A new version of the Casimir effect where the two plates conduct in specific, different, directions is considered. By direct functional integration the evaluation of the Casimir en…
Quantum tomography of entangled spin-multi-photon states
Dan Cogan, Giora Peniakov, Oded Kenneth +2
We present a novel method for quantum tomography of multi-qubit states. We apply the method to spin-multi-photon states, which we produce by periodic excitation of a semiconductor…
An elementary introduction to the geometry of quantum states with pictures

This is a review of the geometry of quantum states using elementary methods and pictures. Quantum states are represented by a convex body, often in high dimensions. In the case of…
Casimir forces in a T operator approach

We explore the scattering approach to Casimir forces. Our main tool is the description of Casimir energy in terms of transition operators, as presented in Kenneth and Klich, Phys.…
Nano-NMR based flow meter
Daniel Cohen, Ramil Nigmatullin, Oded Kenneth +3
Microfludic channels are now a well established platform for many purposes, including bio-medical research and Lab on a Chip applications. However, the nature of flow within these…

We investigate the self-locomotion of an elongated microswimmer by virtue of the unidirectional tangential surface treadmilling. We show that the propulsion could be almost frictio…

Quantum error mitigation (EM) is a family of hybrid quantum-classical methods for eliminating or reducing the effect of noise and decoherence on quantum algorithms run on quantum h…
Depolarization of Electronic Spin Qubits Confined in Semiconductor Quantum Dots
Dan Cogan, Oded Kenneth, Netanel H. Lindner +6
Quantum dots are arguably the best interface between matter spin qubits and flying photonic qubits. Using quantum dot devices to produce joint spin-photonic states requires the ele…
Deterministic Generation of a Cluster State of Entangled Photons
