2013)] we proposed and studied a model for a self-correcting quantum memory in which the energetic cost for introducing a defect in the memory grows wi…
Self-correcting quantum memory with a boundary
Adrian Hutter, James R. Wootton, Beat Röthlisberger +1
We study the two-dimensional toric code Hamiltonian with effective long-range interactions between its anyonic excitations induced by coupling the toric code to external fields. It…
Dependence of a quantum mechanical system on its own initial state and the initial state of the environment it interacts with
Adrian Hutter, Stephanie Wehner
We present a unifying framework to the understanding of when and how quantum mechanical systems become independent of their initial conditions and adapt macroscopic properties (lik…
Almost All Quantum States Have Low Entropy Rates for Any Coupling to the Environment
Adrian Hutter, Stephanie Wehner
The joint state of a system that is in contact with an environment is called lazy, if the entropy rate of the system under any coupling to the environment is zero. Necessary and su…
Quantum entanglement of nanocantilevers
C. Joshi, A. Hutter, F. E. Zimmer +3
We propose a scheme to entangle two mechanical nanocantilevers through indirect interactions mediated by a gas of ultra cold atoms. We envisage a system of nanocantilevers magnetic…
