Entropy Exchange and Thermodynamic Properties of the Single Ion Cooling Process

Entropy, 2019
A complete quantum cooling cycle may be a useful platform for studying quantum thermodynamics just as the quantum heat engine does. Entropy change is an important feature which can help us to investigate the thermodynamic properties of the single ion ...

Quantum Exclusion Process driven by Brownian Motions in terms of quantum Bernoulli noises

Scientific Reports
Quantum Bernoulli noises are the family of annihilation and creation operators on Bernoulli functionals, which satisfy a canonical anti-commutation relation in equal time.

Auger Recombination in Quantum Well Laser with Participation of Electrons in Waveguide Region

Reviews on Advanced Materials Science, 2018
A new mechanism of nonradiative recombination of nonequilibrium carriers in semiconductor quantum wells is suggested and discussed. For a studied Auger recombination process the energy of localized electron-hole pair is transferred to barrier carriers ...

Distinguishing between statistical and systematic errors in quantum process tomography

New Journal of Physics, 2019
It is generally assumed that every process in quantum physics can be described mathematically by a completely positive map. However, experimentally reconstructed processes are not necessarily completely positive due to statistical or systematic errors ...

〈qo|op〉: A quantum object optimizer

SoftwareX
The quantum object optimizer (〈qo|op〉) is a Python library that offers a framework for optimizing quantum circuits to represent quantum objects such as quantum states and Hamiltonians. This optimizer is a quantum compilation process in which an ansatz is

Higher-Order Process Matrix Tomography of a Passively-Stable Quantum Switch

PRX Quantum
The field of indefinite causal order (ICO) has seen a recent surge in interest. Much of this research has focused on the quantum switch, wherein multiple parties act in a superposition of different orders in a manner transcending the quantum circuit ...

Boosting projective methods for quantum process and detector tomography

Physical Review Research
We introduce two methods for quantum process and detector tomography. In the quantum process tomography method, we develop an analytical procedure for projecting the linear inversion estimation of a quantum channel onto the set of completely positive ...
