Towards Predictive Quantum Algorithmic Performance: Modeling Time-Correlated Noise at Scale
Amit Jamadagni, Gregory Quiroz, Eugene Dumitrescu
Combining tensor network techniques with quantum autoregressive moving average models, we quantify the effects of time-correlated noise on quantum algorithms and predict their perf…
Composite-Dimensional Topological Codes with Boundaries and Defects
Mohamad Mousa, Amit Jamadagni, Eugene Dumitrescu
We introduce new algorithms and provide example constructions of stabilizer models for the gapped boundaries, domain walls, and defects of Abelian composite-dimensional twiste…
Gauge-Fixing Quantum Density Operators At Scale
Amit Jamadagni, Eugene Dumitrescu
We provide theory, algorithms, and simulations of non-equilibrium quantum systems using a one-dimensional (1D) completely-positive (CP), matrix-product (MP) density-operator ()…
Efficient computation of topological order
Louis Fraatz, Amit Jamadagni, Hendrik Weimer
We analyze the computational aspects of detecting topological order in a quantum many-body system. We contrast the widely used topological entanglement entropy with a recently intr…
Kibble-Zurek mechanism and errors of gapped quantum phases
Amit Jamadagni, Javad Kazemi, Arpan Bhattacharyya
Kibble-Zurek mechanism relates the domain of non-equilibrium dynamics with the critical properties at equilibrium. It establishes a power law connection between non-equilibrium def…
Benchmarking Quantum Computer Simulation Software Packages: State Vector Simulators
Amit Jamadagni, Andreas M. Läuchli, Cornelius Hempel
Rapid advances in quantum computing technology lead to an increasing need for software simulators that enable both algorithm design and the validation of results obtained from quan…
Learning of error statistics for the detection of quantum phases
Amit Jamadagni, Javad Kazemi, Hendrik Weimer
We present a binary classifier based on neural networks to detect gapped quantum phases. By considering the errors on top of a suitable reference state describing the gapped phase,…
