Non-Markovian evolution: a quantum walk perspective
Pradeep Kumar, Subhashish Banerjee, R. Srikanth +2
Quantum non-Markovianity of a quantum noisy channel manifests typically as information backflow, characterized by the departure of the intermediate map from complete positivity, th…
Probing decoherence in plasmonic waveguides in the quantum regime
S. G. Dlamini, J. T. Francis, X. Zhang +4
We experimentally investigate the decoherence of single surface plasmon polaritons in metal stripe waveguides. In our study we use a Mach-Zehnder configuration previously considere…
Quantum ensembles of quantum classifiers
Maria Schuld, Francesco Petruccione
Quantum machine learning witnesses an increasing amount of quantum algorithms for data-driven decision making, a problem with potential applications ranging from automated image re…
Non-Markovian Dynamics of Discrete-Time Quantum Walks
Subhashish Banerjee, N. Pradeep Kumar, R. Srikanth +2
In the case of the discrete time coined quantum walk the reduced dynamics of the coin shows non-Markovian recurrence features due to information back-flow from the position degree…
Implementing a distance-based classifier with a quantum interference circuit
Maria Schuld, Mark Fingerhuth, Francesco Petruccione
Lately, much attention has been given to quantum algorithms that solve pattern recognition tasks in machine learning. Many of these quantum machine learning algorithms try to imple…
