Maximally entangled and GHz-clocked on-demand photon pair source
Caspar Hopfmann, Weijie Nie, Nand Lal Sharma +3
We present a 1 GHz-clocked, maximally entangled and on-demand photon pair source based on droplet etched GaAs quantum dots using two-photon excitation. By employing these GaP micro…

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…
