Combining matrix product states and mean-field theory to capture magnetic order in quasi-1D cuprates
Quentin Staelens, Daan Verraes, Daan Vrancken +3
We study quasi-one-dimensional strongly correlated materials using a multi-step approach based on density functional theory, downfolding techniques, and tensor-network simulations.…
Quantitative Description of Strongly Correlated Materials by Combining Downfolding Techniques and Tensor Networks
Daan Vrancken, Simon Ganne, Daan Verraes +5
We present a high-accuracy procedure for electronic structure calculations of strongly correlated materials. To address limitations in current electronic structure methods, we empl…
High fidelity quantum state tomography of electron-N nuclear hybrid spin register in diamond using Rabi oscillations
Abhishek Shukla, Boo Carmans, Michael Petrov +2
We report on a new quantum state characterisation method, which we call Rabi-based Quantum State Tomography (RQST), that we have validated on single-qubit quantum states, in partic…
High fidelity two-qubit quantum state tomography of Electron-14N hybrid spin register in diamond
Abhishek Shukla, Boo Carmans, Michael Petrov +2
We report here on a major improvement of the control and characterization capabilities of 14N nuclear spin of single NV centers in diamond, as well as on a new method that we have…
