Asymmetric Quantum Shot Noise in Quantum Dots
Hans-Andreas Engel, Daniel Loss
We analyze the frequency-dependent noise of a current through a quantum dot which is coupled to Fermi leads and which is in the Coulomb blockade regime. We show that the asymmetric…
Coulomb scattering in a 2D interacting electron gas and production of EPR pairs
D. S. Saraga, B. L. Altshuler, Daniel Loss +1
We propose a setup to generate non-local spin-EPR pairs via pair collisions in a 2D interacting electron gas, based on constructive two-particle interference in the spin singlet ch…
Dissipation effects in spin-Hall transport of electrons and holes
John Schliemann, Daniel Loss
We investigate the spin-Hall effect of both electrons and holes in semiconductors using the Kubo formula in the correct zero-frequency limit taking into account the finite momentum…
Measurement efficiency and n-shot read out of spin qubits
Hans-Andreas Engel, Vitaly Golovach, Daniel Loss +4
We consider electron spin qubits in quantum dots and define a measurement efficiency e to characterize reliable measurements via n-shot read outs. We propose various implementation…
Optical Detection of Single-Electron Spin Decoherence in a Quantum Dot
Oliver Gywat, Hans-Andreas Engel, Daniel Loss +3
We propose a method based on optically detected magnetic resonance (ODMR) to measure the decoherence time of a single electron spin in a semiconductor quantum dot. The elec…
Exact Born Approximation for the Spin-Boson Model
Daniel Loss, David P. DiVincenzo
Within the lowest-order Born approximation, we present an exact calculation of the time dynamics of the spin-boson model in the Ohmic regime. We observe non-Markovian effects at ze…
