Simulating the electronic structure of spin defects on quantum computers
Benchen Huang, Marco Govoni, Giulia Galli
We present calculations of the ground and excited state energies of spin defects in solids carried out on a quantum computer, using a hybrid classical/quantum protocol. We focus on…
Five-second coherence of a single spin with single-shot readout in silicon carbide
Christopher P. Anderson, Elena O. Glen, Cyrus Zeledon +11
An outstanding hurdle for defect spin qubits in silicon carbide (SiC) is single-shot readout - a deterministic measurement of the quantum state. Here, we demonstrate single-shot re…
Stability and molecular pathways to the formation of spin defects in silicon carbide
Elizabeth M. Y. Lee, Alvin Yu, Juan J. de Pablo +1
Spin defects in wide-bandgap semiconductors provide a promising platform to create qubits for quantum technologies. Their synthesis, however, presents considerable challenges, and…
First-principles predictions of out-of-plane group IV and V dimers as high-symmetry high-spin defects in hexagonal boron nitride
Jooyong Bhang, He Ma, Donggyu Yim +2
Hexagonal boron nitride (h-BN) has been recently found to host a variety of quantum point defects, which are promising candidates as single-photon sources for solid-state quantum n…
PyCCE: A Python Package for Cluster Correlation Expansion Simulations of Spin Qubit Dynamic
Mykyta Onizhuk, Giulia Galli
We present PyCCE, an open-source Python library to simulate the dynamics of spin qubits in a spin bath, using the cluster-correlation expansion (CCE) method. PyCCE includes modules…
Combined first-principles calculations of electron-electron and electron-phonon self-energies in condensed systems
Han Yang, Marco Govoni, Arpan Kundu +1
We present a method to efficiently combine the computation of electron-electron and electron-phonon self-energies, which enables the evaluation of electron-phonon coupling at the $…
