    • Charge Noise Spectroscopy Using Coherent Exchange Oscillations in a Singlet-Triplet Qubit 

      Dial, O; Shulman, Michael Dean; Harvey, Shannon Pasca; Bluhm, H.; Umansky, V.; Yacoby, Amir (American Physical Society (APS), 2013)
      Two level systems that can be reliably controlled and measured hold promise as qubits both for metrology and for quantum information science. Since a fluctuating environment limits the performance of qubits in both capacities, ...
    • Demonstration of Entanglement of Electrostatically Coupled Singlet-Triplet Qubits 

      Shulman, Michael Dean; Dial, O; Harvey, Shannon Pasca; Bluhm, H.; Umansky, V.; Yacoby, Amir (American Association for the Advancement of Science (AAAS), 2012)
      Quantum computers have the potential to solve certain problems faster than classical computers. To exploit their power, it is necessary to perform interqubit operations and generate entangled states. Spin qubits are a ...
    • Electron Spin-Flip Correlations Due to Nuclear Dynamics in Driven GaAs Double Dots 

      Pal, Arijeet; Nichols, John; Shulman, Michael; Harvey, Shannon; Umansky, Vladimir; Rashba, Emmanuel; Yacoby, Amir; Halperin, Bertrand (American Physical Society (APS), 2017-01-18)
      We present experimental data and associated theory for correlations in a series of experiments involving repeated Landau-Zener sweeps through the crossing point of a singlet state and a spin-aligned triplet state in a GaAs ...
    • Quenching of dynamic nuclear polarization by spin–orbit coupling in GaAs quantum dots 

      Nichol, John M.; Harvey, Shannon P.; Shulman, Michael D.; Pal, Arijeet; Umansky, Vladimir; Rashba, Emmanuel I.; Halperin, Bertrand I.; Yacoby, Amir (Nature Pub. Group, 2015)
      The central-spin problem is a widely studied model of quantum decoherence. Dynamic nuclear polarization occurs in central-spin systems when electronic angular momentum is transferred to nuclear spins and is exploited in ...
