Optical measurement and modeling of interactions between two hole or two electron spins in coupled InAs quantum dots
Alex Greilich, Åtefan C. BÄdescu, Danny Kim +2
Two electron spins in quantum dots coupled through coherent tunneling are generally acknowledged to approximately obey Heisenberg isotropic exchange. This has not been established…
Scalable qubit architecture based on holes in quantum dot molecules
Sophia E. Economou, Juan I. Climente, Antonio Badolato +3
Spins confined in quantum dots are a leading candidate for solid-state quantum bits that can be coherently controlled by optical pulses. There are, however, many challenges to deve…
A spin-photon interface using charge-tunable quantum dots strongly coupled to a cavity
Zhouchen Luo, Shuo Sun, Aziz Karasahin +5
Charged quantum dots containing an electron or hole spin are bright solid-state qubits suitable for quantum networks and distributed quantum computing. Incorporating such quantum d…
Persistent narrowing of nuclear-spin fluctuations in InAs quantum dots using laser excitation
Bo Sun, Colin Ming Earn Chow, Duncan G. Steel +3
We demonstrate the suppression of nuclear spin fluctuations in an InAs quantum dot and measure the timescales of the spin narrowing effect. By initializing for tens of milliseconds…
Quantum control of a spin qubit coupled to a photonic crystal cavity
Samuel G. Carter, Timothy M. Sweeney, Mijin Kim +7
A key ingredient for a quantum network is an interface between stationary quantum bits and photons, which act as flying qubits for interactions and communication. Photonic crystal…
Generation of frequency sidebands on single photons with indistinguishability from quantum dots
Uttam Paudel, Alexander P. Burgers, Michael K. Yakes +3
Generation and manipulation of the quantum state of a single photon is at the heart of many quantum information protocols. There has been growing interest in using phase modulators…
