Variational Power of Quantum Circuit Tensor Networks

Physical Review X, 2022
We characterize the variational power of quantum circuit tensor networks in the representation of physical many-body ground states. Such tensor networks are formed by replacing the dense block unitaries and isometries in standard tensor networks by local

Measurement-based quantum computing with a spin ensemble coupled to a stripline cavity [PDF]

, 2012
Recently, a new form of quantum memory was proposed. The storage medium is an ensemble of electron spins, coupled to a stripline cavity and an ancillary readout system.

Quantum circuit design search [PDF]

Quantum Machine Intelligence, 2021
This article explores search strategies for the design of parameterized quantum circuits. We propose several optimization approaches including random search plus survival of the fittest, reinforcement learning both with classical and hybrid quantum classical controllers and Bayesian optimization as decision makers to design a quantum circuit in an ...

Analysis of As/GaAs quantum dot solar cells using Suns-Voc measurements [PDF]

, 2014
The performance of InAs/GaAs quantum dot solar cells was investigated up to an optical concentration of 500-suns. A high temperature spacer layer between successive layers of quantum dots was used to reduce the degradation in the open circuit voltage ...
