Dual-probe decoherence microscopy: Probing pockets of coherence in a decohering environment [PDF]

, 2012
We study the use of a pair of qubits as a decoherence probe of a non-trivial environment. This dual-probe configuration is modelled by three two-level-systems which are coupled in a chain in which the middle system represents an environmental two-level ...

Quantum information processing using Josephson junctions coupled through cavities [PDF]

, 2003
Josephson junctions have been shown to be a promising solid-state system for implementation of quantum computation. The significant two-qubit gates are generally realized by the capacitive coupling between the nearest neighbour qubits.

Free Electron Qubits

Conference on Lasers and Electro-Optics, 2019
AbstractFree‐electron interactions with laser‐driven nearfields can quantize the electrons’ energy spectrum and provide control over this quantized degree of freedom. The study proposes to use such interactions to promote free electrons as carriers of quantum information and show how to create a qubit on a free electron, which holds promise for ...

Qubits as Parafermions [PDF]

, 2001
Qubits are neither fermions nor bosons. A Fock space description of qubits leads to a mapping from qubits to parafermions: particles with a hybrid boson-fermion quantum statistics.

Pest Localization Using YOLOv5 and Classification Based on Quantum Convolutional Network

Agriculture, 2023
Pests are always the main source of field damage and severe crop output losses in agriculture. Currently, manually classifying and counting pests is time consuming, and enumeration of population accuracy might be affected by a variety of subjective ...

Coupling Superconducting Qubits via a Cavity Bus

, 2007
Superconducting circuits are promising candidates for constructing quantum bits (qubits) in a quantum computer; single-qubit operations are now routine, and several examples of two qubit interactions and gates having been demonstrated.

Entanglement Echoes in Quantum Computation [PDF]

, 2003
We study the stability of entanglement in a quantum computer implementing an efficient quantum algorithm, which simulates a quantum chaotic dynamics. For this purpose, we perform a forward-backward evolution of an initial state in which two qubits are in

Two-dimensional semiconductors pave the way towards dopant-based quantum computing

Beilstein Journal of Nanotechnology, 2018
Since the proposal in 1998 to build a quantum computer using dopants in silicon as qubits, much progress has been made in the nanofabrication of semiconductors and the control of charge and spins in single dopants.

A recursive approach for geometric quantifiers of quantum correlations in multiqubit Schr\"odinger cat states [PDF]

, 2015
A recursive approach to determine the Hilbert-Schmidt measure of pairwise quantum discord in a special class of symmetric states of $k$ qubits is presented. We especially focus on the reduced states of $k$ qubits obtained from a balanced superposition of
