Quantum ensembles of quantum classifiers [PDF]
Scientific Reports, 2018 AbstractQuantum machine learning witnesses an increasing amount of quantum algorithms for data-driven decision making, a problem with potential applications ranging from automated image recognition to medical diagnosis. Many of those algorithms are implementations of quantum classifiers, or models for the classification of data inputs with a quantum ...

Quantum circuits for quantum channels [PDF]
Physical Review A, 2017 We study the implementation of quantum channels with quantum computers while minimizing the experimental cost, measured in terms of the number of Controlled-NOT (C-NOT) gates required (single-qubit gates are free). We consider three different models. In the first, the Quantum Circuit Model (QCM), we consider sequences of single-qubit and C-NOT gates ...

What is quantum in quantum randomness? [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018 It is often said that quantum and classical randomness are of different nature, the former being ontological and the latter epistemological. However, so far the question of ‘What is quantum in quantum randomness?’, i.e. what is the impact of quantization and discreteness on the nature of randomness, remains to be answered.

Quantum space and quantum completeness [PDF]
Journal of High Energy Physics, 2018 Abstract Motivated by the question whether quantum gravity can “smear out” the classical singularity we analyze a certain quantum space and its quantum-mechanical completeness. Classical singularity is understood as a geodesic incompleteness, while quantum completeness requires a unique unitary time evolution for test fields ...

Quantumness beyond quantum mechanics [PDF]
Journal of Physics: Conference Series, 2012 Bohmian mechanics allows us to understand quantum systems in the light of other quantum traits than the well-known ones (coherence, diffraction, interference, tunneling, discreteness, entanglement, etc.). Here the discussion focusses precisely on two of these interesting aspects, which arise when quantum mechanics is though within this theoretical ...

Quantum strategies of quantum measurements [PDF]
Physics Letters A, 2001 In classical Monty Hall problem, one player can always win with probability 2/3. We generalize the problem to the quantum domain and show that a fair two-party zero-sum game can be carried out if the other player is permitted to adopt quantum measurement strategy.

QUANTUM ESTIMATION FOR QUANTUM TECHNOLOGY [PDF]
International Journal of Quantum Information, 2009 Several quantities of interest in quantum information, including entanglement and purity, are nonlinear functions of the density matrix and cannot, even in principle, correspond to proper quantum observables. Any method aimed to determine the value of these quantities should resort to indirect measurements and thus corresponds to a parameter ...

A quantum–quantum Metropolis algorithm [PDF]
Proceedings of the National Academy of Sciences, 2012 The classical Metropolis sampling method is a cornerstone of many statistical modeling applications that range from physics, chemistry, and biology to economics. This method is particularly suitable for sampling the thermal distributions of classical systems. The challenge of extending this method to the simulation of arbitrary quantum systems is that,
