Prolegomena to a non-equilibrium quantum statistical mechanics

, 1999
We suggest that the framework of quantum information theory, which has been developing rapidly in recent years due to intense activity in quantum computation and quantum communication, is a reasonable starting point to study non-equilibrium quantum ...

Noise-agnostic quantum error mitigation with data augmented neural models

npj Quantum Information
Quantum error mitigation, a data processing technique for recovering the statistics of target processes from their noisy version, is a crucial task for near-term quantum technologies.

Electromagnetically induced transparency and four-wave mixing in a cold atomic ensemble with large optical depth

New Journal of Physics, 2014
We report on the delay of optical pulses using electromagnetically induced transparency (EIT) in an ensemble of cold atoms with an optical depth exceeding 500.

Quantum Chaos & Quantum Computers

, 2000
The standard generic quantum computer model is studied analytically and numerically and the border for emergence of quantum chaos, induced by imperfections and residual inter-qubit couplings, is determined. This phenomenon appears in an isolated quantum computer without any external decoherence.

Single-Ion Implantation for the Development of Si-Based MOSFET Devices with Quantum Functionalities

Advances in Materials Science and Engineering, 2012
Interest in single-ion implantation is driven in part by research into development of solid-state devices that exhibit quantum behaviour in their electronic or optical characteristics. Here, we provide an overview of international research work on single

Highly efficient storage of cavity SPDC single photons in room temperature gradient echo memory

APL Quantum
Efficient quantum memories will be an essential building block of large-scale networked quantum systems and provide a link between flying photonic qubits and atomic or quasi-atomic local quantum processors.

Quantum simulation of the Hubbard model with dopant atoms in silicon

Nature Communications, 2016
The goal of quantum simulation is to probe many-body phenomena in controlled systems, but Fermi-Hubbard phenomena are typically hard to simulate in cold atomic. Here, the authors simulate them with subsurface dopants in silicon, achieving a low effective
