Trispectrum reconstruction of non-Gaussian noise
Guy Ramon
Using a qubit to probe non-Gaussian noise environments is theoretically studied in the context of classical random telegraph processes. Protocols for control pulses are developed t…
Extended orbital modeling of spin qubits in double quantum dots
Zack White, Guy Ramon
Orbital modeling of two electron spins confined in a double quantum dot is revisited. We develop an extended Hund Mulliken approach that includes excited orbitals, allowing for a t…
Environmental noise spectroscopy with qubits subjected to dynamical decoupling
Piotr Szańkowski, Guy Ramon, Jan Krzywda +2
A qubit subjected to pure dephasing due to classical Gaussian noise can be turned into a spectrometer of this noise by utilizing its readout under properly chosen dynamical decoupl…
Non-Gaussian signatures and collective effects in charge noise affecting a dynamically-decoupled qubit
Guy Ramon
The effects of a collection of classical two-level charge fluctuators on the coherence of a dynamically-decoupled qubit are studied. Distinct dynamics are found at different qubit…
Dynamical decoupling of a singlet-triplet qubit afflicted by a charge fluctuator
Guy Ramon
The efficiency of dynamical decoupling pulse sequences in removing noise due to a charge fluctuator is studied for a singlet-triplet spin qubit. We develop a numerical method to so…
Electrically controlled quantum gates for two-spin qubits in two double quantum dots
Guy Ramon
Exchange-coupled singlet-triplet spin qubits in two gate-defined double quantum dots are considered theoretically. Using charge density operators to describe the double-dot orbital…
